Token Type Mismatch

token-type-mismatch

JWT access/refresh (or opaque) tokens get validated and revoked as if they share one interchangeable format because token creation, middleware validation, and lookup/revocation logic disagree on token type, breaking auth or enabling tokens to be used across apps.

Axios requests need to work on both client and server in Next.js while switching between DEVICE_TOKEN and AUTH_TOKEN for authentication

AADSTS9002325: Proof Key for Code Exchange is required for cross-origin authorization code redemption. Tension: redirects uris not matching.

in my react application I get a `403 Forbidden error` — the token is decrypted, but in my react application. Tension: Токен не найден в куки. Outcome: You could remove `dependencies=[Depends(JWTBearer())]` and that should work fine.

can use ouath2 and json web tokens to create login for users — FastAPI oauth2 + jwt extend exp time at every request. Outcome: response.headers["bearer-refreshed"] = access_token.

FastAPI returns 401 with JWK public Attribute for authorization token not found

"invalid input syntax for type uuid" — I'm building a Next.js application using Better Auth for authentication and Supabase as the database. Tension: Better Auth is generating UUIDs in a non-standard format (KZMw0N5rJhdi_i1JbWle6), but Supabase requires UUIDs in the standard format (50928f86-1dbc-4b4a-8377-c83c81051f7c). Outcome: This is causing user creation to fail.

nothing is modified and 0 rows are returned — with the following RLS rules. Tension: the authentication check `( auth.uid() = user_id )` doesn't match up when using the JWT. Outcome: I think I need to pass the JWT to the `supabase` client as well.

you should use the same secret in both places. Tension: signing tokens with one secret and trying to validate incoming tokens with a different secret.

Each application should gets its own token for data access. Tension: with its own access to resources.

Avoid passing tokens in URLs. Tension: tokens can leak to logs and be exploited.

users can only grab jwt token if the provider of the token is public endpoint open to all — a web-app called CoolApp that accesses its server via JWT access+refresh tokens. Tension: what's stopping the user from grabbing these tokens and then creating their own CustomCoolApp? Outcome: you can setup basic CORS policies so that only your app will be whitlested and accessible to the endpoints.

Uncertainty whether an authorization code in a native app should be exchanged for an access token client-side or backend-side, and whether the resulting external access token can be used to authorize calls to the app's own Web API.

how do I see whether it's an access token or an ID token? — Given a JWT token (OIDC) issued by Microsoft identity platform. Tension: I don't want the check to rely on assumptions.

Refresh tokens are typically long lived. — With our mobile applications, the product requirement is that we must provide a native/in-app login experience for Android/iOS. Tension: Is there a way for me to hook into the refresh token usage to check if my user's password has expired before issuing them a new access token? Outcome: setting UpdateAccessTokenClaimsOnRefresh = true.

Open service that returns a username from a JWT — Sending your JWT to an "open" service. Tension: that extra network trip provides no value. Outcome: Get rid of it.

Confusion about cookie authentication versus token authentication

it is also required to "forget" the token right after exiting/closing the app — I have a web API which uses JWT tokens for accessing resources. Tension: The issue with (1) is that it's not cleared when a browser's tab is closed but only when all the windows are. And (2) is not secure since if an attacker manages to inject a code into a client he will be able to extract the access token.

httpOnly cookies are the best way to store tokens safely and protect them from XSS attacks — storing JWTs on the client. Tension: JavaScript won't be allowed to read httpOnly cookies. How would the client handle routes authentication? Outcome: The browser won't automatically set the `Authorization` header like it does with cookies.

Need a standard way to tell which OAuth flow created an access token

Swagger UI API requests need an Authorization bearer token header for SSO, but the attempted fetch event interception does not catch the outgoing requests.

Invalid tokens are rejected. — the back uses its public key to verify the token was issued by itself. Tension: what is the point of ensuring the back was the legit issuer of the token? Outcome: it really doesn't serve any additional purpose here.

refresh token can be stolen the same way as access token

inspect their networking to view and copy such jwt token — download a legitimate app and inspect their networking. Tension: This jwt token can then be plugged in to any other app i.e a localhost server and combined with projectid etc... to perform requests that look legitimate.

workspaceId claim won't be updated until the token has been refresh — put workspaceId in the jwt claims. Tension: the drawback of this solution. Outcome: another solution that is to implement a service that query data from workspace-service and use it to validate.

I'm logged out, this happens consistently. — After being logged out I can see in the network tab that a request to google's identitytoolkit, the payload is my idToken, and the response. Tension: is of status code 400 with the TOKEN_EXPIRED error. Outcome: Firebase Auth's persistence is configured.

BearerTokenAuthenticationFilter of second chain did not activate

Spring Authorization Server persistently stores OAuth2Authorization objects that include both JWT access tokens and refresh tokens. The user questions why access token values need to be stored when JWTs are self-contained and should not require server lookups per request.

after change password I'm unable to create access and refresh token using JWT — verifying the user OTP to change password.

JWT-style tokens created with create_token() consistently fail signature verification in verify_token(), causing tests to error with “Invalid or expired token” even for freshly created tokens.

Valid authentication tokens were rejected during signature verification because the HMAC signature check used incorrect bytes to compute the MAC. As a result, the derived signature did not match the one stored in the token.
