Two-factor authentication (2FA)

Two-factor authentication (2FA) is a way to improve security, and prevent unauthorized persons from accessing user accounts.

Practically, 2FA means storing a secret inside an authenticator, usually on a mobile phone, and exchanging a code from the authenticator when trying to log in.

This means an unauthorized user would need to guess the account password and have access to the authenticator, which is a more difficult proposition.
