Password changed by someone?

Hello. I use CIS. I had problems. The password was changed several times in the program. I did not change it myself. But I could not enter the settings. There was an inscription - “credentials are not correct.” Twice I reinstalled the operating system. It helped. Today again, the entrance to the program settings has become impossible. Today I decided to find out what the problem is. Now the hash is the same as in the photo.And password


Why can not I go to the settings?
