Can I link enterprise and accounts?

I have a GitLab account on an enterprise instance. I now need to do work on a public repo at Is there a way I can use my enterprise account as a account? Or is there some way to link the two?

I have separate accounts on our each of own instances and on (and at least one more self-hosted GitLab instance) and haven’t seen any option to link them.

As you can conceivably have accounts on multiple instances beside, and as those instances can be configured however the local admin wants, there’s no way can support using those accounts.
