I added the public SSH key to the authorized_keys file.
ssh localhost should log me in without asking for the password.
I did that and tried typing
ssh localhost, but it still asks me to type in the password. Is there another setting that I have to go through to make it work?
I have followed the instructions for changing permissions:
Below is the result if I do
ssh -v localhost.

Then it asks for a passphase after the above log. Why isn’t it logging me in without a password?
You need to verify the permissions of the
authorized_keys file and the folder / parent folders in which it is located.
chmod 700 ~/.ssh chmod 600 ~/.ssh/authorized_keys
For more information see this page.
You may also need to change/verify the permissions of your home directory to remove write access for the group and others.
chmod go-w ~
