Hi - On my previous phones the Microsoft Authenticator app would pop-up a window so I could approve (or not) my sign-in. Currently on my S20 Ultra I get the message, have to unlock the phone, find and open the message then approve. Is there a way to get it so it just pops the window up?
I think it depends how the service using 2FA is configured.
Google will just check with a Yes or No for example as long as you haven't also configured it for Authenticator. I think push checks are a lot more practical than Authenicators - which normally are a real faff if you change phones!
