Set Up SSH Keys on Amazon Linux 2

Step 1. Generate new 4096 bits SSH key pair.

ssh-keygen -t rsa -b 4096 -C "[email protected]"


Enter file in which to save the key (/home/username/.ssh/id_rsa):

To accept the default file location press Enter.

Step 2. Now, it will ask you for a passphrase.

It’s recommended to use a passphrase, but if you don’t want just press Enter.

ls ~/.ssh/id_*


/home/username/.ssh/id_rsa    /home/username/.ssh/
