Publii does not store password as a plain text in the site settings. It is due security reasons. The value in the password field is used to restore password from the OS built-in password manager.
Please check server settings and check if password in the settings is ok (you can show password in the Publii UI). If you will get the same value as in the site settings file – then it must be a bug (in some Publii prerelease version we had a problem with password overrides). Then please put your correct password and save server settings again.
The same problem can occur if you have migrated website files from other computer – you have to set a password again.
