Resetting or changing a password:

For Snow Leopard or earlier:  http://support.apple.com/kb/HT1274

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

This is also useful:

If it's running Mac OS X 10.6.8 or earlier, insert a Mac OS X install DVD, restart with the Option key held down, click on it, and use the Reset Password utility.

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:

If it the Keychain password that needs resetting:

AFAIK, none of those deal with reetting or deleting the master password.

If you set FileVault's master password, you can remove it by deleting the FileVaultMaster files in /Library/Keychains/. If not, then I don't have a clue.

According to David Pogue's book on Snow Leopard, if you have set up FileVault and have forgotten both the FileVault password and the Master password, then the situation is not retrievable and the data in the Home folder is lost forever. This is confirmed by Apple's Tech Note:

Kappy's post here:

https://discussions.apple.com/message/15522663#15522663

suggests a method for resetting the Master password, though I don't know whether it applies if the FileVault password has also been lost - if it does, it would mean that there was no point in the entire fandango since the password has to be non-bypassable to be of any use.

I don't use FV, so haven't tried Kappy's solution and only posted what I found with a quick websearch.
