What is 2 Factor Authentication (2FA)?

Two-factor authentication (2FA) is an additional layer of security to protect an account or system. Users must go through two layers of security before being granted access to an account or system. Also, 2FA increases the safety of online accounts by requiring two types of information from the user, such as a password or PIN, an email account, an ATM card or fingerprint, before the user can log in. The 2FA is designed to prevent unauthorized users from gaining access to an account with nothing more than a stolen password.

Our patented process verifies the person’s ownership of the remotely presented payment instrument. Paydentity then dynamically links a 2FA process to the verified card, to secure future payments.
