Identity infrastructure for software that cannot fail
Authr is the enterprise identity layer — single sign-on, directory sync, adaptive MFA, and fine-grained authorization. 5.2 billion authentications a month. 99.999% uptime, in the contract.
Trusted by the enterprises your enterprise trusts
Everything identity. Nothing improvised.
Six systems, one fabric. Each one deep enough to be a product; together, the identity layer your security review has been asking for.
Your identity program, on one pane of glass
Every organization, connection, policy, and session — observable and governable from a console your IT admins will actually enjoy.
A decade of identity edge cases, behind one clean API
SDKs for every stack your teams run, tokens signed with EdDSA and rotated without downtime, JWKS cached at 34 edge regions. The standards, implemented the way the RFC authors intended.
- OIDC-certified endpoints, PKCE enforced by default
- First-class SDKs: TypeScript, Python, Go, Java, Ruby, .NET
- Zero-downtime signing key rotation, automated quarterly
- Drop-in components or headless — your UI, your rules

Built by people who assume they're being attacked
Identity infrastructure is the highest-value target on the internet. We operate accordingly — and publish how.
Encryption without exceptions
AES-256-GCM at rest, TLS 1.3 in transit, EdDSA-signed tokens. Keys live in HSMs and rotate on a zero-downtime schedule.
Adversarial by default
Continuous red-team engagements, quarterly third-party penetration tests, and a public bug bounty with a 24-hour triage SLA.
Blast-radius engineering
Cell-based isolation per customer tier. A failure in one cell cannot reach another — by architecture, not by policy.
Humans removed from the loop
Production access is just-in-time, peer-approved, hardware-key gated, and recorded. Standing credentials don't exist here.
Closer to your users than their own data center
Token issuance, session checks, and policy decisions run in 34 edge regions. Your users authenticate against the metal nearest to them — not a region on the other side of an ocean.
We migrated 84,000 employees and 130 federated partners off a homegrown SSO stack in eleven weeks. Auth incidents since: zero. Our board asked why we didn't do it years ago.
Notes from the people holding the keys
