If you are logged into your account

From any page, click the Account dropdown in the main menu and select Change Password. Use the fields to change your password.

If you cannot sign in, use the Forgot Password link on the sign in page. Enter your email address and follow the steps. You will be given a temporary password and an email will come your way with instructions on how to sign in. If you don't have a valid email address, and you are using a @myppm.org address to sign in, your group leader will need to reset your password for you.

Once you are signed in with your temporary password, you will be asked to choose a permanent password.
