Q: Forgot my login password. How do I get in to my mac

iOS is only for mobile devices. You are running a version of OS X.

If it's running Mac OS X 10.7 or newer, restart with the Command and R keys held down, open the Terminal, and use the resetpassword command:

For Lion or later:  http://support.apple.com/kb/HT6022

For Mavericks users:

you can boot into the terminal (command + s at boot) and type this in order:

mount -uw /

rm /var/db/.AppleSetupDone

it will take you to the set up your mac screen again in which you create another admin account. hopefully that's a start
