Multi-factor authentication (also Two-factor authentication, TFA, T-FA or 2FA) is an approach to authentication which requires the presentation of two or more of the three authentication factors: a knowledge factor (“something the user knows”), a possession factor (“something the user has”), and an inherence factor (“something the user is”).

Multi-factor authentication is a key benefit in a translation management system (TMS) for the security of sensitive corporate documentation.

Secure TMS platforms also have access level control, finger print authentication, SSL certification as well as encryption.
