You might want to verify your phone number after creating your account to enable two-factor authentication (2FA). Here's how you can verify your phone number if you didn't create your account using your phone number.

1. Log in to your account, hover over your username on the top right of the page and click Settings from the context menu that appears.
2. The Settings page will appear and on the menu on the left side of the page, click Profile.
   
3. Enter your phone number in the PHONE field and click Verify or Use a phone call instead.
   

   Note: We recommend the Verify option as the call option is not supported in all countries.

4. a) Phone call option
       You will receive a phone call with the numeric confirmation code. Listen carefully to the code and enter it in the field below and click Submit. 
   b) Verify (SMS) option
       You receive an SMS with the numeric confirmation code. Enter the code in the field below and click Submit. 
   
   Your number is now successfully verified!
   
   After confirming your phone number, consider activating 2FA and verifying your ID.
