Add security to your website with a one-time password system.
Two-factor authentication is a system in which two different factors are used in combination to authenticate a user. Two factors, as opposed to one factor, will deliver a higher level of authentication assurance. The combined factors could consist of:
• Something the user knows (password or pin)
• Something the user possesses (smartcard, PKI certificates, RSA SecurID)
• Something the user is or does (fingerprint, DNA sequence)
