# Multifactor Authentication (MFA)

The usage of Multifactor Authentication (MFA) helps users add an additional layer of security above and beyond their [initial sign-in mechanism](/admin/sign-in-and-mfa/sign-in-methods.md).  

Abbey supports the following MFA methods: 

* **Authenticator Apps:** These include Google Authenticator, Duo, and others. These apps generate a one-time code that the user then inputs into Abbey on sign-in. 
* **Backup Codes:** A user can generate a list of unique codes they can save and use once. 

It is currently configured on a per-user basis and is optional. A user can configure MFA by selecting their profile within the Abbey application, and clicking **Manage Account**.

Under **Security**, they then select **Add two-step verification**, and complete the registration flow for a new factor.&#x20;
