Forgot your password?

You have requested access to a secure site of the Université Claude Bernard Lyon 1 which requires identification. By connecting via this portal, you undertake to respect the charter governing the use of the information system.

For security reasons, please log out and exit your web browser when you are done accessing services that require authentication!

The web resource that you requested requires you to activate your account. In order to do this you will need to authenticate your Lyon 1 account using the SESAME website. You can also use the SESAME website to change your password.

If you are a student:
your identifier is your student number, the first digit of which is replaced by P (if the 1st digit is 1) or X (if the 1st digit is 9) or W (if the 1st digit is 8).

If you are a staff member:
your identifier is in the form 'firstname.lastname' without the accent.

Your password is the one you must have defined in the SESAME application.
