I stopped other 3rd party authenticator apps I kept using Google Authenticator which doesn't ask for a phone number or email you can use it without them just make sure you separately save your backup codes to a safe place so that you can use them in other app or use it for recovery purposes.

Authy is not the best authenticator since before their data always got breached and it isn't safe anymore to use in any exchange accounts.

Look at the old news about this below
