The best thing I like about this is it's ease of use, especially with its integration into Microsoft Azure AD which makes authentication easier than most other providers out there (at least for my environment). Also they have some free trial as well so you can try first before making any big decisions or committing to long term contracts! Not much but nothing really stands outs at moment - just keep doing your research until everything aligns perfectly in terms of features/cost etc., otherwise things may get messy sooner rather then later when requirements change suddenly due too lack off experience / knowledge base from previous vendor who will not be around anymore once project has been delivered :) Authentication between AWS Lambda functions using API Gateway & Cognito pooling credentials across multiple projects without having separate set up per each one.
