The e-campus Police platform relies on a centralized authentication mechanism called CALYPSSO, managed by the Ministry of the Interior. A blockage when entering your password does not come from the training platform itself, but from the ministry’s single sign-on authentication infrastructure, hosted on the domain auth.sso.police.interieur.gouv.fr.
CALYPSSO and e-campus Police: why the password does not depend on the platform
E-campus Police neither creates nor stores user accounts on its own. Each agent logs in through the CALYPSSO portal, which centralizes authentication for all internal digital services of the Ministry of the Interior. The password used on e-campus is therefore the same as that of other ministerial tools.
This architecture has a direct consequence: changing your password on an internal service changes it everywhere, including for e-campus. An agent who changes their credentials via another ministerial portal without remembering them when logging into e-campus will face an access denial, even though the training platform is functioning normally.
If you encounter difficulties related to logging into e-campus Police, the first reflex is to check if the problem occurs on another ministry service using CALYPSSO. If so, the issue does not come from e-campus but from the ministerial account itself.
Frequent blockages that are not password issues
Several situations resemble a password denial but stem from another cause. Confusing them wastes time, as the reset procedure will not resolve anything.
Blank page or redirect loop
A blank page after entering credentials, or a redirect that continually brings you back to the login page, usually indicates a temporary interruption of the CALYPSSO service. The password is correct, but the authentication server is not responding. Waiting a few minutes or checking with the CNAU (National User Support Center) can confirm the incident.
“Unknown identifier” message
This message appears when the agent’s profile is not registered in the ministry’s directory. Even with a valid password, the login fails because the account does not yet exist on the CALYPSSO side. This situation particularly affects agents who have recently been assigned or transferred and whose HR file has not yet been validated.
Inconsistency after a password change
When an agent changes their password on a ministerial service (professional email, intranet), the new password replaces the old one on all portals linked to CALYPSSO. If the agent then tries to log into e-campus with the old password, the connection is denied without an explicit message about the real cause.
Resetting the e-campus password via CALYPSSO
The reset procedure does not go through e-campus but directly through the CALYPSSO portal. The steps are as follows:
- Access the e-campus Police login page and click on the button redirecting to CALYPSSO (auth.sso.police.interieur.gouv.fr).
- Use the password reset link provided on this page. An email is sent to the professional address ending in @interieur.gouv.fr associated with the account.
- Follow the link received by email to set a new password, which will be immediately active on e-campus and all other ministerial services.
- If no email arrives after several minutes, check that the email address registered in the ministry’s directory is up to date by contacting the CNAU.
A point often overlooked: the reset link expires quickly. If the email remains unopened for too long, you will need to restart the procedure from the beginning.
Contacting the CNAU in case of persistent blockage
The CNAU is the only competent contact for CALYPSSO authentication issues. The official e-campus Police login page explicitly mentions it for any connection-related incident.
Before contacting the CNAU, gather the following information:
- Your login identifier (usually based on the format first.last).
- The exact error message displayed during the login attempt.
- The browser used and its version, as some redirect issues are related to caches or outdated versions.
Specify whether the blockage concerns only e-campus or all ministerial services. This information allows the CNAU to distinguish between an account problem and a technical incident on the training platform.
Precautions to avoid recurring blockages on e-campus Police
The majority of repeated blockages stem from the management of browser cache and cookies. After a password change, the old authentication tokens stored locally conflict with the new CALYPSSO credentials. Clearing the browser cache after each password change eliminates this risk.
The choice of browser also matters. Ministry workstations generally have a preconfigured browser for internal services. Using an alternative, non-configured browser can cause certificate errors or redirect loops unrelated to the password.
Finally, the synchronization between the HR file and the ministry’s directory remains the most frequent blind spot. An agent whose assignment has just changed may find themselves with a temporarily disabled account while the systems update. Only the CNAU can manually force this synchronization in case of an abnormal delay.
