Why It Matters
Logto is one of few platforms that offers genuine choice between cloud-managed and self-hosted deployment without feature restrictions. Built on OAuth 2.1 and OIDC standards, it provides protocol-compliant identity infrastructure with token-based pricing on cloud — 50K free tokens, then $0.08/100 extra.
What It Actually Does
Every capability explained in plain English — so you know exactly how Logto handles authentication, user management, and security for your product.
Omni Sign-In Experience
Multi-app and cross-domain sign-in with a beautiful, customizable hosted UI. Password, passwordless (email/SMS), social login, enterprise SSO, and MFA — all from one unified experience. Custom CSS, bring-your-own-UI option, app logo, favicon, and dark mode support.
One beautiful login page that automatically handles passwords, social login, enterprise SSO, and two-factor auth. Customize it with your brand or build your own UI entirely.
Organizations (Multi-Tenancy)
Multi-tenant organization management with custom roles and permissions per org, member invitations via Management API, JIT (just-in-time) provisioning, and organization-level MFA enforcement. Unlimited organizations and users per org on Pro plan.
Build SaaS products where each business customer gets their own space with team management, roles, and permissions. New users are automatically provisioned when they sign in.
Enterprise SSO (SAML & OIDC)
Enterprise SSO add-on supporting SAML 2.0 and OIDC identity providers. Connect Okta, Azure AD, Google Workspace, and any compliant IdP. $48/connector/month on Pro plan.
Enterprise customers log in through their company identity provider. Logto supports all major providers and handles the complex SAML/OIDC protocols for you.
Machine-to-Machine Auth
M2M application type for service-to-service authentication via OAuth 2.0 Client Credentials flow. 1 M2M app included on Free, additional at $8/each on Pro. API resources with scoped permissions.
Secure communication between your backend services and APIs. Logto handles API keys and permissions for server-to-server communication alongside human user auth.
Security & Standards Compliance
Built on OAuth 2.1 and OIDC standards. PKCE, CSRF protection, DoS protection (Cloudflare + Azure firewall), OIDC back-channel logout, signing key rotation, and password policy configuration. SOC 2 Type II certified.
Logto follows the latest security standards (OAuth 2.1) and is independently audited (SOC 2 Type II). Security isn't bolted on — it's how the system is designed.
User Management & Account API
Full user management console with search, edit, suspend, and delete capabilities. Account API for building custom account settings interfaces. Personal access tokens, user impersonation, and custom profile fields.
A dashboard to manage all your users — search accounts, reset passwords, suspend bad actors. Plus APIs for building custom account settings pages in your app.
Advanced Security Bundle (Add-On)
Optional security add-on ($48/month on Pro): CAPTCHA/bot protection, identifier lockout (brute-force protection), disposable email blocking, sub-email blocking, and email blocklist. Available as a bundled add-on.
Extra security features that block bots, prevent brute-force attacks, and reject disposable email addresses — available as an optional upgrade.
Webhooks & Audit Logs
Real-time webhook events for authentication and user lifecycle events. Audit log retention (3 days free, 14 days Pro). Custom token claims for enriching JWTs with application-specific data.
Get notified in real time when users sign up, log in, or change their accounts. Full audit trail for compliance and debugging.
Why Teams Choose Logto
The key advantages that make Logto stand out for authentication and user management.
Genuine Open Source (MPL-2.0)

Under the Hood
A plain-language breakdown of what Logto can and can't do — so you know exactly what you're getting.
Email & Password
Traditional username/password login with automatic password hashing and breach detection.
Magic Links
Passwordless login via email — click a link insted of typing a password.
Social SSO
One-click login with Google, GitHub, Apple, and other social accounts your users already have.
Passkeys / WebAuthn
Biometric login (fingerprint, Face ID) — the most secure and convenient authentication method available.
Passwordless Login
SMS codes, email OTPs, and other methods that eliminate passwords entirely.
Multi-Factor Auth (MFA)
Require a second verification step — even if a password is compromised, the account stays protected.
TOTP (Authenticator Apps)
Support for Google Authenticator, Authy, and other time-based one-time password apps.
SMS OTP
One-time passcodes sent via text message for verification or as a second factor.
Bot Protection
Machine-learning detection to block fake sign-ups, disposable emails, and automated abuse.
Rate Limiting
Automatic throttling of login attempts to prevent brute-force attacks.
Enterprise SSO
Let enterprise customers log in through their corporate identity provider (Okta, Azure AD, Google Workspace).
SAML 2.0
Industry-standard protocol for enterprise single sign-on — required by most large organizations.
OpenID Connect (OIDC)
Modern identity layer on top of OAuth 2.0 — used by Google, Microsoft, and most identity providers.
Audit Logs
A record of who signed in, when, and from where — essential for compliance and security monitoring.
