The Amiens academy has profoundly modified its authentication infrastructure between 2025 and 2026. The AC Amiens intranet no longer functions exactly as it did the previous year: some historical URLs redirect, account activation follows a strict technical prerequisite, and the entry portal has changed. This article compares the current access points, details the activation steps, and identifies the most frequent blockages.
Portal.ac-amiens.fr: the new single entry point in 2026
Until recently, academy staff were juggling multiple URLs to access their email or business applications. The situation has simplified, but it generates confusion for those still using old bookmarks.

| Access Point | Status in 2026 | Function |
|---|---|---|
| portal.ac-amiens.fr | Active official URL | SSO, webmail, access to applications |
| intranet.ac-amiens.fr | Redirects to the portal | No longer provides direct access |
| webmail.ac-amiens.fr | Obsolete, partial redirection | No longer updated |
Portal.ac-amiens.fr has become the single entry point for email and SSO for most applications. Specifically, typing webmail.ac-amiens.fr in a browser may still redirect to the correct page, but this URL is no longer maintained. A bookmark pointing to this address risks ceasing to function without notice.
Anyone looking for access to the AC Amiens intranet must therefore update their shortcuts to portal.ac-amiens.fr to avoid looping connection errors.

Account activation via My Academic Assistant: the mandatory technical prerequisite
The main cause of blockage in 2026 is not a forgotten password. It is a account never activated via My Academic Assistant. Since the 2024-2025 updates, this step conditions everything else: without it, the agent cannot access the intranet, webmail, or Arena, even if they know their NUMEN.
Activation process
- Go to the My Academic Assistant tool (accessible from portal.ac-amiens.fr)
- Enter your NUMEN and date of birth to validate your identity
- Set a permanent password that replaces the temporary password
This process is not a mere administrative formality. It is a systematic technical prerequisite that conditions the generation of SSO authentication tokens. An agent appointed in the academy in September who does not complete this activation in the first few days finds themselves cut off from all digital services.
On the other hand, once activation is completed, the unique identifier (usually in the format firstname.lastname) and the chosen password provide access to all applications: academic email, Arena, I-Prof, Gaïa, Cyclades, Colibris, and collaborative spaces.
Authentication by OTP: what the login page actually offers
The login page of the Amiens academy displays two distinct authentication modes. The first is classic: academic identifier and password. The second relies on an OTP (one-time password), via an academic OTP or an ODA.
The OTP is not reserved for executives or management staff. Any agent with a configured OTP device can use it. This method enhances connection security, especially when accessing from a personal computer or an external network.
The distinction between the two modes has practical implications: if an agent usually uses the OTP and tries to log in with a classic password (or vice versa), the page may return an error without an explicit message. Checking which mode was configured during activation avoids this type of blockage.
Recovering identifier or password
The academy centralizes the recovery procedure at portail.ac-amiens.fr/motdepasse/pertemdp.php. This page handles both identifier loss and password reset. A single form manages both cases, simplifying the process compared to dual-procedure systems.
Services accessible after logging into the Amiens academic portal
Once authenticated, the portal displays applications according to the agent’s profile (teacher, administrative staff, management staff). The list is not the same for everyone.
- Academic email (webmail) with storage and management of professional contacts
- I-Prof for consulting the career file, transfer requests, and managing the professional CV
- Arena for accessing business applications (student management, exams, oversight)
- Gaïa for enrolling in training and tracking the individual training plan
- Colibris and collaborative spaces for teamwork and document sharing
Administrative staff also access HR management modules and tracking of administrative acts. Access rights depend on the profile linked to the NUMEN, not on a manual choice by the user.
Frequent blockages and checks to perform before contacting support
Before opening a support ticket, a few quick checks resolve the majority of connection issues.
The first is to test access in private browsing. If the connection works in private mode but not in normal mode, the problem lies with the browser’s cache or cookies. Clearing the cache and deleting cookies related to ac-amiens.fr usually suffices.
The second check concerns the URL used. An old bookmark to webmail.ac-amiens.fr may cause redirection loops. Replacing it with portal.ac-amiens.fr resolves the issue.
The third concerns the case of the password. Authentication is case-sensitive. Accidental activation of caps lock is a frequent cause of rejection, especially on laptop keyboards.
If these checks do not resolve anything, the support page accessible from the login page (section “Need help?”) directs to the academic technical support. Preparing your NUMEN, identifier, and the exact error message speeds up the processing of the request.
The transition to portal.ac-amiens.fr as the single entry point and the requirement for activation via My Academic Assistant are the two structural changes of 2026. Updating bookmarks and verifying that your account has been activated by this tool remains the first action to take for all staff of the Amiens academy.
