How To Connect To An OCI Linux Instance Using SSH Password Authentication Instead Of SSH Keys

edited Jun 30, 2022 1:57PM in Linux

How to use password based authentication instead of ssh keys to log into a Linux OCI or OCI-C instance.


SSH key-pair authentication is more secure than password-based authentication, and it is the recommended configuration for a user logging in to an instance via ssh. It is assumed that the user account you want to change to using password-based authentication already exists and has previously been configured to use an SSH key-pair to log in to the instance.


Enabling password based authentication for a specific user does not prevent them from using a correctly configured SSH key-pair to log in to an instance via ssh, it just adds an additional method of authentication that the user can use when logging in via ssh to the instance.

Howdy, Stranger!
