Instead of using private controller methods, simple_command can be used.

Here is a simple diagram of the process:

Token-based authentication is stateless - it does not store anything on the server but creates a unique encoded token that gets checked every time a request is made.

Token-based authentication (also known as JSON Web Token authentication) is a new way of handling the authentication of users in applications. It is an alternative to session-based authentication.

A "piece of code" is worth a thousand words. All the verbosity in the previous answers didn't light the bulb in my head the way this piece of code did. And now that that verbosity makes absolutely perfect sense :)

The thing most obvious about the type systems of Java, C, C++, Pascal, and many other widely-used “industry” languages is not that they are statically typed, but that they are explicitly typed.In other words, they require lots of type declarations. (In the world of less explicitly typed languages, where these declarations are optional, they are often called “type annotations”.) This has nothing to do with static types. continued

One language that is currently being developed, Rascal, takes a hybrid approach allowing dynamic typing within functions but enforcing static typing for the function signature.

describe AuthenticateUser do subject(:context) { described_class.call(username, password) } describe '.call' do context 'when the context is successful' do let(:username) { 'correct_user' } let(:password) { 'correct_password' } it 'succeeds' do expect(context).to be_success end end context 'when the context is not successful' do let(:username) { 'wrong_user' } let(:password) { 'wrong_password' } it 'fails' do expect(context).to be_failure end end end end

`.call` is a shortcut for `.new(args).call`

This question is not duplicate as you marked it. My situation is different

I was getting an error indicating I was using an invalid access_token. It turns out that I wasn't waiting for getLoginStatus to complete prior to making an API call

I disagree. What is expressed is an attempt to solve X by making something that should maybe be agnostic of time asynchronous. The problem is related to design: time taints code. You have a choice: either you make the surface area of async code grow and grow or you treat it as impure code and you lift pure synchronous logic in an async context. Without more information on the surrounding algorithm, we don't know if the design decision to make SymbolTable async was the best decision and we can't propose an alternative. This question was handled superficially and carelessly by the community.

The problem with this pile of questions is that, instead of helping the OP get out of the X Y problem, people stay focussed on Y, mark the question as a duplicate of Y in a matter of minutes and X is never properly addressed.

because the value isn't there yet. A promise is just a marker that it will be available at some point in the future. You cannot convert asynchronous code to synchronous, though. If you order a pizza, you get a receipt that tells you that you will have a pizza at some point in the future. You cannot treat that receipt as the pizza itself, though. When you get your number called you can "resolve" that receipt to a pizza. But what you're describing is trying to eat the receipt.

Note that because this request uses your app secret, it must never be made in client-side code or in an app binary that could be decompiled. It is important that your app secret is never shared with anyone. Therefore, this API call should only be made using server-side code.

for security, app access token should never be hard-coded into client-side code, doing so would give everyone who loaded your webpage or decompiled your app full access to your app secret, and therefore the ability to modify your app. This implies that most of the time, you will be using app access tokens only in server to server calls.

once you have an access token you can use it to make calls from a mobile client, a web browser, or from your server to Facebook's servers. If a token is obtained on a client, you can ship that token down to your server and use it in server-to-server calls. If a token is obtained via a server call, you can also ship that token up to a client and then make the calls from the client.

Apple does not allow moving tokens to servers.

A User access token is used if your app takes actions in real time, based on input from the user. This kind of access token is needed any time the app calls an API to read, modify or write a specific person's Facebook data on their behalf. A User access tokens is generally obtained via a login dialog and requires a person to permit your app to obtain one.

It's also a good idea to run qualitative usability tests to understand how people are reacting to what they see.

It's incredibly important to test your Facebook Login flow under a variety of conditions, and we've built a robust testing plan for you to follow.

Are you two serious? Instead of advocating to fix this bug you go out of your way to post another bug report to advocate the devs to dig in their heels?!

An expired ID token does not mean the user is signed out.

Something that you're trying to keep the same, in order to achieve goal X (such as a "log lookup time" above).

An invariant is like a rule or an assumption that can be used to dictate the logic of your program.

An invariant (in common sense) means some conditions that must be true at some point in time or even always while your program is executing. e.g. PreConditions and PostConditions can be used to assert some conditions that must be true when a function is called and when it returns. Object invariants can be used to assert that a object must have a valid state throughout the time it exists. This is the design by contract principle.

