The verification implemented well, and i get the relevant email, but even when
i do not click on verification link, i succeed to login to my app.



How can i fix it, please?



My verification implementation is like this:



final FirebaseUser user = mAuth.getCurrentUser();

if (user.isEmailVerified())

Toast.makeText(this, "Email is verified", Toast.LENGTH_SHORT).show();
else

Toast.makeText(this, "Email is not verified", Toast.LENGTH_SHORT).show();
user.sendEmailVerification()
.addOnCompleteListener(this, new OnCompleteListener()
@Override
public void onComplete(@NonNull Task task)
// Re-enable button
// findViewById(R.id.verify_email_button).setEnabled(true);

if (task.isSuccessful())
Toast.makeText(AccountTypeActivity.this//EmailPasswordActivity.this
,"Verification email sent to " + user.getEmail(), Toast.LENGTH_LONG).show();
else
Log.e(TAG, "sendEmailVerification", task.getException());
Toast.makeText(AccountTypeActivity.this//EmailPasswordActivity.this
, "Failed to send verification email.",
Toast.LENGTH_LONG).show();


);

          • Make sure you enforce access for verified emails in your server or security rules. Front end validation is not enough.
