Multifactor Authentication (MFA) Initial Setup with Text Messages

Multifactor authentication (MFA), also known as two-factor authentication (2FA), is a feature which allows users to better protect their account by requiring additional steps when signing in. MFA increases security on your account by requiring you to first sign in using your username and password, then approve the sign in request using a second factor like your mobile phone.
