How to: Reset your OS X password
In the nearly 10 years I’ve been running OS X, it hasn’t happened to me yet, but the day when I stare blankly at my Mac’s login screen is coming — it’s just a matter time. Thereupon, it’s better to be prepared for the inevitable, so read this tutorial, print it out and put it where you can find it when the time comes.
If you’ve forgotten your password, there are two ways to get into your Mac and reset it. The first can be accomplished with a retail OS X install disk or the DVD that came with your Mac.
The second method, although it does involve some command line voodoo, is actually faster and (I think easier) than using the DVD method. But, first things first.
Here’s what to do:
• Insert the DVD to the tray
• Restart and press down the letter ‘C’. It will load the installer DVD
• On the first screen, select Installer > Reset Password
• Select your account and make up a new password.
• RebootSee also: AppleDoes
The second method, as noted, requires use of the command line, but should get your in and out much faster than booting from an OS X install disk, which is always a glacial process.
Here’s what to do:
• Hold Apple+S when booting to enter single user mode
• #sh /etc/rc
• #passwd yourusername
• #rebootSee also: LifeHacker
The # sign indicates the terminal prompt and you don’t need to type that. Also, after typing each command, hit the Return key.
Of course, in line three where it says “yourusername,” you will need to your login (a.k.a. user name).
And, that as we say in the business, is that.

4. Use the built-in administrator account which you can logon without password in safe mode.It was built when you install your system and its password default as blank.Press ctrl+alt+delete twice in the welcome screen and you can see a classical logon dialog box,type administrator and press Enter.Or you can press F8 when you start/restart your computer to select start from safe mode.
