The password you use to log on to your email is a matter between you and the email service. Many services have a "Forgot your Password?" button at the login page that you may be able to use to have them send you a new password, and/or they may show a contact phone number on the home page for the service. Unless you wrote it down somewhere, the service provider is the only one who can give it to you.

If the password is actually anywhere "on your machine," other than where you wrote it, it will be encrypted so you can't recover it from there. (If you find it and can read it you need a different service.)
