I can SSH in fine with my .pem file, to be automatically logged in as ec2-user.
I can create a new user and password fine, and login with
su - testUser.
How do I log back into ec2-user without exiting the SSH session and re-connecting with the .pem file?
su - and
su - ec2-user, both of which prompt for passwords.
Entering no password gives su: Authentication failure.
As far as I'm aware, there is no default password.
Or is it simply intended for one to set a password for ec2-user?
