Cannot get ssh-add -A to work... keeps saying "No identities found in keychain" about ssh-keys-in-macos-sierra-keychain HOT 12 CLOSED

I'm experiencing an issue that ssh-add -K silently doesn't add non passphrase protected keys to the keychain (though it works fine for password protected keys). I'm on High Sierra.

A workaround for this is to add a passphrase to the key temporarily:

ssh-keygen -p -f ~/.ssh/id_rsa
# when prompted, input a temporary password

Next, add the key to the agent (and Keychain) using ssh-add -K. Then, remove the passphrase from the key:

ssh-keygen -p -f ~/.ssh/id_rsa
# when prompted for a new passphrase, leave it blank

The passphrase-less key can henceforth be added to the agent using ssh-add -A.

and tried to re-add it using ssh-add -K, but now no matter what I do, I cannot get it back into the OSX Keychain app...

@jbarker4682 Is your key passphrase protected? I'm experiencing an issue that ssh-add -K silently doesn't add non passphrase protected keys to the keychain (though it works fine for password protected keys). I'm on High Sierra.

If you simplify your ~/.ssh/config to just:

Host *
  IdentityFile ~/.ssh/id_rsa
  AddKeysToAgent yes

and reboot, then ssh add -K ~/.ssh/id_rsa... do you see your entry in the macos login keychain?

Then you should ensure an ssh-add -A comes back clean (I prefer the ssh-add -A plist approach due to ssh-agent forwarding not respecting UseKeyChain)

Do not struggle with this. ssh-add in MacOS only store passphrase in keychain. not the key itself.

Following up on @wpc009's comment — the "No identity found in the keychain" message means that those passphrases aren't in the keychain (yet). To get them in there, you need to first use ssh-add -K (or ssh-add --apple-use-keychain). After that ssh-add -A (or ssh-add --apple-load-keychain) should work.

Yes... after adding the key via ssh-add -K, I used ssh -T to connect to github... But this still does not fix my problem...

As an additional step, I removed the key from the mac OSX Keychain app and tried to re-add it using ssh-add -K, but now no matter what I do, I cannot get it back into the OSX Keychain app...

The only thing it seems to do is add the key to the current ssh instance, which as soon as I reboot, is cleared so I have to re-add again... None of the listed "fixes" seem to work for me...

Should I raise a support ticket with Apple?

So, after many months of no resolution, after upgrading to Mac OS High Sierra 10.13.6, I found out that my KeyChain had become corrupted... Per directions I found here I deleted and recreated it... After this, I was able to add my SSH key's automatically by adding ssh-add -A to a startup plist...

Your suggestion didn't work out to me. I have macos Monterey 12.1 and 4 ssh keys (respectively added to config file).

The key is already in my keychain... that's why I don't understand why ssh-add -A returns the error message about no identities... It's there and I can see it...

Have you tried to use your SSH key? After running ssh-add -l till the time I actually use the key my ssh agent also got no identites. After using the key agent lists the keys I have used.

In my case there was a clash between my github email and the enterprise email.
I solved creating the ssh key using the enterprise email
ssh-keygen -t rsa -b 4096 -C "[email protected]"
