If you are the administrator of an organization's Google Apps account, you may sometimes need to reset a user's password.

1. Go to Google (google.com). (If you are signed in as another account, click the user icon/picture and choose "Sign Out" )
2. Click the blue Sign in button in the upper right corner.
3. Sign in with your admin account (e.g. admin@organizationname.com)
4. Your Admin email address/id should now appear in the upper right corner where the Sign in button was.
5. Once you are signed in, go to www.google.com/a/organizationname.com *
6. Click on the Users option on the far left.  
7. Click on the user who needs their password reset. This should bring you to a page with that user and their options.
8. From the icons in the top right, click on the padlock with the arrow. (When you hover over it, it will say "Reset Password".)
9. Give your user a new password. If you give them a temporary password, make sure you check that "Require a change of password in the next sign in" box.
10. Click the Reset Password button.
11. Tell your user their new password.

*Replace "organizationname" with your company's name.
