Generate ssh keys on machines A and B respectively, and then add the public keys of A and B to github.

For detailed process, please check the help provided by github: common SSH Problems

Of course, you can only generate the key pair on A and then copy the private key generated on A to B. The public key only needs to be uploaded once

It is best to generate two pairs of keys, which is easier to manage.

Sharing a key is neither elegant nor secure.
In fact, you can upload multiple keys. I have encountered this problem before. For specific steps, you can read the first part of my article: Problem-driven Git learning.
