# Two-factor Authentication

## 
## What Is Two-factor Authentication? 
Two-factor authentication is a quick and easy way to secure your Nexudus account. After logging in using their email and password, admins are asked to enter a code they receive on their phone before they can access the {{variable.AdminPanel}}. 

This additional step ensures only you can access your account and reduces the risk of your account being hacked.

## How Two-factor Authentication Works

All you need to use two-factor authentication is an authenticator app on your phone. You can use any TOTP-based authenticator app, such as **Google Authenticator**  that is available on [iOS](https://apps.apple.com/us/app/google-authenticator/id388497605){target="_blank"} and [Android](https://play.google.com/store/apps/details?id=com.google.android.apps.authenticator2){target="_blank"}. 

Once you have the app on your phone, you can [enable two factor authentication](/v3/docs/enabling-two-factor-authentication){target="_blank"} in your account in a few easy steps. 

:::(Info) (You cannot enable two-factor authentication in bulk. )
Each admin must enable two-factor authentication from their own account.

## FAQ

### Can I enable two-factor authentication for a colleague? 
No. Two factor authentication relies on connecting a user's device (usually their phone) to their admin account in Nexudus. 

### I don't have access to my phone and I can't log in without two-factor authentication, what do I do?

If you haven't added a backup device to your Authenticator app, you can get in touch with us at [support@nexudus.com](http://mailto:support@nexudus.com){target="_blank"}. We'll disable two-factor authentication for you and you'll be able to log in again. 
We strongly recommend [adding at least one backup device](/v3/docs/adding-a-backup-device){target="_blank"} to your authenticator app to avoid this issue.
