After I changed my user from administrator to standard user to setup Parental Controls on my own account, which was the first account I created on my fresh installation, I could not login with the same password I used before (To setup Parental Controls I created another account called Admin and gave it admin rights, then through that user, I changed my own user to standard, which I reverted and deleted that Admin account after this problem). I'm pretty sure it has nothing to do with the keyboard layout because I can login through the login screen of Ctrl+Alt+F1. And the reaction of the password bar is different than when the password typed is wrong. Because if it is wrong it shakes after a second or two delay, but when I type my correct password, it shakes immediately. So far I tried deleting and checking the ownership of ~/.Xauthority, in separate occasions, but it did not work.
Also I can log in automatically eventhough the toggle of "log in automatically" in user accounts settings is turned off, and when I try to turn it on and reboot, it turns off again, yet I can still log in automatically.
I'm on elementary OS 5.1 Hera. I looked around the web but couldn't find any solutions, hope you can help me.
