What does the "master password" do on a MacBook Air?

I was looking around on the privacy settings on my MacBook Air, and I came across an option to set a "master password". This sounded safe, so I set a difficult one that was memorable for me. I'm just curious: What does the master password do? Why would I need one? and When can I activate it?


Thanks

MacBook Air

I already understand everything mentioned in the link. What i dont get it how to activate it. So say i forgot my normal password to my account, how could i use the master to unlock it?

That password is only for a FileVault encrypted disk. Did you use FileVault, do you have Snow Leopard (10.6)


What exactly are you wanting to do?

OS X 10.6 and earlier versions


Master Password can be used to reset login/administrator password without using Installation DVD.


If the password is forgotten, try to login to your account and enter the any wrong password 3 times.


"Forgot Password?" box will appear. Click it.


Enter Master Password and the new login password to reset it.


OS X 10.7 and later versions


You can use Apple ID to reset password in the newer version of OS X.



Best.
