[PostFinance] What is a UserID?

A USERID identifies the specific user of an account.

If your account has more than one user, you log in by filling in your USERID, your PSPID (payment service provider ID) and your password. Please make sure you click on the “User login” button on the right of the login screen to make sure all three fields are displayed.

If your account only has one user, you’ll log in as a merchant using only your PSPID and password. Please make sure your login screen only displays two fields. If you can see three fields, click on the return button on the right of the log-in form to log in as a merchant.
