Where can I find my login credentials for the queues?

On the "My Queues" page, you can view your login credentials for all your active queues. Depending on the queue, either your personal identity number or your email address is used as the username.

For family accounts:
If you have a family account, you can also view the login credentials for all sub-accounts. Switch to the profile you want to view to see the specific credentials for that family member.
