Amazon Cognito hosted UI now enables end users to register their own authenticator apps. Customers can now enable users to self-enroll in either SMS based one-time-passwords (OTP) or a time-based-one-time-password (TOTP) authenticator app. Administrators no longer have to initiate end user enrollment when using TOTP with hosted UI. With this new addition, developers using hosted UI will now have the same level of security as before, but without having to develop any custom code, enabling them to focus on improving their application. Administrators will now spend less time onboarding end users to a higher level of authentication assurance. End users of the application now also have the convenience of adding their own authenticator apps and leveraging multi-factor authentication (MFA) when accessing applications that use Cognito hosted UI. Customers can benefit from a higher level of authentication for their applications at no additional cost.
