RSA key, github keeps asking for my password
Solution 1:
You've put a passphrase on your local key. You need to either remove the passphrase (not really recommended unless it's a single-use keypair) or run a user-agent that will essentially 'remember' that you've decrypted the key once and not ask you to do so again. ssh-agent is the one that comes with openssh. The usual procedure is to set up ssh-agent to autostart at login.
Github has a decent, if a bit minimal, tutorial on it.
