Hi ​@stest07

Welcome to Box Community, and we’re glad to assist! 

 

To enable SMS multi-factor authentication for your individual account:

Note

Your Box administrator may not allow SMS as an authentication method. If so, this option will not be available to you.

  1. Go to Account Settings > Account.
  2. In the 2-Step Verification section, click Set Up.
  3. Select SMS Text Message and click Next.
  4. Enter your phone number and click Continue. Some countries do not support 2FA via SMS.
  5. Enter the code you received as a text message and click Submit.
  6. Copy the backup codes. Once copied, paste them into a file only you have access to and save the file somewhere secure.
  7. Click Complete.

 

Hope it helps! If you have additional questions, please let us know.
