Describe the solution you'd like
I use AWS Cognito a lot for my project. I also use spring-cloud-aws, so I think it'd be great to have Spring AWS integration with the AWS Cognito user pool.

Basic features I'd like to see:

• Cognito Autoconfiguration
• User management (create a user, remove a user, log in, log out, etc)

Additional context
I can work on it

@Forfend would that be just an auto configured Cognition client or something more? With user management what implementation do you have in mind?

[Forfend]

@maciejwalkowiak I'm thinking about implementing registration, login, logout, reset password operations + Cognito client autoconfiguration. I expect this is enough to start with. What do you think about this idea?

[maciejwalkowiak]

It sounds good on paper but I'm not sure if it's possible to provide generic enough apis for that? Maybe you can draft a quick PR with a subset of features? Then we can decide if it's worth adding to the Spring Cloud AWS or perhaps it should function as a separate project.

[Forfend]

Sure, I'll do a small PoC and provide a PR in the next few days

I will be happy to have this in my project 👍
It's missing some features in the PR to fit all my needs (Signout, adminSetUserPassword, changePassword, deleteUser etc...) but it's a good start for me IMHO
