2. Comprehensive Feature Analysis

Logto provides a wide array of features covering user sign-in, security controls, and advanced identity management workflows.

2.1. User Sign-in Experience

The platform offers a variety of modern and traditional authentication methods designed to be frictionless for end-users.

2.2. Security and Access Control

Security is a central component of the Logto offering, with features designed for granular control and threat mitigation.

• Multi-Factor Authentication (MFA): Can be implemented in minutes, with support for:
  • WebAuthn (Passkeys)
  • Authenticator apps
  • Backup codes
• Role-Based Access Control (RBAC): Enables the creation of rules to control access to resources at both a global and an organization-specific level.
• Enterprise SSO: Streamlines integration with enterprise Identity Providers (IdPs) like Okta and Entra, as well as any generic SAML-based IdP, removing common integration “headaches.”

2.3. Advanced Authentication and Management Flows

Logto includes sophisticated features catering to complex SaaS and enterprise requirements.

• Multi-tenancy (Organizations): Allows applications to group users, manage resources, and apply specific permissions for different tenants (e.g., Business A, Business B).
• IdP for Third-Party Apps: An application using Logto can itself function as an Identity Provider (IdP) for an ecosystem of third-party apps, complete with a user-friendly consent flow.
• Machine-to-Machine (M2M) Authentication: Secures programmatic access for APIs, microservices, and devices.
• User Impersonation: A feature designed for customer support teams to safely impersonate end-users to troubleshoot and resolve issues quickly.
• Personal Access Tokens (PAT): Provides a mechanism for scripts, bots, and CI/CD pipelines to gain access without traditional user sign-in flows.
