Try this:
Reseting Password you’ll have to use the Linux CUI to login using PW easybot
Sorry I should put a warning in here, be careful going into the Linux environment and making changes, certain changes can potentially break the operation of your robot. If you are not comfortable navigating Linux and deleting the password files yourself contact your supplier/vendor/integrator or create a ticket with UR so they can resolve the issue for you.
Hope this helps and best of luck!
