Accessing credentials

Amplify Android v1 is now in Maintenance Mode until May 31st, 2024. This means that we will continue to include updates to ensure compatibility with backend services and security. No new features will be introduced in v1.

Please use the latest version (v2) of Amplify Library for Android to get started.

If you are currently using v1, follow these instructions to upgrade to v2.

Amplify libraries should be used for all new cloud connected applications. If you are currently using the AWS Mobile SDK for Android, you can access the documentation here.

An intentional decision with Amplify Auth was to avoid any public methods exposing credentials or manipulating them.

With Auth, you simply sign in and it handles everything else needed to keep the credentials up to date and vend them to the other categories.

However, if you need to access them in relation to working with an API outside Amplify or want access to AWS specific identifying information (e.g. IdentityId), you can access these implementation details by casting the result of fetchAuthSession as follows:

1Amplify.Auth.fetchAuthSession(
2    result -> {
3        AWSCognitoAuthSession cognitoAuthSession = (AWSCognitoAuthSession) result;
4            switch(cognitoAuthSession.getIdentityId().getType()) {
5                case SUCCESS:
6                    Log.i("AuthQuickStart", "IdentityId: " + cognitoAuthSession.getIdentityId().getValue());
7                    break;
8                case FAILURE:
9                    Log.i("AuthQuickStart", "IdentityId not present because: " + cognitoAuthSession.getIdentityId().getError().toString());
10            }
11        },
12        error -> Log.e("AuthQuickStart", error.toString())
13);

1Amplify.Auth.fetchAuthSession(
2    {
3        val session = it as AWSCognitoAuthSession
4        when (session.identityId.type) {
5            AuthSessionResult.Type.SUCCESS ->
6                Log.i("AuthQuickStart", "IdentityId = ${session.identityId.value}")
7            AuthSessionResult.Type.FAILURE ->
8                Log.w("AuthQuickStart", "IdentityId not found", session.identityId.error)
9        }
10    },
11    { Log.e("AuthQuickStart", "Failed to fetch session", it) }
12)

1try {
2    val session = Amplify.Auth.fetchAuthSession() as AWSCognitoAuthSession
3    val id = session.identityId
4    if (id.type == AuthSessionResult.Type.SUCCESS) {
5        Log.i("AuthQuickStart", "IdentityId: ${id.value}")
6    } else if (id.type == AuthSessionResult.Type.FAILURE) {
7        Log.i("AuthQuickStart", "IdentityId not present: ${id.error}")
8    }

10    Log.e("AuthQuickStart", "Failed to fetch session", error)
