Two-Step Authentication Which do you prefer?

After a couple of cups of coffee this morning I decided to see what this OneDrive Personal Vault was all about. I'll address that at a later date! When signing in, it asked me to authenticate, and gave me 4 choices. 1: Text (***) (***)-**22 < Not Real 2: Approve a request on my Microsoft Authenticator app. 3: Use a verification code from my mobile app 4: email $%#@ID10T error.com< again Not Real So which boys and girls and children of all ages, do you prefer/use, and Why?