Modern cars, however, use a single stick that pivots around among the gears. It's designed in such a way that, on a modern stick-shift car, it is not possible to engage two gears at the same time.

In OOP, an invariant is a set of assertions that must always hold true during the life of an object for the program to be valid. It should hold true from the end of the constructor to the start of the destructor whenever the object is not currently executing a method that changes its state.

The age of a parent is greater than the age of their biological children.

an invariant is something like of a fixed relationship between varying entities. For example, your age will always be less than that compared to your biological parents. Both your age, and your parent's age changes in the passage of time, but the relationship that i mentioned above is an invariant.

For instance, a binary search tree might have the invariant that for every node, the key of the node's left child is less than the node's own key. A correctly written insertion function for this tree will maintain that invariant. As you can tell, that's not the sort of thing you can store in a variable: it's more a statement about the program. By figuring out what sort of invariants your program should maintain, then reviewing your code to make sure that it actually maintains those invariants, you can avoid logical errors in your code.

The secure OAuth 2.0 protocol lets you safely link a user's Google Account with their account on your platform, thereby granting Google applications and devices access to your services.

Use cases

This can result in an unwanted increase in fraudulent account creations, or worse; attackers successfully stealing social media account credentials from legitimate users.

The established link grants Google access to the data the user consents to share.

Benefits for developers include:

Benefits for users include:

Users can start and complete the account linking process in your app, an environment they are already familiar with. Users do not require login credentials because they have already been authenticated on the device and in your mobile app.

A traditional account linking flow requires the user to enter their credentials in the browser. The use of App Flip defers user sign-in to your Android app, which allows you to leverage existing authorizations. If the user is signed in to your app, they don't need to re-enter their credentials to link their account.

You can create variations of your email address where all messages arrive in your current inbox. Just add a plus sign (+) and any word before the @ sign in your current address.

To simulate a Google app and trigger the intent which launches your app, download and install the App Flip Test Tool

To implement App Flip, you need to modify the user authorization code in your app to accept a deep link from Google.

To perform account linking with OAuth and Google Sign-In, follow these general steps: First, ask the user to give consent to access their Google profile. Use the information in their profile to check if the user account exists. For existing users, link the accounts. If you can't find a match for the Google user in your authentication system, validate the ID token received from Google. You can then create a user based on the profile information contained in the ID token.

Don't reply or click any links in a spam message Replying to, clicking on links within, or even attempting to unsubscribe from spam emails typically only informs the sender that they have found an active email address to which they'll send more spam emails.

Whether a personalized button or a generic text button displays has no impact on the UX flows after the button is clicked. The account displayed in the personalized button is not automatically selected.

A personalized button gives users a quick indication of the session status, both on Google's side and on your website, before they click the button. This is especially helpful to end users who visit your website only occasionally. They may forget whether an account has been created or not, and in which way. A personalized button reminds them that Sign In With Google has been used before. Thus, it helps to prevent unnecessary duplicate account creation on your website.

The United States was lagging in the adoption of real-time payments (RTP) before the launch of FedNow because the market is structured on choice rather than mandate

Our freedom of choice in a competitive society rests on the fact that, if one person refuses to satisfy our wishes, we can turn to another. But if we face a monopolist we are at his absolute mercy.

One loss due to this change is the ability to represent an invalid UUID (vs a NIL UUID).

Compared with simple clients, modern clients are generally much easier to use and more Ruby-like

Modern clients are produced by a modern code generator, combined with hand-crafted functionality for some services.

Most modern clients connect to high-performance gRPC endpoints, although a few are backed by REST services.

The libraries in this repo are simple REST clients. These clients connect to HTTP/JSON REST endpoints and are automatically generated from service discovery documents. They support most API functionality, but their class interfaces are sometimes awkward.

Web server applications

It is generally a best practice to request scopes incrementally, at the time access is required, rather than up front. For example, an app that wants to support saving an event to a calendar should not request Google Calendar access until the user presses the "Add to Calendar" button; see Incremental authorization.

After logging in, the user is asked whether they are willing to grant one or more permissions that your application is requesting. This process is called user consent.

Given the security implications of getting the implementation correct, we strongly encourage you to use OAuth 2.0 libraries when interacting with Google's OAuth 2.0 endpoints. It is a best practice to use well-debugged code provided by others, and it will help you protect yourself and your users. For more information, see Client libraries.

Cross-Account Protection does not currently send security events for Google Workspace (formerly G Suite) users.

