WiscChat - How do I change my password?
WiscChat uses your NetID or Office 365 service account credentials. If you decide to change this password, you are also changing the account's password for mail and calendar.
You cannot change your password via a WiscChat client. You must use the appropriate account administration tool.
Select the account type you are using for your WiscChat account:
Note: Once you have changed your account password, you may need to update the saved password in whatever WiscChat client you are using, if you chose to save the password.
