Can anyone help me. Yesterday I installed the first os update since I installed mountain lion on my 2010 MacBook Pro. All went as normal for a bit until a message came up saying it was unable to complete the update and was going to restart. Fair enough I thought until it returned me to my login screen. My password no longer worked. I tried a few recent passwords in case it had stepped back in time. No joy. So I tried to use my master password to reset the password. Again, It had forgotton that too. So I am now locked out. Anyone got any ideas? My next move is to put it into target drive mode with a FireWire to thunderbolt cable and pull off my aperture library and a few other things and then clean install post disk format but I am open to easier alternatives if anyone has any suggestions. Thanks.
Got a tip for us?

have you tried booting into single user mode?
there's also recovery system (either R or command+R on boot) - that's like putting a system disk in, maybe you can reset password that way?

Today I did a fresh install of Mountain Lion and during the installation I set a user password. However, when I proceeded to use my MBP, it didn't ask me for password.
I tried restarting my Mac and it was as though I hadn't set up a password. Then I went to Users & Groups and re-set my password. To no avail.
Does anyone have any idea what's going on??? For some reason I cannot set up a password on my MBP! I've also updated to the latest version of 10.8.2., btw.

Wow, thanks! It was indeed Automatic login, you saved the day! 
What I don't understand is how did I set it up in the first place? I just did a default installation of Mountain Lion and set up a password (and I've done several fresh installs in the same fashion on different machines lately, yet on none of them had this automatic login "problem").
