Auth0 vs Authy: What are the differences?

Introduction

Auth0 and Authy are two popular authentication and authorization platforms that provide security and identity management solutions. While both offer similar functionalities, there are several key differences between Auth0 and Authy.

  1. Integration and Customization: Auth0 provides more flexibility in terms of integration and customization. It offers a wide range of SDKs and libraries, making it easier to integrate with various platforms and technologies. Auth0 also allows for extensive customization of workflows, user interface, and branding. On the other hand, Authy focuses more on simplicity and ease of use, providing a more out-of-the-box solution with less customization options.

  2. Multi-Factor Authentication (MFA): Authy is primarily focused on providing MFA solutions, offering token-based authentication through SMS, voice, and push notifications. It offers a simple and user-friendly MFA experience with features like device recognition and backup options. Auth0, on the other hand, provides MFA as one of its many features but has a broader scope in terms of authentication and authorization capabilities.

  3. Enterprise Scale and Support: Auth0 is well-suited for enterprise-scale deployments and offers extensive support and documentation for complex use cases. It provides features like anomaly detection, risk-based authentication, and fine-grained access control policies that cater to the needs of large organizations. Authy, while capable of handling small to medium scale deployments, may not offer as advanced enterprise features or comprehensive support.

  4. User Management and Administration: Auth0 provides a comprehensive user management system that allows for easy user onboarding, user profile management, password reset, and user permissions. It also supports social login and identity federation. Authy, on the other hand, focuses more on the authentication aspect and may not offer the same level of user management and administration functionalities as Auth0.

  5. Authentication Protocols and Standards: Auth0 supports a wide range of authentication protocols and standards including OpenID Connect, OAuth 2.0, SAML, and more. It allows for seamless integration with third-party applications and services. Authy, while also supporting some authentication protocols, may have a more limited range of options.

  6. Pricing and Licensing: Auth0 offers a flexible pricing structure with various plans based on usage and requirements. It provides a free tier and options for custom enterprise plans. Authy, on the other hand, offers a paid service and may not have as many pricing options or flexibility.

In summary, Auth0 provides more integration options, customization capabilities, and advanced enterprise features, while Authy focuses on providing a simple and user-friendly MFA solution. The choice between Auth0 and Authy depends on the specific requirements and priorities of the organization or project.

PassportPassport

Currently, Passport.js repo has 324 open issues, and Jared (the original author) seems to be the one doing most of the work. Also, given that the documentation is not proper. Is it worth using Passport.js?

As of now, StackShare shows it has 29 companies using it. How do you implement auth in your project or your company? Are there any good alternatives to Passport.js? Should I implement auth from scratch?

I would recommend Auth0 only if you are willing to shell out money. You can keep up with their free version only for a very limited time and as per our experience as a growing startup where budget is an issue, their support was not very helpful as they first asked us to sign a commercial agreement even before helping us t o find out whether Auth0 fits our use case or not! But otherwise Auth0 is a great platform to speed up authentication. In our case we had to move to alternatives like Casbin for multi-tenant authorization!

Decisions about Auth0 and Authy

from
Amazon CognitoAmazon Cognito
to
Auth0Auth0

I started our team on Amazon Cognito because I was a Solutions Architect at AWS and found it really easy to follow the tutorials and get a basic app up and running with it.

When our team started working with it, they very quickly became frustrated because of the poor documentation. After 4 days of trying to get all the basic passwordless auth working, our lead engineer made the decision to abandon it and try Auth0... and managed to get everything implemented in 4 hours.

The consensus was that Cognito just isn't mature enough or well-documented, and that the implementation does not cater for real world use cases the way that it should. I believe Amplify has made some of this simpler, but I would still recommend Auth0 as it's been bulletproof for us, and is a sensible price.
