ID Tokens (2024)

FAQs

How to easily obtain a Google ID token? ›

ID tokens are private to the client and should never be sent to APIs. Access tokens are also received by clients, who treat them as opaque strings and send them as message credentials when calling APIs.

The ID token is a security token that includes claims regarding the authentication of the user by the authorization server with the use of an OAuth client application.

ID token lifetime

By default, an ID token is valid for 36000 seconds (10 hours).

Access tokens are meant to be read by the resource server. ID tokens are JWTs. Access tokens can be JWTs but may also be a random string. ID tokens should never be sent to an API.

ID token lifetime

ID tokens are valid for up to 1 hour (3,600 seconds).

To get an ID token , you need to request them when authenticating users. Auth0 makes it easy for your app to authenticate users using: Quickstarts: The easiest way to implement authentication, which can show you how to use Universal Login, the Lock widget, and Auth0's language and framework-specific SDKs.

They can both be encoded as JWT, but the content and purpose are also different. An ID token contains the identity information about the authenticated users, and it is intended to be consumed by the front-end application. On the other hand, an access token represents a ticket with permission to consume an API.

We recommend against storing ID tokens. If you must do so, ensure that you clear the tokens when users log out or delete accounts. In contrast to traditional web apps, single-page applications (SPAs) require client-side API calls to process user interactions.

How to validate Google id_token? ›

Solution: when we exchange the code to get access token, we will be receiving two jwt token in response (access_token, id_token). In that two tokens use id_token, which is you're id_token_hint.

ID tokens are a type of security token that serves as proof of authentication, confirming that a user is successfully authenticated. Information in ID tokens enables the client to verify that a user is who they claim to be, similar to name tags at a conference.

The FAPI 1.0 baseline profile recommends that any ID tokens received on the front channel are encrypted, such as when using the Hybrid Flow. This prevents any Personally Identifiable Information (PII) from being revealed to the browser or written to server logs.

Once issued, access tokens and ID tokens cannot be revoked in the same way as cookies with session IDs for server-side sessions. As a result, tokens should be issued for relatively short periods, and then refreshed periodically if the user remains active.

The id_token is issued only for client which requested it (it is called Relying Party). You should not send this token to any other parties (clients or resources). From my experience I have short lived identity tokens (5 minutes). I validate this and confirm the user is correct (extract "sub" and validate the token).

You can refresh access and ID tokens using the /token endpoint with the grant_type set to refresh_token . Before calling this endpoint, obtain the refresh token from the SDK and ensure that you've included offline_access as a scope in the SDK configurations.

API keys are typically associated with specific servers the calling application is deployed on. When the application makes an API request, the server identifies the calling application by the API key. In contrast, an API token is a string of codes containing comprehensive data that identifies a specific user.

Beyond what is required for JWT , ID tokens also contain claims asserted about the authenticated user, which are pre-defined by the OpenID Connect (OIDC) protocol, and are thus known as standard OIDC claims. Some standard OIDC claims include: name. nickname. picture.

Obtaining Access Token and Refresh Token

Navigate to OAuth 2.0 Playground and click the OAuth 2.0 Configuration button in the top right corner of your screen. Select Use your own OAuth credentials, and provide the obtained Client ID and Client Secret values. Click on Close.

You can generate an IAM token by using either your IBM Cloud API key or a service ID's API key. The API key is a permanent credential that can be reused if you don't lose the API key value or delete the API key in the account.
