Change password in Adguard Integration

I have Adguard Home installed in a virtual machine and tested the integration of Home Assistant. Now I changed the password for the Adguard Home instance and the integration can’t connect. But I did not found a way to change the stored password. I can’t be true to deinstall and make a reinstallation, or?

Edit from 2022-12-03: Ok, one month later and not one answer from anyone? Or the home assistant team? Really? Also the “Repair” function has “no function” but the Add-On is not working and no way to reset the login data for the Adguard Home instance.
