SSH Login Without Password

Show how to login via SSH without password.

Assume that your host computer is A, the other one that needs to login via SSH is B.

First, generate keys.

Run this command in both A and B:

ssh-keygen

Then exchange public keys.

Create a file named authorized_keys in ~/.ssh in B. Open ~/.ssh/id_rsa.pub in A and copy its content to ~/.ssh/authorized_keys in B.

Create a file named authorized_keys in ~/.ssh in A. Open ~/.ssh/id_rsa.pub in B and copy its content to ~/.ssh/authorized_keys in A.

Now you can get rid of password.
