I want to add another registered phone. I have forgotten my pin. How do I get a new one?
Log into your account on the Skype web site. You can click on "Account" in the upper-right corner of this page. Then click on Skype To Go Number when you are in your account, and look to the right to see "PIN Change from time to time for safety Edit". Click on the word Edit, and you should be able to reset your PIN.
Right above that line with the PIN is where you can manage the phones that are registered to your Skype To Go number. Click on the Manage link to see those numbers.
