how to configure Password less authentication With Git Client and git server?

Question

After Running ssh-keygen in git bash when I am executing

$ scp id_rsa.pub [email protected]:.ssh/authorized_keys

I am getting

The authenticity of host '192.168.12.232 (192.168.12.232)' can't be established.

ECDSA key fingerprint is SHA256:v9aX9gU44tKMXefUA1V2bgPVzP1PoICupP+cpU3sNB4.

Are you sure you want to continue connecting (yes/no)? yes

Warning: Permanently added '192.168.12.232' (ECDSA) to the list of known hosts.

[email protected]'s password:

id_rsa.pub                                                  100%  403     3.2KB/s   00:00

After this when I an trying to verify weather passwordless authentication is successful or not using

$ ssh [email protected] ls

I am getting this

[email protected]'s password:

It should not ask for password I guess in this step.

What am I doing wrong can anyone help?

Run ssh command with `-vvv` to check debug output. – iBug May 10 '21 at 10:46 — iBug, May 10 '21 at 10:46
Hint: next time use `ssh-copy-id` instead of `scp`. – phd May 10 '21 at 13:45 — phd, May 10 '21 at 13:45

You need to check the rights associated to the created ~/.ssh/authorized_keys file.
As seen here or here, it should be 600 (rw-------), and an scp might create the file with rights too open for SSH daemon to operate on.

That is why, as commented, an ssh-copy-id is preferable.

Use this command after executing $ scp id_rsa.pub [email protected]:.ssh/authorized_keys

“ ssh {username}@{host:port} “chmod 700 .ssh ; chmod 640 .ssh/authorized_keys” ”

and after successful execution run you command which is asking for password.
