for this you have to generate public keys and then place them to the remote machine.
In this way you would not need to typr password.

type command ssh-keygen
then just press enter dont give passphrase value
you can see you keys at

~/.ssh/id_rsa.pub

then copy the public keys and paste at remote machine
~/.ssh/authorized_keys

then next time when you will ssh the system it will no ask for pasword and same case for scp

It is a good idea to lock your private key (it is only used on the client side) with a passphrase.

You can use ssh-agent to enable entering the key once when you start a session. After that it is unlocked.

eval $(ssh-keygen)
ssh-add
