I have created a GitLab account but I put a wrong email address. I looked at ways to recover it / cancel the sign in procedure to put the good email address but I didn’t find anything.
Could someone tell me what to do (if there is something to do…)
Cheers 
Hey @unguest, welcome to the GitLab Community Forum! 
If this is regarding an account on GitLab.com, then you’ll need to submit a support ticket so that we can handle this for you. If this is regarding an account on a self-managed instance of GitLab, please reach out to your local administrator for assistance.
Update: under GitLab’s current Support policies, account recovery is only available for paid users.
