Create new SSH keys
Follow the GitHub guide:
Migrate SSH keys to a new computer
This is a little tricky, but easier than changing SSH key everywhere you authenticate with SSH.
Copy these files from your old to new computer:
~/.ssh/config ~/.ssh/id_rsa ~/.ssh/id_rsa.pub
Note: I skipped copying the
~/.ssh/known_hosts file. Stuff builds up. We’ll start fresh later.
Add your SSH key to the
# Start the SSH agent eval "$(ssh-agent -s)" # Add the key ssh-add -K ~/.ssh/id_rsa
You’ll be prompted to enter the passphrase (mine is saved in 1Password).
~/.ssh/known_hosts file needs to be seeded with connections next.
Test the GitHub connection, and verify the response (reference):
ssh -T firstname.lastname@example.org
Test the Bitbucket connection, and verify the response (reference):
ssh -T email@example.com
Try fetching from your repos, and it should work.
Apple stopped saving SSH passphrases in its keychain in macOS 10.12.2, which is a pain in the ass because Git prompts for your passphrase after every command.
Long term fix
Create/edit this file to fix it:
Host * UseKeychain yes AddKeysToAgent yes IdentityFile ~/.ssh/id_rsa
Host entries are matched first ➔ last, so this may need to be repeated in each additional host entry.
Short term fix
Needs to be repeated after every restart.
ssh-add -K ~/.ssh/id_rsa
You could add this to your bash profile so every terminal session starts, but people say it’s slow.
