Work in Open Source, Ory is hiring!

Ory Kratos is the developer-friendly, security-hardened and battle-tested Identity, User Management and Authentication system for the Cloud. Finally, it is no longer necessary to implement User Login for the umpteenth time!

Ory Kratos on the Ory Network

The Ory Network is the fastest, most secure and worry-free way to use Ory's Services. Ory Identities is powered by the Ory Kratos open source identity server, and it's fully API-compatible.

The Ory Network provides the infrastructure for modern end-to-end security:

• Identity & credential management scaling to billions of users and devices
• Registration, Login and Account management flows for passkey, biometric, social, SSO and multi-factor authentication
• Pre-built login, registration and account management pages and components
• OAuth2 and OpenID provider for single sign on, API access and machine-to-machine authorization
• Low-latency permission checks based on Google's Zanzibar model and with built-in support for the Ory Permission Language

It's fully managed, highly available, developer & compliance-friendly!

• GDPR-friendly secure storage with data locality
• Cloud-native APIs, compatible with Ory's Open Source servers
• Comprehensive admin tools with the web-based Ory Console and the Ory Command Line Interface (CLI)
• Extensive documentation, straightforward examples and easy-to-follow guides
• Fair, usage-based pricing

What is Ory Kratos?

Ory Kratos is an API-first Identity and User Management system that is built according to cloud architecture best practices. It implements core use cases that almost every software application needs to deal with:

• Self-service Login and Registration: Allow end-users to create and sign into accounts (we call them identities) using Username / Email and password combinations, Social Sign In ("Sign in with Google, GitHub"), Passwordless flows, and others.
• Multi-Factor Authentication (MFA/2FA): Support protocols such as TOTP (RFC 6238 and IETF RFC 4226 - better known as Google Authenticator)
• Account Verification: Verify that an E-Mail address, phone number, or physical address actually belong to that identity.
• Account Recovery: Recover access using "Forgot Password" flows, Security Codes (in case of MFA device loss), and others.
• Profile and Account Management: Update passwords, personal details, email addresses, linked social profiles using secure flows.
• Admin APIs: Import, update, delete identities.

We highly recommend reading the Ory Kratos introduction docs to learn more about Ory Krato's background, feature set, and differentiation from other products.

Getting Started

To get started with some easy examples, head over to the Get Started Documentation.

Installation

Head over to the Ory Developer Documentation to learn how to install Ory Kratos on Linux, macOS, Windows, and Docker and how to build Ory Kratos from source.

Ecosystem

We build Ory on several guiding principles when it comes to our architecture design:

• Minimal dependencies
• Runs everywhere
• Scales without effort
• Minimize room for human and network errors

Ory's architecture is designed to run best on a Container Orchestration system such as Kubernetes, CloudFoundry, OpenShift, and similar projects. Binaries are small (5-15MB) and available for all popular processor types (ARM, AMD64, i386) and operating systems (FreeBSD, Linux, macOS, Windows) without system dependencies (Java, Node, Ruby, libxml, ...).

Ory Kratos: Identity and User Infrastructure and Management

Ory Kratos is an API-first Identity and User Management system that is built according to cloud architecture best practices. It implements core use cases that almost every software application needs to deal with: Self-service Login and Registration, Multi-Factor Authentication (MFA/2FA), Account Recovery and Verification, Profile, and Account Management.

Ory Hydra: OAuth2 & OpenID Connect Server

Ory Hydra is an OpenID Certified™ OAuth2 and OpenID Connect Provider which easily connects to any existing identity system by writing a tiny "bridge" application. It gives absolute control over the user interface and user experience flows.

Ory Oathkeeper: Identity & Access Proxy

Ory Oathkeeper is a BeyondCorp/Zero Trust Identity & Access Proxy (IAP) with configurable authentication, authorization, and request mutation rules for your web services: Authenticate JWT, Access Tokens, API Keys, mTLS; Check if the contained subject is allowed to perform the request; Encode resulting content into custom headers (X-User-ID), JSON Web Tokens and more!

