Question Best method to use Git auto deploy

[Miguel Nunes]

I have a Plesk installation with several subscriptions and each subscription has one SSH key, obviously. I am starting to configure each website to automatically deploy when a certain branch is pushed into GitLab (private repositories). Thing is, I need to add a different SSH key for each subscription into a Plesk GitLab user I created.

Is there another method to do this? Maybe with a single SSH key, or using HTTP auth (less secure?).
