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.
