If you encounter "passwordToken is not allowed" when trying to create / reset a password, then it means there's already an open connection to Sightcall Console somewhere in the computer that's preventing the password creation / reset process. This typically happens when you have one browser tab already logged in to SightCall console either directly or via integrated environment (Salesforce, Zendesk, etc.), and another browser tab is attempting to create / reset a password.
To fix this issue, you will need to logout from SightCall console or from the integrated environment, close all browser tabs, open a new browser tab and try to create / reset the password again.
A cache refresh might be necessary.
