Usage / Intended Users

This service allows external users who do not have a regular CERN account to get access to certain CERN applications that are open to external users. The CERN Lightweight Account consists in your existing email address and a password.

CERN Lightweight Accounts only provide limited access to certain applications. For a full CERN intranet access, you'll need a regular CERN Account, linked to a valid CERN Affiliation. Please contact your Experiment's secretariat or the CERN User Office.

If you own a regular CERN account, you cannot create a lightweight account with the same e-mail address. If you have left CERN and your affiliation has expired, a CERN Lightweight Account will automatically be created for you, using the external Email address you provided before departure.

LightWeight Account Registration Process

You can create and activate your credentials following this process:

1. Complete the online registration form

You must provide a valid e-mail address: it will become your login to access CERN applications, and we may use it to contact you in future.

2. Validate your account

Once you have submitted the registration form, you will receive an e-mail with a randomly generated link to validate your account. This step allows us to verify that you really own this e-mail address.

If you have not received the e-mail or if the validation link has expired, use the Forgot your password ? link in the Operations menu.

3. Set your password

By clicking on the validation link, you will be offered to choose your password. This will complete the registration of your account.
