Admin password authentication failure

Just recently installed Manjaro through VirtualBox. Works fine so far, but whenever I try to change the time zone in the settings or install updates for its apps, I have to enter the admin password. I give the exact password that I typed it out during installation, and it comes back with authentication failure. I’m definitely sure that I’m using the same keyboard settings, and there were pretty much just numbers/symbols in the password. Any way to bypass this?
