AT&T MFA app for iPhone and iPad

AT&T MFA is AT&Ts secure multi-factor authenticator that significantly improves both business and personal account login security.

AT&T MFA takes phone-based multi-factor authentication to the next level by turning your phone into a FIDO2 authenticatore. This app leverages the FIDO2/WebAuthn strong authentication standards to deliver a ""phish-proof"" push with a delightful and simple user experience. AT&T MFAs FIDO2 solution works with both our business offering and most consumer websites that support FIDO2 security keys (like facebook.com, twitter.com, google.com, github.com, and many more).

Additionally, AT&T MFA can generate one-time passcodes for offline access login and can receive regular push notifications for traditional tap-to-approve on iOS devices.

Note: To use with AT&Ts authentication service you need to first enroll; contact your organizations help desk.
