Setup ssh key for Git (macOS, Linux)

If you don’t want to authorize yourself all the time on the server, just add an ssh key.

---

1. Generate an ssh key pair on the client

$ mkdir -m 700 ~/.ssh
$ ssh-keygen -t ed25519 -b 4096 -C {user@domain.com} -f ~/.ssh/{key-name}

---

2. Add the public key to the Git server

$ cat ~/.ssh/{key-name}.pub

Settings on the server: Bitbucket, GitHub

---

3. Add the private key to the ssh agent

Temporarily

$ eval $(ssh-agent)
$ ssh-add ~/.ssh/{key-name}

Permanently

$ touch ~/.zprofile
$ echo "ssh-add ~/.ssh/{key-name}" >> ~/.zprofile

(macOS: “.zprofile” and Linux: “.bash_profile”)
