I have just set up SSH key pairs for logging into my Pi remotely from my windows box with Putty in my home network.

It does not prompt for a password (as I have set that to "no" in sshd_config).

But when I login with putty, it prompts me for the passphrase for the RSA key everytime.

How do turn off the passphrase prompt? I just want to login without entering any passphrase, and have it based on private/public key creds alone.

I seem to have a found a solution, but I'm not sure if there is a better way.

I have Pageant (Putty authentication agent) running and I ensured my private key has been added.

Putty now authenticates automatically.

  • Great solution - another way is to save the private key without password protection, but that is not very secure at all.. :-) – Jervelund Dec 28 '13 at 9:56

    +1 I'm not a Putty or Windows user, but for posterity, the equivalent of Pageant if you are using ssh from, e.g., a linux terminal or X session, is ssh-agent -- you register a key with it and enter the password once, thereafter you don't need to enter a password every time you use SSH. – goldilocks Dec 28 '13 at 14:03
