What are some alternatives to Auth0, Firebase Authentication, and Keycloak?
Stormpath
Stormpath is an authentication and user management service that helps development teams quickly and securely build web and mobile applications and services.
Amazon Cognito
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.
Okta
Connect all your apps in days, not months, with instant access to thousands of pre-built integrations - even add apps to the network yourself. Integrations are easy to set up, constantly monitored, proactively repaired and handle authentication and provisioning.
Firebase
Firebase is a cloud service designed to power real-time, collaborative applications. Simply add the Firebase library to your application to gain access to a shared data structure; any changes you make to that data are automatically synchronized with the Firebase cloud and with other clients within milliseconds.
OAuth.io
OAuth is a protocol that aimed to provide a single secure recipe to manage authorizations. It is now used by almost every web application. However, 30+ different implementations coexist. OAuth.io fixes this massive problem by acting as a universal adapter, thanks to a robust API. With OAuth.io integrating OAuth takes minutes instead of hours or days.
