Auth0 vs AWS IAM: What are the differences?

Developers describe Auth0 as "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. On the other hand, AWS IAM is detailed as "Securely control access to AWS services and resources for your users". AWS Identity and Access Management.

Auth0 belongs to "User Management and Authentication" category of the tech stack, while AWS IAM can be primarily classified under "Cloud Access Management".

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, AWS IAM provides the following key features:

  • Manage IAM users and their access - You can create users in IAM, assign them individual security credentials (i.e., access keys, passwords, and Multi-Factor Authentication devices) or request temporary security credentials to provide users access to AWS services and resources.
  • Manage IAM roles and their permissions - You can create roles in IAM, and manage permissions to control which operations can be performed by the entity, or AWS service, that assumes the role. You can also define which entity is allowed to assume the role.
  • Manage federated users and their permissions - You can enable identity federation to allow existing identities (e.g. users) from your corporate directory or from a 3rd party such as Login with Amazon, Facebook, and Google to access the AWS Management Console, to call AWS APIs, and to access resources, without the need to create an IAM user for each identity.

"JSON web token" is the top reason why over 47 developers like Auth0, while over 21 developers mention "Centralized powerful permissions based access" as the leading cause for choosing AWS IAM.

9GAG, Splunk, and Obama for America Campaign 2012 are some of the popular companies that use AWS IAM, whereas Auth0 is used by, Cofounders Pte Ltd, and Vizzbuzz. AWS IAM has a broader approval, being mentioned in 132 company stacks & 48 developers stacks; compared to Auth0, which is listed in 121 company stacks and 53 developer stacks.

    Auth0 seems like the most viable way to have full-fledged user management in AWS without too much hassle. Aside of being paid, it offers many advantages, such as social network logins or handy administration interface.

    Authentication as a service. Instead of rolling our own user authentication flow for yet another time, it's better to leave the security concern to a service specialized in this field.

    Easy privilege segregation. Instance roles let you easily set privileges for a particular Stack (Rails/DB/backup worker)
