# Multi-factor Authentication

Multi-factor Authentication (MFA) requires a second authentication factor in addition to user name and password sign-in credentials, which adds extra security for your account. With MFA enabled, you'll confirm your identity using both your password and your authenticator app. Therefore your account resources will be more secure.

You need to install an authenticator app compliant with the Time-based One-time Password (TOTP) algorithm and supported multiple tokens. You must type a valid verification code from your authenticator app during sign-in.

## Prerequisites

* You have installed an authenticator app compliant with the Time-based One-time Password (TOTP) algorithm and supported multiple tokens on your device.
* Each authenticator app assigned to a user must be unique. You can't type a verification code from other's MFA device to authenticate.
* Currently supported MFA authenticator apps for both Android and iOS systems:\
  Twilio Authy Authenticator, Duo Mobile, Microsoft Authenticator, Google Authenticator

1. Sign in to [zenConsole](https://console.zenlayer.com/dashboard) and go to <img src="/files/OpBVTu9w6b4cLMhp1sjt" alt="" data-size="line"> > **Profile Settings** > **Enable MFA**.
2. Open your authenticator app and scan the QR code. Alternatively, you can type a secret key.<br>

3. After scanning the code, you will get a one-time password code on you authenticator app. Fill in MFA code from your authenticator app and MFA will be activated automatically.\
   Here we take the Microsoft Authenticator page as an example.
