Naturally, we all choose passwords that aren’t likely to be easily
guessed by unauthorized users, sometimes we forget ourselves. It’s
always a good thing to keep your passwords written in a safe place,
like your personal address book. But if you forgot to do that and now
can’t recall what your password is on a particular web site or user’s
group, you might be able to find it by using the OS X Keychain Access utility,
which can be found inside the Utilities folder in your Applications
folder. A search field in the upper right corner lets you type in the
name of the site you’re looking for. Double-click on the result and
an info dialog box appears. To see if your password is stored there, click on the “Show
Password” box.
