resetCustomerOneTimePassword generates a new one-time password for a web login and returns it, so you can send it to a user who forgot the password. You can reset it for your own web users and for the web users of your direct sub-customers; the root customer can reset it for any web user.
The one-time password is valid until the end of the day it was generated, by the switch’s clock. The regular password keeps working. A sign-in with the one-time password is reported by authCustomer as fault 410.
