Authentication & Account Management Platform
Versola centralizes authentication, authorization, and account management, enabling teams to quickly build secure systems without developing their own identity infrastructure. OAuth 2.0 and OpenID Connect compliant.
Everything you need to manage identity and access
A single source of truth for your entire ecosystem. Centralize account management and enable Single Sign-On (SSO) across all your applications. Versola acts as a robust OAuth 2.0 and OpenID Connect provider, ensuring consistent identity governance and simplified user lifecycle management.
Centralized management of your OAuth 2.0 clients and scopes. Register web apps, mobile apps, and server-to-server integrations. Define custom scopes, permissions, and control which clients can request which resources. Rotate secrets, configure authentication challenges and authorization request presets.
Support multiple authentication factors out of the box. Users can authenticate with passwords, one-time codes (OTP) sent via external providers, or passkeys (WebAuthn). Mix and match authentication methods per OAuth client, integrate with your OTP delivery services, and enforce step-up authentication when accessing sensitive resources.
Dynamic permissions powered by Google's CEL. Define sophisticated access rules that go beyond static roles. Using the Common Expression Language (CEL), Versola allows you to write fine-grained policies that evaluate user attributes, authorization details, and real-time request data for true Zero Trust security.
Built on OAuth 2.1 and OpenID Connect specifications. PKCE enforced, refresh token rotation enabled, secure token storage. No deprecated flows (Implicit, ROPC). Future-proof your auth infrastructure with industry-standard protocols.
Direct user and access management
Create, update, and search for users. Manage identity attributes, perform manual password resets, view and delete registered passkeys.
View active sessions for a specific user with metadata (user agent, authentication methods). Force-terminate sessions to instantly revoke access when an account is compromised.
Define roles and map them to resource endpoints. Assign or revoke roles for specific users within a tenant.
Versola automatically blocks suspicious activity through rate limiting. Administrators can manually reset blocks for legitimate users.
Scala 3 type safety eliminates entire classes of runtime errors at compile time. ZIO runtime delivers high-performance, resilient concurrent execution. PostgreSQL provides proven reliability, ACID guarantees, and mature tooling ecosystem.
Deploy in your infrastructure with Docker. Built-in observability: metrics, structured logging, health checks, graceful shutdown. Scales horizontally as your needs grow.
OAuth 2.1 and OpenID Connect compliance from day one. Security by design, transparent development, and long-term architectural decisions that minimize future migration costs.
Built by developers, for developers. We focus on making integration straightforward and maintainable, so your team can ship faster without fighting the auth layer.
Deploy in your infrastructure, maintain complete data ownership. Community License available for internal authentication. Build your security posture on a foundation you control.
Open development process with source-available code. We listen to community feedback, maintain a public roadmap, and believe in transparent communication about features, limitations, and future direction.
