If Some one has shared his private repository to me than whenever I tries to push on that private repository it always asks me for username and password. But I have already added my private key in ssh-keys
on my personal repository using How To Add SSH Key
Now I can manage to push on my personal repository but not on other's private repository shared to me using ssh private key. Why? Is there a way to push on private repository with out adding my private key to other user's ssh keys.
