Amazon Cognito vs WSO2 Identity Server: What are the differences?
Developers describe Amazon Cognito as "Securely manage and synchronize app data for your users across their mobile devices". You can create unique identities for your users through a number of public login providers (Amazon, Facebook, and Google) and also support unauthenticated guests. You can save app data locally on users’ devices allowing your applications to work even when the devices are offline. On the other hand, WSO2 Identity Server is detailed as "Open source identity and access management". It helps you do single sign-on and identity federation backed by strong and adaptive authentication, securely expose APIs, and manage identities by connecting to heterogeneous user stores Leverage the power of open-source IAM in your enterprise to innovate fast and build secure Customer IAM (CIAM) solutions to provide an experience your users will love..
Amazon Cognito and WSO2 Identity Server belong to "User Management and Authentication" category of the tech stack.
Some of the features offered by Amazon Cognito are:
- Manage Unique Identities
- Work Offline
- Store and Sync across Devices
On the other hand, WSO2 Identity Server provides the following key features:
- Single Sign on (SSO)
- Identity Federation
- Strong and Adaptive Authentication
I started our team on Amazon Cognito because I was a Solutions Architect at AWS and found it really easy to follow the tutorials and get a basic app up and running with it.
When our team started working with it, they very quickly became frustrated because of the poor documentation. After 4 days of trying to get all the basic passwordless auth working, our lead engineer made the decision to abandon it and try Auth0... and managed to get everything implemented in 4 hours.
The consensus was that Cognito just isn't mature enough or well-documented, and that the implementation does not cater for real world use cases the way that it should. I believe Amplify has made some of this simpler, but I would still recommend Auth0 as it's been bulletproof for us, and is a sensible price.
