Add and extra layer of protection with two factor authentication (2FA).

By using both a password and a PIN code from a trusted device, like a smartphone, 2FA adds layers of login security to the account. This helps with preventing brute-forcing passwords, or if your password gets leaked/exposed/found from another site, if you use the same password on multiple systems.

In simple terms, two-factor authentication prevents unauthorized users from accessing the system because they are very unlikely to have both variables to access the account. The password and PIN are needed to login. The PIN is sent to the mailbox owner’s smartphone, through something like the Google Authenticator app. If either variable is missing, access is denied.
