Firebase says "Domain not whitelisted" for a link that is whitelisted

Question

I am busy setting up a firebase authentication using an email magic link and using the guide here:

https://firebase.google.com/docs/auth/android/email-link-auth

It says I need to whitelist a domain, but I cannot find any place in the console to do that, other than the dynamic link I created. I tried running the below code, but I get

[ UNAUTHORIZED_DOMAIN:Domain not whitelisted by project ]

    val actionCodeSettings = ActionCodeSettings.newBuilder()             // URL you want to redirect back to. The domain (www.example.com) for this             // URL must be whitelisted in the Firebase Console.             .setUrl("https://myapphere.page.link/register") //I created this dynamic link in the firebase console             .setHandleCodeInApp(true)             .setAndroidPackageName(                     "com.myapphere",                     true,                      "1")             .build()      val auth = FirebaseAuth.getInstance()     auth.sendSignInLinkToEmail(email, actionCodeSettings)             .addOnCompleteListener(this) { task ->                 if (task.isSuccessful) {                     // Sign in success, update UI with the signed-in user's information                 } else {                     // If sign in fails, display a message to the user.                 }             } 

Am I not supposed to use dynamic links for firebase authentication? And if so, where in the console do I whitelist domains, because I cannot find it.

Answer 1

1. Go to Firebase Console
2. Click Authentication Menu > Sign-in method tab
3. Scroll Down to Authorized domains
4. Click "Add domain" button, add your domain (website domain with parameter) and click "Add"

Answer 2

I had the same problem, the reason was my SHA-1 key configured in Firebase was wrong.
