# Multifactor authentication

Learn how to keep your account safe by setting up multifactor authentication.

[View source](/account/multifactor-authentication.md)

All users with an Adyen Customer Area account must set up Multifactor Authentication (MFA) or [Single Sign-On](/account/single-sign-on/) in the [Customer Area](https://ca-test.adyen.com/).

MFA keeps your account secure by requiring an additional form of verification in order to log in. This prevents unauthorized users from accessing your account, even if they have obtained your username and password.

Each user can set up one authentication method per device and register two devices through MFA. If you have the **Merchant admin** role, you can:

* See user details by going to **Account** > **Users**.
* [Manage user access](#manage-devices) by removing devices registered to users in your organization.

In your [Customer Area](https://ca-test.adyen.com/), you have two ways to set up MFA for your account:

* With an [authenticator app](#authenticator-app), such as Google Authenticator, Okta Verify, or Microsoft Authenticator, which generates time-based one-time passwords on your mobile device.
* With [SMS authentication](#sms-authentication), which sends SMS messages with time-based one-time passwords on your mobile device.

## Requirements

Before you begin, take into account the following requirements and limitations.

| **Limitations**      | SMS authentication is only available in the live environment.                                                          |
