what I want actually is,
Currently, I log in to my app using an account using email ID and password, and OTP for 2FA.
email ID which im using for login supports TOTP.
so can I add the user's account into an authenticator apps like Google, Microsoft authenticator,
which will give me a unique key every time and by entering that key in my app it will validate the user and let him log in.
i want to remove my existing phone based OTP flow.
