Providing a sound user experience with security is one of the most critical parts of app success. But as a developer, no one likes to implement a “forgot password” feature for every other app! Implementing token generation and maintaining a bulky authentication flow can haunt your time to market for the next big thing.
Without a doubt, authentication is one of the most critical aspects of many applications we develop. But in today’s era, where competition is high, businesses cannot spend too much time developing basic features to get their core services available.
Serverless authentication helps developers focus on solving real business problems rather than engaging in some boring auth flows. Today, there are many solutions available to implement authentication with utmost ease in your applications. Here, we have analyzed the top serverless auth providers to help you make an informed decision for your next unicorn idea.
