Auth0 vs Authy: What are the differences?
Auth0: Token-based Single Sign On for your Apps and APIs with social, databases and enterprise identities. A set of unified APIs and tools that instantly enables Single Sign On and user management to all your applications; Authy: The easiest way to add Two-Factor Authentication to any website or app. We make the best rated Two-Factor Authentication smartphone app for consumers, a Rest API for developers and a strong authentication platform for the enterprise.
Auth0 belongs to "User Management and Authentication" category of the tech stack, while Authy can be primarily classified under "Security".
Some of the features offered by Auth0 are:
- User and Password support with verification and forgot password email workflow
- Painless SAML Auth with Enterprises
- Integration with 20+ Social Providers
On the other hand, Authy provides the following key features:
- Very secure- We take security seriously. We use industry standard secure algorithms (HMAC RFC 4426) and 256 bits keys which are always encrypted at rest.
- Fully redundant- The Authy API is deployed accross different PCI level 1 data-centers and it's fully redundant. We also use a DNS provider with anycast support. We've had 100% availability since 2011.
- Great user experience- You connect to Authy using a transparent REST API which allows you to customize the experience you want for your users.
Binary.com, Cofounders Pte Ltd, and Vizzbuzz are some of the popular companies that use Auth0, whereas Authy is used by Twitch, Chargify, and Coinbase. Auth0 has a broader approval, being mentioned in 121 company stacks & 53 developers stacks; compared to Authy, which is listed in 18 company stacks and 5 developer stacks.
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!
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.
