github somehow used my non ssh connected global account in a repo where my ssh github account was a collaborator

[RyuZinOh]

I have a global GitHub connection on my local machine. I recently added an SSH connection for a different GitHub account and used it to SSH-clone a repository onto my local machine.

However, when I pushed my changes, I forgot to update my local username to match my SSH account, meaning GitHub recognized my global (old) account instead of the SSH-connected one.

As a result:

GitHub used my global account to push changes, even though it wasn’t a collaborator on that repository.
My global account was somehow added to the collaboration menu of the repository.
OLD id didn’t reflected that repository’s in Code, Planning, and Automation section so i couldn't opt myself out from that. [ but ssh account shows that repo on that section]
What kind of issue is this?
Now, I want to remove my global account from the repository collaboration, but since it was masked as my SSH account during the push, the repository doesn't appear under Code, Planning, and Automation, preventing me from opting out.

You're dealing with a Git + GitHub identity conflict caused by mixing global Git configuration (user/email) and SSH keys from two different GitHub accounts. This situation has led to unexpected behavior, including:

Your global GitHub account being added as a collaborator (or contributor) to a repo it wasn’t originally tied to.

You’re unable to remove yourself from the repo’s “Code,” “Planning,” or “Automation” sections, because GitHub’s UI reflects access based on the repo being listed under a different (SSH-authenticated) account.

GitHub accepted your push because the SSH key matched a user who had push access, but Git used the global user.email/name, confusing attribution.

Is it fixable issue? Or, one can just ask the repo owner to manually remove the contributors somehow? I doubt even the owner will be able to remove that, but if he can remove the collaborator under my ssh connected account for the repo, would the global masked account who somehow got into the collaborator/contributor section would be removed?
As Github adds users into the contributor section based on the commit he/she made, or the owner would have to remove my commit that caused that issue

Fixing the Problem
✅ A. If You Were Added as a Collaborator (with access)
Yes, the owner can remove you:

Go to Repo Settings → Collaborators and Teams

Find your global (Account A) username

Click Remove

👉 This completely removes your access.

⚠️ B. If You’re Listed as a Contributor (because of commits)
This cannot be removed manually. GitHub shows contributors based on email in commits, and only rewriting Git history (or force-pushing rewritten commits) removes a contributor from that list.

➤ How to Remove Yourself as Contributor:
Repo owner must:

Rewrite commit history with correct author info (using git filter-branch or git rebase)
Force-push updated history to GitHub
Optionally, delete the original commit hashes from PRs and branches

This will:

Remove the wrong contributor from the list
Replace it with the correct one (SSH account)

⚠️ Warning: This affects all users with a shared history (force-push risk)
