# How to set up and enable Two-factor authentication (2FA) on Ace Public Cloud?
Learn how to set up and enable two-factor authentication (2FA) on Ace Public Cloud.
**Step 1:** [Login](https://customer.acecloudhosting.com/index.php?rp=/login) into your account.
**Step 2:** Navigate to the **Profile** section and select **Security Settings.**
**Step 3:** Select the **Two-Factor Authentication** tab.
**Step 4:** Hit **Click here to Enable**.
**Step 5:** You can set 2FA using two methods, **Time Based Tokens** and **SMS Center Two-Factor Authentication**. Select your desired method and click on **Get Started**.
**A.** If you choose **Time Based Tokens,** you have to download an authenticator application like [Google Authenticator](https://apps.apple.com/gb/app/google-authenticator/id388497605) or [Duo](https://apps.apple.com/gb/app/duo-mobile/id422663827).
After downloading the app, scan the QR code or enter the code manually in the application.
After scanning, it generates a security code, enter it, and hit **Submit** button.
Now if you enter the correct security key, your 2FA will enable successfully, and a Backup code will generate, which will be needed in the event when [you cannot complete 2FA](https://customer.acecloudhosting.com/index.php?rp=/knowledgebase/26/I-am-unable-to-login-using-Two-Factor-Authentication-2FA-what-should-I-do-now.html).

**Note:** Time-based Token every time generates a new security code, enter it whenever you are login into your account.
{% endhint %}
**B.** If you choose **SMS Center Two-Factor Authentication**, then you have to enter your mobile number to receive the security key on the text message and click on **Activate**.
Enter the code received on your mobile and hit **Activate**.
On entering the correct security key, your 2FA will enable successfully, and a Backup code will generate, which will be needed in the event when [you cannot complete 2FA](https://customer.acecloudhosting.com/index.php?rp=/knowledgebase/26/I-am-unable-to-login-using-Two-Factor-Authentication-2FA-what-should-I-do-now.html).
