The most valuable features of Amazon Cognito are the pre and post-token generation, and the different Cognito triggers. It has lots of functionality and flexibility.

I think Amazon Cognito provides less flexibility to customize at the moment.

Cognito has the possibility to render the login screen and all the customer flows related to managing the account. Still, it's useless in an international setup. They are unable to localize these screens, so we had to write our own screens and just use the Cognito API.

I would rate its scalability as five out of ten. Moving users between different pools or accounts creates new identities, which means IDs stored in our database must also be changed.

Amazon Cognito could be improved by making it easier for us to add more data to the token, allowing customization of JWT. It requires a complex program to customize the token currently, however, the UI could support this configuration better.

The setup and configuration can be complex, especially for advanced use cases.

Cognito triggers can improve by providing more direct use cases rather than giving a white paper. A white paper is not at all interesting, it has too many details. It would be a benefit to provide a smaller document that is summarized. The smaller version would bring microdata, macro data is not helpful.
