   If you’re on your phone, select the three dots in the top right of the screen, then Profile

   Your Customer ID is on this screen. If you've chosen your own username and want to check your Customer ID:
   • Go to Edit under Customer ID / Username
   • Select and delete your Username
   • Your Customer ID will show 
   • Choose Cancel to keep your username, or choose Apply to go back to using your Customer ID to log in. 
3. To choose your own username, select Edit under Customer ID / Username
4. Type the username you’d like to log in with, then Apply.
   Your username must
   • Be between 4-20 characters
   • Have at least one letter
   • Use letters and numbers only (not have any spaces or special characters

   • Be unique - if someone else if already using that name, you'll need to choose another. Don't reuse one you're already using to log into another account
5. Log in next time with your new username, or use it to reset your password. Take a minute to check we’ve got the right phone number for password resets.
