You have just received your credentials from the Institut Catholique de Paris, and the Sesam ICP portal seems opaque to you. The website address, the format of your login, the button to click: every detail matters to avoid wasting time between classes. This guide details the technical points that really cause issues during the first login and on a daily basis.
Propagation Delay After Activating Your Sesam ICP Account
The homepage of the portal does not mention this point, yet it generates a lot of confusion. After creating or resetting your password, a delay of a few hours is normal before full access to all digital services.

You may manage to log in at sesamicp.fr but find that Moodle, your email, or the Eduroam Wi-Fi remain inaccessible. This delay is explained by the propagation of your rights across several distinct servers.
What to do during this delay? Do not attempt to reset your password a second time. Each new request restarts the propagation process. Wait, then try again after a few hours. If the problem persists beyond a day, it is likely another issue, detailed below.

To access the Sesam ICP login smoothly, keep this delay in mind during each enrollment or password change.
Sesam ICP Identifier Format Based on Your Status
You may have noticed that the error message never specifies whether it is the login or the password that is causing the problem? In most cases, the error comes from the format of the identifier, not the password.
The ICP portal assigns a different address format based on your profile. Here are the four scenarios:
- Students: the format is [email protected] (example: [email protected]). Note that some internal documents still mention the old suffix @icp.fr.
- Integrated Teachers: the format is [email protected], with the first letter of the first name followed by a dot and then the last name.
- Adjunct or External Teachers: the format changes to [email protected], a suffix that can easily be confused with the previous one.
- Other Users (administrative staff, occasional speakers): the format is [email protected].
Copy your exact identifier from the activation email rather than retyping it from memory. An unintentional uppercase letter or a space at the end of the field is enough to block authentication.
SSO Login or Classic Login: Choosing the Right Door
The Sesam ICP login page offers two distinct buttons. The first, labeled “ICP Login (SSO)”, uses single sign-on authentication. The second is a classic form with identifier and password.
What SSO Changes on a Daily Basis
With SSO, you enter your password only once per session. As long as your browser retains the authentication token, each related service (Moodle, email, schedule) opens without asking for your credentials again.
The classic login, on the other hand, requires entry each time a service is opened. It remains useful in a specific case: when you are using a shared computer (library, computer room) and do not wish to leave a session open.
Browser and Cookies: Two Technical Prerequisites
SSO relies on session cookies. If your browser is configured to delete them upon closing, SSO will ask for your credentials again at each visit. Check this setting in the privacy settings of Chrome, Firefox, or Safari.
An overly aggressive ad blocker can also interfere. If the login page keeps looping without success, temporarily disable your blocking extension on the domain sesamicp.fr.
Resolving a Sesam ICP Login Block Without Contacting Support
Before contacting support, three quick checks eliminate the vast majority of blocks:
- Clear the browser cache and cookies, then try again. Old session tokens expire and cause silent errors.
- Test another browser or a private browsing window. If the login works, the problem lies with an extension or a local setting.
- Ensure that the URL is www.sesamicp.fr and not a variant (rec.sesamicp.fr is a test environment, not the production portal).
If none of these steps resolve the issue, the official support remains.
Contact ICP-Hub for a Persistent Problem
ICP has set up a single point of contact, the ICP-Hub, which also handles access difficulties to digital services. You can reach them by phone at 0 805 805 002, by email at [email protected], or in person at building L, room L002, 74 rue de Vaugirard in the 6th arrondissement of Paris.
When you contact them, specify your full identifier (with the suffix), the browser used, and the exact error message displayed. These three pieces of information speed up diagnosis and avoid back-and-forth communication.
Mobile Access to the Sesam ICP Portal
The portal works from a mobile browser without a dedicated app. Type sesamicp.fr in Safari or Chrome on your phone, then use the SSO button just like on a computer.
Add the page as a shortcut to your home screen for one-tap access. On iOS, open the share menu and then “Add to Home Screen.” On Android, tap the three dots and then “Add to Home Screen.”
The Eduroam Wi-Fi on campus uses the same credentials as Sesam ICP. If you cannot connect to the wireless network after your registration, the propagation delay mentioned above is the most common cause.
Your connection to Sesam ICP relies on the correct identifier format based on your status, the choice of the appropriate SSO mode for your context, and the patience required after each password change. Keep the ICP-Hub address handy for the rare cases where these checks are not sufficient.
