So let me understand about passwords:

- We have 1 password for the repository
- we have users and password with kopia server that can’t be used for log in the ui,
- so we have to specify antoher one with --server-password= and --server-username=
- we have another password that is server\_control\_password that i don’t know for what is it

everything is so chaotic. help me to understand please

If the password of a webdav server has been changed: how can I change it in kopia for an existing repository?
