The AWS console opens in a real account, shared with the other learners: your topic and function must carry your prefix, shown on the lab page. Keep your mailbox open: you can only verify and write to your MonPremierLab account's address. If it is with Yahoo or AOL, the lab's emails may be rejected by your provider: the guide explains why. Everything is deleted at the end. The sandbox lives for three hours.
Tip
An email sent is not an email received: look in your spam folder first. And if the function fails, read who is denied: the function's role (role-lambda) needs ses:SendEmail on your identity.
