Usernames for Amazon Linux (AWS) and Ubuntu AMI

For Amazon Linux, the username is “ec2-user”, for ubuntu it is simply “ubuntu”.

To connect to them you need the key file that was generated when the instance was created, and the public DNS address.  Use a command like:

ssh -i myinstance.pem ec2-user@

Note: Make sure you have opened up ssh (port 22) access to your instance from your IP address.
