I'm logging into a server that I own with PuTTY on Windows. Is there any way that I can save the passphrase for my private key (like I can in the Keychain on my Mac)?

You can store the passphrase for your private key, for the current session, using Pageant, PuTTY's SSH agent:
.ppk
private-key file.But you cannot store the server password itsef:
A.2.8 Does PuTTY have the ability to remember my password so I don't have to type it every time?
No, it doesn't.
(snip)
In SSH, remembering your password would be possible in theory, but there doesn't seem to be much point since SSH supports public key authentication, which is more flexible and more secure. See chapter 8 in the documentation for a full discussion of public key authentication.
(See also PuTTY wishlist: remember-password)
On Windows, I have my private key passwordless but encrypted using the EFS, so it can be loaded at startup automatically but only if I log in with my password. (Previously I had it in a TrueCrypt volume, with that volume's keyfile on an USB drive. Don't ask me which is more secure, if at all.)

You cannot store the passphrase for your private key permanently using Pagent, PuTTY's SSH key agent. You will have to store it unencrypted if you wish to avoid retyping the passphrase again and agian.
I suggest protecting all your keys with one standard easy to type passphrase.
1Your link A.2.8 refers to user name/password. But you're supposedly talking about keys already, and the passphrases that go with them. I don't get it. Where is the documentation saying you can't save your key passphrase? If that is impossible, then is it possible to use a key that doesn't require a passphrase? – Buttle Butkus – 2017-04-30T19:03:39.777
