  6. After entering the code, you will be informed that you have successfully verified your SMS and that your phone is now registered.

There are three other verification methods available; please see the articles below for details. 

Multiple MFA verification methods recommended

It is recommended that you set up at least two MFA methods, so you have a backup if one fails. Please see Adding Additional Verification Methods for Multi-Factor Authentication for instructions on setting up additional method(s). To change your default method, see Change the Default Method for Authenticating with MFA.
