How to grant access?

Question

linux

Hello,
let's say there is a server where they can only connect by key.
I received a task (received public keys) to create 10 users so that they can connect as well.
How is it implemented?

Answer 1

Users are created, passwords or keys are configured, group memberships are distributed. Be specific about the difficulty.

Answer 2

adduser username
usermod -aG group (for example sudo) username
then write the public part of the key to /home/user_name/.ssh/authorized_keys

Answer 3

Customize sftpin/etc/ssh/sshd_config
