  3. Tap on your work email account.
  4. Tap on “Re-enter password”.
  5. You should now see a password prompt similar to the one you see on your computer, please enter your password, and then the code you receive via text message.


  • If you don’t have a smartphone you can select ‘Authentication Phone’ and enter your mobile number (make sure to remove the leading zero) to receive a text or call as verification although this method isn’t as secure.
