12 User Authentication Platforms [Auth0, Firebase Alternatives]

User Authentication is the necessity of any online business. Let’s check some of the top tools and Firebase alternatives.

User authentication is a powerful way to provide rightful access to your digital properties like your website or application. And it obviously adds to the security and a customized user experience.

When implementing this, a typical business owner often faces this roadblock:

Why 3rd-Party User Authentication?

If you’re a big company with the necessary infrastructure to ensure data security and compliance, then you probably don’t need a 3rd-party solution.

But it’s quite the opposite if:

• This isn’t your domain of expertise.
• You’re a startup or simply can’t bear the financial overhead.
• You can’t ensure the proper data management and security.
• A data breach can break your organization.

So, don’t make pizza if you aren’t Dominos. Chances are you’ll spoil it.

But since user data is a lot more serious than wasting a pepperoni pizza, let’s check out some user authentication platforms. And while an average business person will straightaway run towards Auth0 or Firebase, there are others as well.
