Are SSH keys tied to user?

The public key is placed into the home directory of the user on the server who used ssh-keygen and ssh-copy-id to generate it and put it there. If you use ssh to connect to the machine with no username, it will attempt to connect with the username of whoever is logged in.

What is public and private key?

In Public key, two keys are used one key is used for encryption and another key is used for decryption. One key (public key) is used for encrypt the plain text to convert it into cipher text and another key (private key) is used by receiver to decrypt the cipher text to read the message.

How do SSH keys work?

An SSH key relies upon the use of two related keys, a public key and a private key, that together create a key pair that is used as the secure access credential. The private key is secret, known only to the user, and should be encrypted and stored safely.

What is my private key Linux?