User Management Dashboard
Admin panel to view, search, edit, ban, and manage all your users without writing code.
Organization Management
Multi-tenant team workspaces — create orgs, invite members, assign roles, and manage billing per org.
Role-Based Access Control
Define custom roles (admin, editor, viewer) with fine-grained permissions for who can do what.
Multi-Tenancy
Isolate data and configuration per organization — essential for B2B SaaS products.
User Impersonation
Log in as any user to debug issues or provide support — without asking for their password.
Pre-Built UI Components
Drop-in sign-up, sign-in, profile, and org management components — ship auth UI in minutes, not weeks.
Custom UI / Headless
Build your own login UI from scratch using the API directly — full design freedom.
Webhooks
Real-time notifications when users sign up, update profiles, or change organizations.
Session Management
Automatic token rotation, device tracking, and configurable session lifetimes.
Machine-to-Machine (M2M)
API keys and service tokens for server-to-server communication without a human user.
Custom Domains
Host the auth flow on your own domain — no redirects to a third-party login page.
Custom Claims / Metadata
Attach arbitrary data to user tokens — roles, plan type, feature flags — accessible in every API request.
Full-Stack Frameworks
Frameworks where the SDK handles both server and client — middleware, SSR helpers, and edge runtime.
Frontend Libraries
Client-side SDKs for building custom auth UIs in single-page apps and browser extensions.
Backend SDKs
Server-side libraries for token verification, user management, and webhook handling.
Mobile SDKs
Native and cross-platform SDKs for iOS, Android, and React Native apps.
Deployment Model
Where the service runs. Cloud-only = fully managed; Self-hosted = you run it; Hybrid = both options.
License
Whether the code is open source or proprietary. Open source means no vendor lock-in.
Founded
When the company or project was started — indicates maturity and track record.
Maintained By
The company or community behind the project.
Social Login Providers
One-click social sign-on providers supported by Logto — let your users log in with accounts they already have.
12 providers supported. Custom OAuth2/OIDC providers can also be configured.
Best For
Product types and use cases where Logto delivers the most value — based on its feature set, compliance story, and multi-tenant capabilities.
SaaS & Multi-App Products
Omni sign-in enables single identity across multiple apps and domains. Organizations with RBAC handle multi-tenancy. OIDC/SAML app support lets Logto serve as your own identity provider.
Privacy-Sensitive Products
Self-hosted option for full data sovereignty. Cloud available in EU, US, AU, and JP regions. SOC 2 Type II certified. Data isolation and encryption at rest. No vendor lock-in with open-source core.
Developer Platforms
M2M auth, personal access tokens, OIDC/OAuth third-party apps, and a comprehensive Management API make Logto ideal for platforms that need to issue auth to third parties.
Enterprise (Self-Hosted)
Self-hosted Docker deployment with enterprise SSO, SAML apps, and organizations. However, self-hosted version requires your own infrastructure team for maintenance and scaling.
Startups & MVPs
50K MAU free on cloud, unlimited on self-hosted. Token-based pricing is affordable. However, the add-on pricing model (MFA $48, RBAC $32, Organizations $48) can add up quickly.
Consumer Apps
Social login, passwordless, and beautiful sign-in UI cover consumer needs. Mobile SDKs for React Native, Flutter, iOS, and Android. Token-based pricing scales predictably.

Honest Trade-Offs
No technology is perfect. Here are the real limitations of Logto — so you make an informed decision, not a surprised one.
| Trade-Off | Impact | Details |
|---|---|---|
| Add-On Pricing Adds Up Quickly | High | MFA ($48), RBAC ($32), Organizations ($48), Enterprise SSO ($48/connector), and Advanced Security ($48) are all separate add-ons. A fully-featured Pro setup can easily exceed $200/month before token costs. |
| No Passkey Support Yet | Medium | Passkey/WebAuthn as a first-factor authentication method is listed as 'coming soon.' In a market where Clerk, WorkOS, and Better Auth already support passkeys, this is a notable gap. |
| Token-Based Pricing Complexity | Medium | Pricing is based on tokens (access tokens) rather than straightforward MAU. Understanding how tokens relate to actual users requires consulting documentation — less intuitive than per-user pricing. |
| Self-Hosted Requires Docker Expertise | Medium | Self-hosted deployment via Docker is powerful but requires infrastructure knowledge. Database management, TLS configuration, and scaling are your responsibility. |
| Smaller Ecosystem Than Auth0/Clerk | Low | With 9K GitHub stars and a growing community, Logto's ecosystem is smaller than Auth0 or Clerk. Fewer third-party tutorials, Stack Overflow answers, and community resources. |
| No Built-In Rate Limiting | Low | Unlike Clerk or Better Auth, Logto doesn't include built-in rate limiting for authentication endpoints. You rely on Cloudflare/Azure firewall protections or implement rate limiting in your infrastructure. |
