# Configuring Two-Factor Authentication

Two-Factor Authentication (2FA) is a security feature that adds an additional layer of protection to Welkin user accounts.

To enable Two-Factor Authentication:

* Log into Admin
* Click on 'Settings' in the left vertical menu
* Select the 'Security' tab
* Under 'Two-Factor Authentication', toggle the setting to 'On'
* Click 'Save'

When 2FA is enabled, users will be required to provide an additional verification code when logging in. This code is typically sent via SMS, email, or generated by an authenticator app.

To make 2FA optional instead of required:

* Follow the steps above but toggle to 'Optional'

**Note:** When 2FA is enabled, users should be informed of this change so they can set up their preferred 2FA method.
