# Logging in and 2FA

{% hint style="info" %}
**What is 2FA?** 

Two-factor authentication (2FA) is an authentication method that provides an additional layer of security. It is also known as two-step verification.

Unlike single-factor or password based systems which only ask users for their username and password, 2FA requires the user to provide one more verification factor to log in to an account or system
