You are trying to access the Assas ENT and the page is stuck on an authentication error. Before assuming a general outage, the problem often stems from a specific detail related to your account or browser. Understanding the logic behind each type of blockage allows you to regain access in a few minutes, without waiting for a response from support.
Discontinuation of the old Assas messaging system and redirection errors
Since the start of the 2025-2026 academic year, the old messaging system etudiants.u-paris2.fr has been permanently discontinued. This change causes a concrete problem: students who still use an old link to the webmail or a bookmark saved from the previous year encounter an error page or a redirection loop.

The reflex to adopt is simple. Delete all your old bookmarks pointing to the webmail etudiants.u-paris2.fr. Always go through the main portal ent.u-paris2.fr, then click on “log in” at the top right. Your username remains your full email address in the format [email protected], even if the associated messaging has migrated.
If you had configured an email client (Outlook, Thunderbird, your phone’s Mail app) with the old settings, those connections will also fail. You need to reconfigure the client with the new settings provided by the university. Finding a solution for the Assas ENT connection starts with this verification of the entry points used.

Incomplete administrative registration and blocked ENT account
You have received your student card but the ENT refuses your password. Have you checked that your administrative registration is actually finalized?
An outstanding payment blocks the creation of the digital account. As long as the bank or university has not validated the transaction (rejected direct debit, uncashed check, installment payment with a failed due date), the system does not generate or reactivate your ENT credentials. The interface does not tell you “incomplete payment”: it simply displays “incorrect username or password”.
To check your situation, contact the registration office of your affiliated center directly. The contact details are on your provisional enrollment certificate. If you are re-registering, the problem often occurs when transitioning from one year to the next, when the administrative file has not yet been transferred to the system.
Where to find your initial password
The password for your Assas computer account is indicated at the bottom of your enrollment certificates. Your username is on the back of your student card. If you have changed this password and then forgotten the new one, the password reset page is accessible at applisweb.u-paris2.fr/MotPasse/accueil.
If this procedure fails, send an email to [email protected] specifying your student number and full name.
Agor@ssas maintenance and false connection issues
The Agor@ssas educational platform undergoes scheduled maintenance windows that temporarily cut off access. For example, an unavailability may be scheduled on a Monday from 1 PM to 1:30 PM. During this time, the page displays an error or does not load, which resembles a personal connection issue while the service is simply on technical pause.
Before resetting your password or clearing your cache, check the Agor@ssas homepage. Maintenance is announced there with the exact date and time. If your login attempt coincides with a displayed window, wait a few minutes and try again.
Differentiating a personal outage from a server outage
- If the main ENT (ent.u-paris2.fr) is working but Agor@ssas is inaccessible, it is probably a targeted maintenance on the educational platform.
- If no Assas service is responding (ENT, Agor@ssas, Doc@ssas, video podcasts), it is a network outage on the university side. In this case, no local manipulation will resolve the issue.
- If the ENT works for a classmate but not for you, the blockage is related to your account, your browser, or your local network.
Browser and cache issues on the Assas ENT portal
The Assas ENT portal uses a centralized authentication system (CAS). A corrupted session cookie prevents login even with the correct credentials. The typical symptom: you enter your password, the page seems to reload, then returns to the login form without an error message.
Here are the steps to test in order:
- Clear your browser’s cache and cookies, then close all windows before reopening a clean session.
- Try in private browsing mode (Ctrl + Shift + N on Chrome, Ctrl + Shift + P on Firefox). If the login works in private mode, the problem indeed comes from a cookie or an extension.
- Temporarily disable your extensions, especially ad blockers and built-in VPNs, which may interfere with the CAS authentication process.
- If you are using an external VPN, disable it. Some VPNs redirect traffic to a foreign server, which may trigger a security block on the university side.
The browser recommended by the university for accessing video podcasts is Firefox. For other ENT services, Chrome and Firefox work without particular difficulty. Safari on Mac can sometimes cause issues with the security certificates of the portal.
What to do when nothing works
You have checked your registration, used the correct portal, cleared the cache, tested in private browsing, and the blockage persists. At this stage, the issue falls under the university’s IT support.
Send an email to [email protected]. Specify your student number, the email address used for login, the browser employed, and a screenshot of the error message. This information speeds up the processing of your request.
If your access is urgent (online exam, submission of work on Agor@ssas), go directly to the reception of the Assas center at 92 rue d’Assas or the Vaugirard center. The IT service can reset an account on-site with an ID. This process usually takes less time than an email exchange.
