It looks like you have two accounts on our Gitlab instance:
The first - lirw1984 - was automatically deactivated by Gitlab after 90 days without connection (I can reactivate it). It had been created locally in June 2018.
The second - lirw19841 - still active, was created in novembe 2021 following a connection via the OAuth GitHub.com service.
None of these accounts is associated with an identity on the Gitlab.com forge.
A shout out to people using Orekit’s gitlab via GitHub: the latter now requires double factor authentication. Since October 12th if I recall correctly.
