I regularly use my Mac to
ssh into other systems on my local network.
I have a public/private key (which was created 6 years ago) so I can connect without using a password.
Recently (probably since upgrading to 10.12.4) the Mac prompts with Enter passphrase for key '/Users/user/.ssh/id_rsa':
Why has this suddenly started happening?
(I presume this has something to do with changes to
OpenSSH_7.4p1, LibreSSL 2.5.0)
Can I get
ssh to connect without asking for passphrase?
Alternatively I can use a new key pair, but can I
ssh-keygen to remove the passphrase without affecting the public key?
There seem to be a number of related questions, but no solutions which seem applicable to the Mac.
Possibly useful information:-
