## What is AWS Cognito? <a href="#what-is-aws-cognito" id="what-is-aws-cognito"></a>

AWS Cognito is used by some platforms for secure authentication based on browser details. Its advanced security feature (ASF) inspects the device and browser fingerprint of whoever is signing in and expects a matching token to be sent alongside the username and password. Without that token, or with one that does not match the request, the login is rejected.
