Question

SSH

I made ssh-keygen without changing the name, copied the data from the public to the github account - it works.
I did ssh-keygen with a name change, ... - it does not work
, I did the same steps, maybe I missed something?

ssh-keygen generates a NEW key. You can have multiple keys and add them all to your account
