What is the difference between "Full name" and "User name (pseudo)"?
Since March 18, 2026, and the implementation of the new authentication system on FUN‑MOOC, the content of this procedure is being updated. An updated version of the article will be available soon.
When creating your account, you must be careful when entering your full name and your user name, which are two different elements and cannot take the same form for reasons of input criteria.
Note that it is your user name that will be used as your identifier for the forum or the assignments you submit.
Your full name
Your full name consists of your first and last names. This is the name that will appear on your attestation of successful completion or your paying certificate.
It can be changed as long as no attestation or certificate has been generated in your account settings (https://lms.fun-mooc.fr/account/settingshttps://www.fun-mooc.fr/account/settings). If a certificate has been issued, any changes will only apply to future issues.
Username or pseudonym
The pseudonym or username on FUN can NOT be changed by the end user in their profile; the field is fixed once registration has been finalised.
The username is a unique identifier on the platform. It's a short name that doesn't have to reflect your real identity because it's visible to other participants. You need to be imaginative to find a username that hasn't already been used. Note that it must not contain any spaces and that only letters, numbers and hyphens are permitted.
If you have to submit an assignment on an external platform, it is this pseudonym that must be entered and not your full name.
For information on the other fields, please see this article on creating an account.
