Logto: Modern auth infrastructure for developers

Logto adds multi-tenancy, enterprise SSO, and RBAC to your SaaS or AI apps. All with OIDC and OAuth 2.1 made simple, fast, and developer-friendly.
OAuth 2.1, OIDC, SAML. Auth, SSO, RBAC.
From local to cloud. From web to mobile. From one app to many.
50K MAUs free. Token-based. Pay-as-you-go.
Open-source. Fast integration. Developer-first support.
Trusted by public companies, fast-growing startups, and government agencies.
Tired of duct-taping auth across your SaaS, AI agents, and B2B apps? Logto got you covered.
Passwordless that feels obvious: one-time codes via email or SMS.
Social sign-in, done. Google, Apple, Discord, and more.
At least 3 types of characters are required.
Still the default. Still what users expect.
One sign-in flow. Every app. Looks native. Works everywhere. Zero friction.
MFA in minutes. Passkeys, authenticator apps, backup codes.
Set rules, control access. RBAC for global and organization-level resources.
SSO with Okta, Entra, SAML, any IdP. Enterprise SSO without the enterprise headache.
Multi-tenancy that scales. Group users, manage resources, permission everything.
Your app. Your ecosystem. Be the IdP with a consent flow that doesn’t suck.
M2M made simple. APIs, microservices, devices, all locked down.
Troubleshoot like a hero. Safely impersonate users, fix issues fast.