For example, if a user's Google Account were compromised, you could temporarily disable Sign In With Google for that user and prevent account recovery emails from being sent to the user's Gmail address.

After you have verified the token, check if the user is already in your user database. If so, establish an authenticated session for the user. If the user isn't yet in your user database, create a new user record from the information in the ID token payload, and establish a session for the user. You can prompt the user for any additional profile information you require when you detect a newly created user in your app.

If so, establish an authenticated session for the user.

Warning: Do not accept plain user IDs, such as those you can get with the GoogleUser.getId() method, on your backend server. A modified client application can send arbitrary user IDs to your server to impersonate users, so you must instead use verifiable ID tokens to securely get the user IDs of signed-in users on the server side.

If I wanted to integrate this with an existing login system, “signing out” would mean signing out of my own application (and not out of my Google account).

I sign in with my Google account everywhere I can to avoid having yet another password on another random website.

useInterval( () => { if (typeof window !== "undefined" && window.google) { setGoogle(window.google); setGoogleIsLoading(false); } }, googleIsLoading ? 100 : null );

We didn't add this initially because Google is not the only form of authentication we offer and it could get annoying for users that sign up with GitHub or username and password to see the Google popup all the time.

Sign in with Google is based on OAuth 2.0.

At a later time, when accessing data from Google is required, you call the authorization API to ask for the consent and get access tokens for data access. This separation complies with our recommended incremental authorization best practice, in which the permissions are requested in context.

OAuth 2.0 is also the industry-standard protocol for authorization. It provides for a set of endpoints with which relying parties integrate using HTTP.

"Sign up with Google"

To mitigate this latency issue, the buttons are rendered in 2 steps, as follows:

The Sign in with Google button redirect flow always uses the POST method to submit the credential to your web server, whereas OAuth redirect normally uses the GET method.

The OAuth 2.0 specification considers HTTP redirection, but lacks guidance on rendering pop-up dialogs.

The user's Google account sign-in status and your app are independent of each other, except during the sign-in moment itself when you know that the user has successfully authenticated and is signed into their Google account. Users may remain signed in, they may sign out, or switch to a different Google account while maintaining an active, signed-in session on your website.

Automatic Sign-in can only happen with One Tap UX, not with the Sign in with Google button UX.

Due to security reasons, it's not allowed to add new Google sessions in an iframe.

are triggered only when users have signed in to Google before loading your web pages. This step is optional for the Sign in with Google button flow, since users are prompted to sign in to Google when the button is pressed.

In contrast to One Tap, the Sign in with Google button flow must be triggered by a user gesture.

A personalized button reminds end users that they have used Sign in with Google before, and thus helps to prevent unnecessary duplicate account creation on your website. This is especially helpful to end users who visit your website only occasionally. They may forget the login methods they used.

Sign in with Google for Web doesn't support silent sign in, in which case a credential is returned without any UI displayed. End users always see some UI, manual or automatic sign in, when a login credential is returned from Google to the relying party. This improves user privacy and control.

Authentication establishes who someone is, and is commonly referred to as user sign-up or sign-in. Authorization is the process of granting or rejecting access to data or resources.

The signed-in status of a Google Account, and your app's session state and signed-in status are distinct, separate concepts. User sign-in status to their Google Account and your app are independent of each other

To improve user privacy, display moment notifications are intentionally delayed a random amount of time when FedCM is enabled.

If you have any Workspace organization, and the app is only accessible to users within their own org, then we allow non-public domains for projects in "Internal" mode. See this link on how to make the project internal.

In development, I was able to reset the exponential cool down by removing the g_state cookie. One method for this might be to add a development-only "Clear Google One Tap Cookie" link that run an server-side action to remove the g_state cookie and then redirect back to the previous page.

The PSL nor its volunteers prescribe what browsers do with entries or their recognition/handling of entries, default behaviours, or other handling. Browsers do what browsers do, diversely, and the PSL is not the boss of them.

It does provide an answer. The issue is that the Google form validates that the user has input a valid looking URL. So he needs to input an arbitrary, but valid URL, and then add that to /etc/hosts so his browser will resolve it to the address of his devserver. The question and answer are both fine as is and don't require any critique or clarification.

You can set "Authorized redirect URI" to local IP (like http://127.0.0.1/callback), it's working fine for me. What really agonizing is that google don't allow user to config an external IP (let's say your server IP like 99.99.99.99) as "Authorized redirect URI", google want the "Authorized redirect URI" to end with a public top-level domain (such as .com or .org).

