Link a mobile number
Linking a mobile number allows you to use your mobile device for two factor authentication, which we'll cover in the next step.
To link a mobile number, click on Link Mobile Number and enter your mobile number in the field. You may have to switch the country code by clicking the flag on the left. Click on Save, and shortly after a code should be sent to your mobile device.
Once you've entered the code, your mobile number will now be verified. You can now proceed to the next step in Level 2 where you'll enable Two-Step Verification (2FA).
