Can I use a PGP key for SSH?

An SSH key authorizes you to log into an SSH server without a password (see this guide from Indiana University for details), and a PGP key can be used to sign a document or a git commit (i.e., prove you’re the one who made it) or decrypt messages intended only for you, among other things.

How do I enable SSH access with a GPG key for authentication?

Enable the GPG subkey

1. $ cat .gnupg/gpg-agent.conf. enable-ssh-support. Optionally, you may want to pre-specify the keys to be used for SSH so you won’t have to use ssh-add to load the keys.
2. $ gpg2 -K –with-keygrip. /home/bexelbie/.gnupg/pubring.kbx. ——————————
3. $ cat ~/.bashrc. …

How do I generate a copy of my SSH key?

How is multi factor authentication implemented in OpenSSH?

Multi-factor authentication may be implemented with key pairs by entering a passphrase when the key pair is generated (see user key generation below). During authentication the user is prompted for the passphrase, which is used along with the presence of the private key on the SSH client to authenticate the user.
