# generate key
ssh-keygen -t rsa -b 4096 -C "<your_email@example.com>"

# ensure ssh agent is running
eval "$(ssh-agent -s)"

# add key to agent
ssh-add -K ~/.ssh/id_rsa  # macOS
ssh-add ~/.ssh/id_rsa  # linux

# print public key to terminal for copying
cat ~/.ssh/id_rsa.pub

# share key to server
ssh-copy-id -i ~/.ssh/id_rsa.pub <USER>@<IPADDR>
# or with windows powershell
cat ~\.ssh\id_rsa.pub | ssh <USER>@<IPADDR> "cat >> .ssh/authorized_keys"
