Password seems to be fine when logging in but in settings the password seems different and i dont know it

when i installed manjaro gnome i remember setting the password to be same for admin as well. but now i can log in fine but i couldnt change anything. is there any way to figure out since i can log in fine. /sorry for my bad english and its not my first language

I’m not sure if it’s the exact same problem you’ve run into, but maybe this solution can fix it:

thank you so much for that. but it seems like my root password is same as that i think because it shows as incorrect
