You are trying to access your iProf space from your establishment in Seine-et-Marne, and the page displays an error after clicking on your old bookmark. The problem likely stems from this: the Créteil academy has switched authentication to the Externet portal, and the old direct links like bv.ac-creteil.fr/iprof now cause redirects or blocks. Let’s go through the procedure from the correct entry point.
Externet Portal Créteil: the only reliable entry point to iProf
The primary source of connection failure is the URL. Many teachers still have a direct link to iProf bookmarked that dates back to before the centralization. This link no longer works reliably.
Access must go through the Externet portal at https://externet.ac-creteil.fr. This portal serves as a single gateway to Arena, iProf, the ENT, and academic messaging. Once authenticated on Externet, navigate in Arena to the “Personnel Management” section, then click on “I-Prof career assistant.”
To fully understand each screen and anticipate common errors, a detailed guide on connecting to iProf Créteil outlines the procedure with annotated screenshots.
If you encounter a blank page or a redirect loop after clicking on your old bookmark, delete it and replace it with the Externet URL. This is the simplest and most common fix.
Academic Identifier Créteil: why the format traps newcomers
It is often believed that the academic identifier follows the same format as the professional email address. This is a common mistake, especially among new holders and contract teachers.
The academic email address is of the type [email protected]. The login identifier, however, follows a different rule: initial of the first name followed by the last name, in lowercase, without a dot. For example, for Thierry Martin, the identifier will be tmartin and not thierry.martin.
In case of homonymy within the academy, a number is automatically added at the end (tmartin1, tmartin2). You do not always receive a clear notification regarding this. If the login fails with the expected format, this is the first thing to check with the establishment’s secretariat or the DSDEN.
The NUMEN as the default password
The initial password assigned by the academy corresponds to the NUMEN, this unique identification number of the agent. If you have never changed it, this is the one to enter. The NUMEN appears on your appointment order or your installation report.
After a successful first login, immediately change this default password. A NUMEN remains an administrative identifier that several services may know.
Browser and network: technical blocks that go unnoticed
You followed the correct URL, entered the right identifier, and the page remains stuck or loops. Before contacting support, a few quick checks can eliminate technical causes on the workstation side.
- Test on another browser (up-to-date Chrome, Firefox, or Safari). The Arena portal relies on SSO redirects that do not work well with some outdated browsers or in private browsing mode on mobile.
- Clear the cache and cookies specifically related to the domain
ac-creteil.fr. An expired session cookie can block authentication without an explicit error message. - Temporarily disable ad blockers or web protection extensions. Some extensions intercept redirects between Externet and Arena, preventing access to iProf.
- Check that JavaScript and third-party cookies are enabled in the browser settings. Arena needs them for the single sign-on mechanism.
Feedback varies on this point, but several teachers report that switching from an establishment Wi-Fi network (sometimes filtered by a proxy) to a personal 4G/5G connection is enough to resolve the situation.
Lost iProf password or forgotten NUMEN: the recovery procedure
Forgetting your iProf password is not uncommon. The recovery procedure depends on the situation.
Password changed and then forgotten
If you had personalized your password, use the reset feature available on the Externet authentication page. A reset email is sent to your academic address ([email protected]). Be sure to check the spam folder if the email does not arrive within a few minutes.
NUMEN never modified and forgotten
The NUMEN cannot be recovered online. Two concrete options:
- Contact the secretariat of your establishment, which can usually find this information in your administrative file.
- Contact the DSDEN (direction of departmental services of national education) to which you belong. For the Créteil academy, this concerns the departments of Seine-et-Marne, Seine-Saint-Denis, and Val-de-Marne.
In both cases, be prepared to provide an identification document. The response time varies depending on the time of year, with transfer campaigns generating a spike in requests.
Check your career file after logging into iProf Créteil
Once logged in, the reflex to adopt is to check that the information in your administrative file is up to date. Grade, assignment, job history: any unreported error can impact a transfer scale or advancement.
The “Your CV” section in iProf allows you to add diplomas, certifications, and training attended. These elements are reviewed by managers during promotion campaigns. An incomplete file does not block access, but it can hinder career progression without you being informed.
The iProf messaging system also allows you to write directly to your academic manager to report an anomaly. This is the most direct channel, and messages sent via iProf are tracked and retained, which serves as proof in case of an administrative dispute.
Updating your iProf space once a quarter, even without an ongoing campaign, remains the best way to avoid unpleasant surprises when deadlines are tight.
