Password required when trying to clone, Push/Pull

URL of experiment: MoanaD/goNogoTest (pavlovia.org)

Description of the problem: I am trying to push/pull or clone an online experiment from Pavlovia to Psycho Py and back. But it does not allow me to do so, asking every time for a git@gitlab.pavlovia.org password. My login password for Pavlovia does not work. Any ideas?
Thank you!
