How do I validate access token Okta?
The high-level overview of validating an access token looks like this:
- Retrieve and parse your Okta JSON Web Keys (JWK), which should be checked periodically and cached by your application.
- Decode the access token, which is in JSON Web Token format.
- Verify the signature used to sign the access token.
What is PKCE flow Okta?
If you are building a native application, then the Authorization Code flow with a Proof Key for Code Exchange (PKCE) is the recommended method for controlling the access between your application and a resource server.
How does Okta authentication work?
Each time a user tries to authenticate, Okta will verify their identity and send the required information back to your app. Use our SDKs or API to connect your apps, add users, configure rules, customize your sign-in page, and then monitor your services from our built-in reports.
What happens when PKCe code verification fails in Okta?
This code: https://github.com/okta/okta-auth-js/blob/master/packages/okta-auth-js/lib/TokenManager.js#L123 will attempt to renew a token, which begins an authorization flow and writes new PKCE data to session storage. If this occurs on the callback route, it will overwrite the PKCE data which was saved before the redirect.
How to validate access tokens in Okta developer?
If you are validating access tokens, you should verify that the aud (audience) claim equals the audience that is configured for your Authorization Server in the Okta Developer Console. For example, if your Authorization Server audience is set to MyAwesomeApi, add this to the validation parameters:
The Authorization Server stores the hashed value (the Code Challenge) for later verification and, after the user authenticates, redirects back to the app with an authorization code. The app makes the request to exchange the code for tokens, only it sends the Code Verifier instead of a fixed secret.
How to get an access token and make a request?
Auth URL — enter the authorization endpoint for your Org Authorization Server.
