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.
