> Greetings from Amazon Web Services,

> In the past, you have used the same email address and password to sign in to Amazon.com and AWS. In response to customer feedback, AWS is updating your account to make your access to Amazon.com and AWS independent. You can continue using this email address and your current password to sign in to Amazon.com. However, the next time that you sign in to AWS, you will be prompted to create a new password and will have the option to register a new multi-factor authentication (MFA) device.

I was definitely surprised when I first signed up to AWS (having an Amazon.com account for a long time beforehand) that it used the same credentials. I'm glad they are finally separating them, and frankly surprised it took this long!
