The 5 Best Amazon Cognito Alternatives

In the rapidly changing landscape of digital identity, the choice of the right auth provider is crucial for businesses. We understand, the idea of creating your own auth solution can be alluring. However, even if you decide to buy rather than build, you're met with a myriad of options.

Why Look for an Amazon Cognito Alternative?

Amazon Cognito is a well-liked customer identity and access management (CIAM) platform that offers authentication and authorization services for web and mobile apps. It brings to the table a wide range of features like Single Sign-On (SSO), multi-factor authentication (MFA), social logins, and more. Nevertheless, due to concerns about user pool limitations, token expiration times, and account recovery problems, developers have started seeking alternatives to Amazon Cognito.

The Top 5 Amazon Cognito Alternatives

We have discussed what Amazon Cognito brings to the table. But in the realm of auth providers, these are considered basic. Amazon Cognito offers SSO, MFA, and more... but so do all the other providers. These days, what distinguishes providers are factors, not features. Pricing, setup time, customization options, and migration alternatives all become significant in the decision to seek an alternative to Amazon Cognito.

These are the elements that this guide will concentrate on. In this guide, we'll provide a swift overview of each service. Yet, we'll also highlight their cost, setup times, and the requirements to get them up and running. It's also vital to be aware of Amazon Cognito security concerns, such as misconfigurations.

Auth0, or Okta Customer Identity, used to stand as a favored customer identity and access management (CIAM) platform offering services for web and mobile applications. Its broad range of features including Single Sign-On (SSO), multi-factor authentication (MFA), and social logins made it a solid choice.

Our Preference

Our preference for FusionAuth might be a tad partial, but for valid reasons. FusionAuth is designed by developers, for developers. So when you need assistance, you'll be talking with the creators of the product, not some low-tier support personnel. 

The challenge that several emerging providers within CIAM face is that their growth can become their Achilles heel. Take Okta's acquisition of Auth0. The hefty investment has led to increased costs for Auth0 customers, who now encounter steeper pricing, added expenses for features, and unreasonably strict Monthly Active User (MAU) limitations.

FusionAuth is VC free. To this day, our operation remains unswayed by investors. Our team is mainly composed of seasoned developers hailing from diverse backgrounds. We speak your language, and can help you build whatever you need.

User authentication is too critical a component to entrust to fate. While it is certainly possible to build it yourself, the complexity and the burden of ongoing maintenance could be daunting. Let us shoulder that responsibility. Join the Community plan today, and together, let's embark on the journey to build something truly remarkable.
