Auth0 vs Cognito

Learn why developers prefer Auth0 for its ease of use, extensibility, security, migration and deployment options.

Auth0 provides the most universal solution for developers, supporting more than 40 different development stacks covering just about every development language or platform currently being developed on.

Additionally, each SDK comes with a seed project and tutorial, both with live documentation, meaning your account information is pre-populated, so you just copy and paste working code from the documentation into your app.

Cognito only has Android, iOS, Javascript, Unity, and Xamarin SDKs. For enterprise federation, they don’t have AD/LDAP or a majority of enterprise IdPs, whereas Auth0 has a real-time AD/LDAP integration, as one of 10 enterprise IdPs immediately available.

“In an hour, I was able to prove this thing would work the way I wanted it to. That kind of productivity really sold me as well. I didn’t have to write difficult code for every IdP we needed to integrate with. It was just writing one thing, very simple, and that was it to implement secure authentication.”

— David Bernick, Director of Technology, Harvard Medical School Department of Bioinformatics

Extensibility: fully customize auth

Auth0’s Rules functionality allows you to write Javascript code directly in the dashboard to customize the authentication and authorization pipeline. For example, you can whitelist email verification domains or block logins based on fraud indicators.

Auth0’s extensions allows you to ratchet on custom applications and functionality on top of our platform. This extensibility will ensure that any custom requirements can always be met.

Cognito has Lambda Triggers but it cannot be configured right in your browser, and they don’t provide as many templates to use right out of the box.

Extra security without writing additional code

Auth0 provides multi-factor authentication, anomaly detection and brute force protection just with the flip of a switch, to safeguard against fraudulent activity like brute force attacks and customers using previously breached passwords.

Cognito just has a one-size-fits-all SMS based MFA, while Auth0 provides a variety of MFA options: Push, SMS, Magic Link, Touch ID, Google Authenticator, Duo Security, and even the ability to build your own authenticator with Guardian.

“Before any news sites reported on last year’s Heartbleed zero day vulnerability, Auth0 emailed us to alert us to the situation. There was already a patch to eliminate the Heartbleed threat from Auth0’s systems, followed by a confirmation email that Auth0 had already installed this patch on the Schneider Electric instance of Auth0’s service. Auth0 helps our platform team look really good.”

Deploy Anywhere

Auth0 can be deployed virtually anywhere, our multi-tenant standard cloud offering, a private cloud offering that Auth0 hosts, on your cloud environment or on your on-premises environment.

Cognito only allows you to deploy in AWS pubic cloud, while Auth0 supports on-prem, managed hosting and public cloud.

“Compared to the costs and resources required to build, host, and secure a custom solution, the investment associated with a third-party authentication service like Auth0 was a sensible choice.”

— Cris Concepcion, Engineering Manager, Safari Books Online

Custom Databases & Migrations

Auth0 supports JIT migrations out of the box while with Cognito, you would have to do a bulk migration or code JIT. In addition to providing you with a free Auth0 username/password database, we can also connect to any user store (API or database). Your users will not have to reset passwords if you choose to migrate over.
