AT&T MFA

AT&T MFA is AT&T's 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 MFA's 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&T's authentication service you need to first enroll; contact your organization's help desk.
