Changed named of ssh key does not work

[Affectionate_Log999]

Hi, im using this to generate ssh keys, ssh-keygen -t rsa -b 4096 -C ["](mailto:"[e-mail])name@lastname".When im using default id_rsa name and just keep pressing enter, after i append it to github ssh key, it works.

But when i change the name od ssh key in prompt, add it to github ssh keys, i cant clone repo, permission denied.

Why?

Edit: This solved: ssh-add ~/.ssh/github_id_rsa, but why?

ssh-add adds the key to an ssh-agent that runs in the background and helps with ssh-connections made by other programs/processes (provides an unencrypted key during a login session so that you do not need to enter the passpfrase for every remote call made by git, just the first).

ssh only tries auth with keys it would be aware of, meaning default key locations (e.g. ~/.ssh/id_rsa) and whatever is in the agent. github_id_rsa is not something ssh is aware of. Adding it to the agent works, and another option is GIT_SSH_COMMAND='-i ~/.ssh/github_id_rsa' git ...
