Automatically login to specified user account

Hi,

first, i apologize for my english :slightly_smiling_face:

i have a private gitlab ce installation, to publish and update webapplications for my customers. atm i’m the only one, who have an account here. My gitlab installation is set as private, same for projects.

Now i want to use the issues pages for bugreporting, issues etc. and i want to set a link inside customers projects. But i don’t want to force my customers to login here. My plan is to set a link/button where users are logged in automatically to a definied useraccount. Is this possible?
