Core Services
Everything your application needs
UII provides complete authentication infrastructure — designed for developers who need reliability, security, and speed without building it themselves.
Authentication
Email/password, magic links, passkeys, and 20+ OAuth providers. Pre-built UI components that match your brand. Drop-in sign-in flows that take minutes, not weeks.
User Management
Complete user lifecycle management — profiles, metadata, roles, and permissions. Full admin dashboard plus a programmatic API for every operation.
Multi-Factor Authentication
TOTP authenticator apps, SMS, email OTP, and hardware keys. Enforce MFA policies at the organization level with granular configuration options.
Organizations & Teams
Built-in multi-tenancy, team invites, org-level roles, and SSO support. Let your customers manage their own teams without custom backend code.
Webhooks & Events
Real-time event delivery for every auth action — user creation, sign-in, MFA changes, and more. Sync to your database or trigger downstream workflows instantly.
Analytics & Audit Logs
Detailed authentication analytics, suspicious activity detection, and immutable audit logs. Full compliance reporting with configurable retention policies.
Implementation
Integrate in three steps
From zero to production-ready authentication in under an hour. Our SDK handles the complexity — you ship the product.
01
Install the SDK
One package install. We support React, Next.js, Vue, Svelte, Express, and plain JavaScript. The CLI configures your environment automatically.
02
Configure your application
Set your API key, enable providers, and configure redirect URLs from your dashboard or a single config file. No complex OAuth flows to manage manually.
03
Manage users from day one
Your users appear instantly in the UII dashboard. Search, filter, manage roles, revoke sessions, and view audit logs — no custom admin UI required.
