PERTAIN_TORootCause

checks it is not expired — The utility API looks up the nonce in its database. Tension: then enables issuance of a token for Site B. Outcome: then removes its database row.

PERTAIN_TOProblem

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

PERTAIN_TOProblem

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

PERTAIN_TOSolution

Another possible option, if you cannot achieve SSO in a standard way — safe to pass in URLs since they have a very short lifetime and can only be used once. Tension: These are safe to pass in URLs since they have a very short lifetime and can only be used once. Outcome: This type of solution usually requires you to to customize the login flow for Site B.

PERTAIN_TOSolution

Ideally, use a standard protocol like OAuth 2.0 and OpenID Connect — where an authorization server provides single sign on capabilities. Tension: to enable the above.

PERTAIN_TOProblem

Is it a good idea to make a call to the authorization service for every request? — a "one-per-request" filter to the main service. Tension: to call the authorization service, check the JWT, and get user information from it. Outcome: in the future, to all other services.

PERTAIN_TOProblem

How can I get the authenticated user in the main service? Tension: In a monolithic application, I would save it in the SecurityContextHolder in a "one-per-request" filter. Outcome: Should I add a "one-per-request" filter to the main service.

PERTAIN_TOProblem

there is an endpoint in the main service that needs to be secured not only by a valid JWT — in the main service. Tension: but also by the roles that the authenticated user has. Outcome: configure secured endpoints for each service?

PERTAIN_TOSolution

the information about the user is inside the JWT — other services does not need to call the authorization service or database. Tension: this token is signed from the authorization service but other services does not need to call the authorization service or database. Outcome: they only need a shared secret they use to check the validity of the token.

PERTAIN_TOProblem

all requests to `Firebase` are blocked — It works on debug but not on release. Tension: Error getting App Check token; using placeholder token instead. Error: n8.j: Error returned from API. code: 403 body: App attestation failed. Outcome: everything works now.

PERTAIN_TOProblem

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.

PERTAIN_TOSolution

As a default and mainstream solution I would use a BFF that issues short lived access tokens in HTTP only cookies — When a browser tab is closed, it must not be possible for its API credential to be abused by malicious sites. Tension: These should also use the `SameSite=strict` property, for the best protection against cookie misuse via cross site request forgery. Outcome: These should also use the `SameSite=strict` property.

PERTAIN_TOProblem

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.

PERTAIN_TOSolution

Possible Fix — Given your setup with Expo and `firebase/auth`. Tension: the refresh token mechanism might not be working as expected on your web build. Outcome: Firebase Auth's persistence is configured.
