How to delete saved passwords in Eclipse

I saved my username and password for subversion repository but I wasn't able to change them.

After some research I found a way to clear all saved passwords and usernames. On Mac OS X just move the ~/.eclipse_keyring away or delete it if you know all your usernames and passwords.

Now Eclipse should show you the password prompt. Uncheck the save password check box if you need to use different users out of eclipse for one repository.
