If you are a returning user, you may request a new password to access your User Portal account by entering your current account name (initially your email address) and your last name. An email will be sent to you with a link to your account where you will be asked to change your password.

Please note that your User Portal password should not be the same as the password used for the experimental data acquisition systems, for example your LCLS/SLAC Unix Computer Account.
For information about LCLS/SLAC Unix Computer Accounts please check here.
