I use Firebase Authentication for a React Native project
React-native: 0.44.2 Firebase: 4.1.1
Initially I'm using signInAnonymously then I retrieve the token. After I use the token for authentications (signInWithCustomToken) but I always have auth/invalid-custom-token
Does someone have an idea?
Thank you
When you signInAnonymously, you are already signed in and the ID token is not a custom token. You can't sign in with that.
If you want to make sure the session is maintained the next time the app is restarted, use:
firebase.auth().onAuthStateChanged(function(user) {
if (user) {
// User signed in. firebase.auth().currentUser is not null.
} else {
// No user signed in.
}
})
