How to "SSH" into an AWS EC2 Instance without SSH key

 This gives you terminal access to your EC2 instance. You will just need your AWS CLI setup, with permission to SSM. This is not really using "SSH". So the machine doesn't need SSH port open, nor need an SSH key to login.

1. Find out your EC2 instance id from AWS Console.

  Example instance id: i-0f85466ff323216f8

2. Run the SSM command:

 aws ssm start-session --target i-0f85466ff323216f8

  This should give you a terminal to the instance.
