Multi-factor authentication (MFA), also known as two-factor authentication (2FA), is now the industry-standard solution for keeping your accounts safe—and for good reason. It feels like every week there’s another report of a data breach exposing thousands or millions of usernames, passwords, and other personal identifiable information (PII). If you’ve ever reused a password, multiple accounts could be in danger of unauthorized access from a single data breach. MFA helps keep accounts secure even if a password has been compromised.
