When we use default Auth providers like Google, Facebook, Email. But in custom authentication, Firebase SDK need to contact 3rd party server to fetch new token. Here only SDK is failing to refresh the token!

Historical background

My workaround is, maintain a "last-token-fetch-time" info at local on every successful token fetch, so that we can refresh the token manually after one hour. It can be a maximum of seconds later than the iat. Note: this only controls the time when the custom token itself expires. But once you sign a user in using signInWithCustomTokenthey will remain signed in into the device until their session is invalidated or the user signs out. As document says, custom JWT token is valid for max 1Hr; so before it expires, authenticate your user with Firebase.

After that session will remain active; It wont expire! Once you are signed in and your Firebase Admin account and app configuration is setup correctly, the SDK can communicate back and forth with the Firebase back-end to keep the tokens up to date.

I come across this error few times every day out of some times. Started facing this issue after I upgraded the client side code to use Firebase 3. I have a similar issue.

So, I think that token is valid, but for some reason login fails. I've figured out the problem in my case.

About Xamarin Xamarin.Use this level to complete administrative tasks that have well-defined access requirements.

For example, when running a summarization job that reads data across the entire database, you can protect against accidental writes by setting a read-only security rule and then initializing the Admin SDK with privileges limited by that rule. At a minimum, you need to provide a uid, which can be any string but should uniquely identify the user or device you are authenticating. These tokens expire after one hour. You can also optionally specify additional claims to be included in the custom token.

If a Firebase client app communicates with your server, you might need to identify the currently signed-in user. To do so, verify the integrity and authenticity of the ID token and retrieve the uid from it. You can use the uid transmitted in this way to securely identify the currently signed-in user on your server.

See if those solve your problem before verifying ID tokens yourself. See Auth tokens for more information. Auth::verifyIdToken accepts the following parameters:.

A leeway of 5 minutes is applied when verifying time based claims starting with release 4. This method will create a new user in the Firebase Auth User Database each time it is invoked. IdP Identitiy Provider credentials are credentials provided by authentication providers other than Firebase, for example Facebook, Github, Google or Twitter.

Once you have received those credentials, you can use them to sign a user in with them, for example with Twitter:. This will revoke all sessions for a specified user and disable any new ID tokens for existing sessions from getting minted. Existing ID tokens may remain active until their natural expiration one hour. If the check fails, a RevokedIdToken exception will be thrown.

For this reason, performing this check on your server is an expensive operation, requiring an extra network round trip. You can avoid making this network request by setting up Firebase Rules that check for revocation rather than using the Admin SDK to make the check.

Note A leeway of 5 minutes is applied when verifying time based claims starting with release 4. Note Not all sign-in methods return all types of tokens. Read the Docs v: stable Versions latest stable 5.Apigee Edge provides the OAuth 2.

OAuth2 is one of the most popular open-standard, token-based authentication and authorization schemes. It enables client applications to access APIs on behalf of users without requiring users to divulge their username and password.

Client applications use access tokens to consume secure APIs. Each access token has its own expiry time, which can be set in the OAuthv2 policy. Refresh tokens are optionally issued along with access tokens with some of the grant types. Refresh tokens are used to obtain new, valid access tokens after the original access token has expired or been revoked. The expiry time for refresh tokens can also be set in the OAuthv2 policy.

The following example OAuthV2 policy shows a long expiration time of days for refresh tokens:. Use an appropriate lower expiration time for OAuth access and refresh tokens depending on your specific security requirements, so that they get purged quickly and thereby avoid accumulation. Set the expiration time for refresh tokens in such a way that it is valid for a little longer period than the access tokens.

For example, if you set 30 minutes for access token and then set 60 minutes for refresh token. Except as otherwise noted, the content of this page is licensed under the Creative Commons Attribution 4. For details, see the Google Developers Site Policies. Apigee Edge Private Cloud Latest v4.
