How to disable passphrase input?

Question

linux

Hello, I have a password on my private key. Removing it is not good, it is needed. Maybe there is an option to add it to the config somewhere so that it reads it from there, and does not constantly ask me for it.
I'm on Linux myself. I always carry keys from OS to OS with me.
kde neon distribution

Answer 1

ssh-agent will help you. Enter the key once (at the beginning of the session) and that's it, then the key will be used without a password.

Answer 2

on the computer from which you want to log in without a passphrase, make a key without a passphrase and add it to the target system's authorized_case.
on other computers use the passphrase key.
