Multi–factor authentication is an authentication method in which a computer user is granted access only after successfully presenting two or more pieces of evidence (known as factors) to an authentication mechanism: knowledge (something the user and only the user knows), possession (something the user and only the user has) such as sending a passcode through to a registered phone number as part of the account access.
Multi-factor authentication greatly reduces the risks associated with lost VPN login credentials, but existing MFA solutions are often too complex or inconvenient for users. Cisco Duo Security has solved this challenge for more than 12,000 global customers with authentication solutions for businesses of every size.
