This shows how to add a key to a new instance. My question is how to manage/create a new ssh key to an _existing_ instance when e.g. I need to add someone access or simply in the case of having a new computer?
Thank you.

I'm trying to add new pub key for new client, but it's not working. There's any limitation? I added in new console and in the authorized_keys file.

"If you created an instance without an SSH key, you can use the serial console to boot into maintenance mode and add or reset the SSH key for the opc user or reset the password for the opc user. Alternately, you can stop the instance, attach the boot volume to a new instance, and configure SSH on the new instance."
docs.oracle.com/en-us/iaas/Content/Compute/Tasks/accessinginstance.htm
I've tested the option attaching the volume to another VM with success.

Same issue :(

Check you are using the correct key type. Permissions on the key directory on your instance. Maybe this helps... docs.oracle.com/en-us/iaas/Content/Compute/Tasks/managingkeypairs.htm
