I have an EC2 micro instance that has been running for years. I can still SSH into it, but I've completely forgotten the email address I used to create it.
I had been moving from email to email every year to say in the free tier until amazon made the free tier permanent. As a result, the ec2 is not tied to my main email addresses, and must have been registered under one specifically made for this purpose. Unfortunately I do not remember it.
Given that I can still SSH to the instance, how can I recover the email address so I can log into Admin console and deprovision this instance so it's not running forever?
