In order to delete a new user you must be an administrator. Companies apply to add administrators by contacting Banking Circle at email@example.com. The administrator role is a separate user type that is not allowed to initiate or approve payments.
Sign into Banking Circle, then open Administration in the side bar menu
In the Administration tab, open Users
Find the user you wish to delete and find the Retire option in the table
Click Retire - and an action message will be shown: "Are you sure you want to retire <user>? Once retired the user will no longer be able to log in"
Click Retire to continue
The user deletion may need to be authenticated under Strong Customer Authentication (SCA) by using the Authy app.
Depending on your setup, the user deletion may also have to be approved by an internal approver.