The problem is that when I want to create OAuth client ID in google, it does not accept ".test" domain for "Authorized redirect URIs". It says: Invalid Redirect: must end with a public top-level domain (such as .com or .org). Invalid Redirect: domain must be added to the authorized domains list before submitting. While it accepts .test domain for "Authorized JavaScript origins" part! I saw most of the tutorials when using socialite and google api they set these in google console. http://localhost:8000 and http://localhost:8000/callback/google and google accepts them without problem with domain and generate the key and secret but I am not using mamp and I am going to continue with valet. I would be so thankful if you guide me about what is the alternative domain for .test which works fine in valet and also google accepts it?

AIs are not capable of citing the sources of knowledge used up to the standards of the Stack Exchange network. Even when Artificial Intelligence appears to cite sources for responses, such sources may not be relevant to the original request, or may not exist at all. For Stack Overflow, this means the answer may not honestly or fairly represent the sources of knowledge used, even if someone explicitly cites the Artificial Intelligence as an author in their answer.

The diagram below walks through the social login process from start to finish.

Improved blank slate experiences: After a user signs in using a social media account, site owners have the ability to auto-suggest or auto-populate their settings with information held in their social account. This lets organizations create a first impression of convenience and encourage further use of their apps and site.

Smarter user improvements: When users sign in to an app or site using their social network, site owners can analyze data from that platform to establish user preferences. Developers can then use this insight to create customizable user experiences and build features that are in demand.

When users sign in to an app or site

What are the benefits of social login?

Password fatigue is real, and besides the inherent vulnerability of password logins, the idea of remembering yet another password puts users off registering for additional sites.

Sign-in process

Users can use multiple Identity Providers to sign in, and Okta can link all of those profiles to a single Okta user. This is called account linking. For example, a user signs in to your app using a different Identity Provider than they used for registration. Account linking can then establish that the user owns both identities. This allows the user to sign in from either account.

Identity Providers can significantly reduce sign-in and registration friction. This allows your users to easily access applications without needing to create passwords or remember usernames.

External Identity Providers

Use a single project to hold all platform instances of your app (Android, iOS, web, etc.), each with a different Client ID.

The Google Sign-In server-side flow differs from the OAuth 2.0 for Web server applications flow.

Okta supports the following enterprise and social Identity Provider types:

JSON HAL

curl -v -X POST \ -H "Accept: application/json" \ -H "Content-Type: application/json" \ -H "User-Agent: Mozilla/5.0 (${systemInformation}) ${platform} (${platformDetails}) ${extensions}" \ -H "Authorization: SSWS ${api_token}"

Indicates that the content of the element is an identifier with transient semantics and SHOULD be treated as an opaque and temporary value by the relying party.

Moreover, social logins are often implemented in an insecure way. Users, in this case, have to trust every application which implemented this feature to handle their identifier confidentially.

One such way that social media accounts are exploited is when users are enticed to download malicious browser extensions that request read and write permissions on all websites. These users are not aware that later on, typically a week or so after being installed, the extensions will then download some background Javascript malware from its command and control site to run on the user's browser.

When a user signs in, you can link the user’s Facebook account to an existing Okta user profile or choose to create a new user profile using Just-In-Time (JIT) provisioning.

It’s an unfortunate fact that many people use the same credentials to log into different accounts. This password practice is a big part of what enables account takeovers, as it increases the likelihood that hackers can use compromised credentials to access sensitive information across accounts.

As a prevention method, organizations should consider implementing passwordless practices like fingerprints or facial recognition, as well as modern authentication standards like WebAuthn, which remove passwords from the authentication experience. When organizations opt for these authentication methods, they help to mitigate the risk of stolen credentials, and minimize the chance of account takeovers.

For organizations where passwordless authentication is not yet possible, the next best option is to use adaptive multi-factor authentication (Adaptive MFA) as a security measure. This approach monitors the user’s login behavior on the basis of location, device, network, and more to determine which authentication methods to use. If the risk factor is high, then the user would be asked to submit an additional identifying factor such as an TOTP code or a one-time password.

In retail or e-commerce settings, this is particularly effective as hackers will often change details, including the shipping or email address, associated with the account. By reacting to that type of change and requesting an additional factor, adaptive MFA can better protect a customer’s sensitive data.
