On the **Microsoft Authenticator** main page, tap the **plus icon** at the top. There are three types of accounts that can be added: **Personal Account**, **Work or School Account**, and **Other Accounts (Google, Facebook, etc.)**. You should select **Other Accounts (Google, Facebook, etc.)**. There are two methods to add an account in **Microsoft Authenticator**:

1. Scan QR Code&#x20;

If you select **Other Accounts (Google, Facebook, etc.)**, you will automatically be directed to the **Scan QR Code** page. Point your camera at the saved QR Code.

2. Enter code manually&#x20;

If you do not have the QR Code saved, you can tap the **Enter code manually** button on the **Scan QR Code** page. This will open the **Add Account** page, where you need to enter the **Account Name** and **Secret Key** that you obtained when activating Multi-Factor Authentication in the **Deka GPU Portal Service**.
