Introduction

On macOS, you can set up such that your encrypted ssh keys get automatically decrypted using the passphrase stored in the Apple Keychain, which is unlocked at login.

How to

Add your passphrase to the Keychain

Create your key as usual, then do this once:

ssh-add --apple-use-keychain ~/.ssh/id_ed25519

You must use the full path your key, a relative path will not work!

Configure ssh to use the Keychain to unlock your keys

Use this ~/.ssh/config:

Host *
   IgnoreUnknown UseKeychain
   UseKeychain yes

IgnoreUnknown is there so this config will work with non-Apple ssh implementations.