Ory Keto: Access Control Policies as a Server

Ory Keto is a policy decision point. It uses a set of access control policies, similar to AWS IAM Policies, in order to determine whether a subject (user, application, service, car, ...) is authorized to perform a certain action on a resource.

Security

Running identity infrastructure requires attention and knowledge of threat models.

Disclosing vulnerabilities

If you think you found a security vulnerability, please refrain from posting it publicly on the forums, the chat, or GitHub. You can find all info for responsible disclosure in our security.txt.

Telemetry

Ory's services collect summarized, anonymized data that can optionally be turned off. Click here to learn more.

Documentation

Guide

The Guide is available here.

HTTP API documentation

The HTTP API is documented here.

Upgrading and Changelog

New releases might introduce breaking changes. To help you identify and incorporate those changes, we document these changes in the CHANGELOG.md. For upgrading, please visit the upgrade guide.

Command line documentation

Run kratos -h or kratos help.

Develop

We encourage all contributions and encourage you to read our contribution guidelines

Dependencies

You need Go 1.16+ and (for the test suites):

• Docker and Docker Compose
• Makefile
• NodeJS / npm

It is possible to develop Ory Kratos on Windows, but please be aware that all guides assume a Unix shell like bash or zsh.

Install from source

make install

Formatting Code

You can format all code using make format. Our CI checks if your code is properly formatted.

Running Tests

There are three types of tests you can run:

• Short tests (do not require a SQL database like PostgreSQL)
• Regular tests (do require PostgreSQL, MySQL, CockroachDB)
• End to end tests (do require databases and will use a test browser)

Short Tests

Short tests run fairly quickly. You can either test all of the code at once

go test -short -tags sqlite ./...

or test just a specific module:

cd client; go test -tags sqlite -short .

Regular Tests

Regular tests require a database set up. Our test suite is able to work with docker directly (using ory/dockertest) but we encourage to use the Makefile instead. Using dockertest can bloat the number of Docker Images on your system and are quite slow. Instead we recommend doing:

make test

Please be aware that make test recreates the databases every time you run make test. This can be annoying if you are trying to fix something very specific and need the database tests all the time. In that case we suggest that you initialize the databases with:

make test-resetdb
export TEST_DATABASE_MYSQL='mysql://root:secret@(127.0.0.1:3444)/mysql?parseTime=true'
export TEST_DATABASE_POSTGRESQL='postgres://postgres:secret@127.0.0.1:3445/kratos?sslmode=disable'
export TEST_DATABASE_COCKROACHDB='cockroach://root@127.0.0.1:3446/defaultdb?sslmode=disable'

Then you can run go test as often as you'd like:

go test -tags sqlite ./...

# or in a module:
cd client; go test  -tags sqlite  .

Updating Test Fixtures

Some tests use fixtures. If payloads change, you can update them with:

make test-update-snapshots

This will only update the snapshots of the short tests. To update all snapshots, run:

UPDATE_SNAPSHOTS=true go test -p 4 -tags sqlite ./...

You can also run this command from a sub folder.

End-to-End Tests

We use Cypress to run our e2e tests.

⚠️ To run Cypress on ARM based Mac's, at the moment it is necessary to install Rosetta 2. To install, use the command - softwareupdate --install-rosetta --agree-to-license

The simplest way to develop e2e tests is:

./test/e2e/run.sh --dev sqlite

You can run all tests (with databases) using:

make test-e2e

For more details, run:

./test/e2e/run.sh

Run only a singular test

Add .only to the test you would like to run.

For example:

it.only('invalid remote recovery email template', () => {
    ...
})

Run a subset of tests

This will require editing the cypress.json file located in the test/e2e/ folder.

Add the testFiles option and specify the test to run inside the cypress/integration folder. As an example we will add only the network tests.

"testFiles": ["profiles/network/*"],

Now start the tests again using the run script or makefile.

Build Docker

You can build a development Docker Image using:

make docker
