How to push to .git repository with an appropriate .ssh key?

Question

I have two ssh keys on my laptop: work.pub for work (and it is attached to my GitHub work account) and personal.pub (for personal usage and personal GitHub account). Also I am using macOS 11.0.1.

I have following .ssh/config:

Host *
   UseKeychain yes
   AddKeysToAgent yes
   IdentityFile ~/.ssh/personal
   IdentityFile ~/.ssh/work

I have added both ssh keys to Keychain with:

ssh-add -K ~/.ssh/work
ssh-add -K ~/.ssh/personal

Still, when I tried to push to personal repo on GH I get error than my_work_github_username does not allowed to push (here I expected that my personal ssh key would take precedence)

After it failed I deleted all identities from Keychain and tried to push one more time: ssh-add -D It pushed to personal .git, but with work identity (git commit showed my work avatar and nickname, but I was expecting it to show my personal pic and nickname)

What am doing wrong? How to be able to use multiple keys on one system?

Thanks!

Starting with git 2.10, you can set a new configuration variable core.sshCommand. This specifies what value for GIT_SSH_COMMAND to use per repository.

See How to specify the private SSH-key to use when executing shell command on Git?

Looks good! What about server ssh auth? How should I manage ssh keys in this situation? – Nikita Shchypyplov Nov 22 '20 at 12:18
For ssh, use the `-i` option option to specify the key – Rodrigo Murillo Nov 22 '20 at 12:20
Thanks, and the last question! May I somehow specify "repositories pattern", for which I want to apply certain ssh? e.g. if git remote has git@github.com:workrep -> apply work.pub? – Nikita Shchypyplov Nov 22 '20 at 13:07
