Additional Information

Additional Information: 

Multifactor authentication ("MFA") uses multiple proofs of identity to ensure you are authorized to access the service or resource that you are requesting. These proofs include something you know (a secret like a password), something you have (a token, card or device), or something you are (a biometric measurement or representation).

Duo is a service that can use a mobile app, a text message or a phone call to authenticate you. It can be combined with other authentication factors like username and password authentication to create multifactor authentication. Most people use Duo via the mobile app, Duo Mobile, which runs on a variety of smartphones and tablets.
