OAuth 2.0 & OpenID Connect Provider
Standards-compliant OAuth and OIDC for modern applications. Authorization Code with PKCE, Client Credentials, refresh token rotation, and automatic discovery endpoints — all built with Rust for high-performance, low-latency operations.
Building OAuth Is Harder Than It Looks
OAuth 2.0 and OpenID Connect are powerful protocols, but implementing them correctly is notoriously difficult. A single misconfiguration can expose your entire user base.
- 1
Token management pitfalls
Insecure token storage, missing rotation, no replay detection, and weak signing algorithms lead to session hijacking and unauthorized access.
- 2
Redirect URI and CSRF vulnerabilities
Open redirects, missing state parameters, and improper redirect validation are among the most exploited OAuth flaws in production systems.
- 3
Spec compliance complexity
OAuth 2.0, PKCE, OIDC Core, OIDC Discovery, JWKS, token introspection, and revocation span dozens of RFCs. Partial implementations break interoperability.
- 4
Ongoing maintenance burden
Key rotation, certificate management, security patching, and keeping up with evolving best practices require dedicated engineering resources indefinitely.

Memory-safe, zero-garbage-collection architecture for fast, low-latency token issuance at scale.
Complete OAuth 2.0 & OIDC Feature Set
Everything you need to issue, validate, and manage OAuth tokens for your applications and APIs, without building any of it yourself.
Authorization Code + PKCE
Full support for the OAuth 2.0 Authorization Code flow with Proof Key for Code Exchange (PKCE). PKCE is enabled by default for all public clients, preventing authorization code interception attacks. Confidential clients can use standard code exchange with client secrets for server-to-server integrations.
Client Credentials Flow
Machine-to-machine authentication for backend services, microservices, and automated pipelines. Client credentials grant lets your servers authenticate directly without user interaction, ideal for service accounts, cron jobs, and internal API communication between trusted systems.
Refresh Token Rotation
Secure token lifecycle management with automatic refresh token rotation. Each time a refresh token is used, a new one is issued and the previous token is invalidated. This prevents replay attacks and limits the damage window if a token is compromised, keeping sessions secure over time.
OpenID Connect Discovery
Standards-compliant OIDC discovery endpoint at /.well-known/openid-configuration. Clients can automatically discover authorization endpoints, token endpoints, supported scopes, and signing algorithms without manual configuration, simplifying integration across any platform or language.
JWKS Endpoint
Publicly available JSON Web Key Set endpoint for token verification. Resource servers and API gateways can fetch your signing keys to validate access tokens locally without calling back to the authorization server, enabling fast, decentralized token validation at scale.
Scopes and Claims
Fine-grained access control through OAuth scopes and custom OIDC claims. Define exactly what each client can access, include organization-specific claims in ID tokens, and map roles and permissions directly into JWT payloads so your APIs can make authorization decisions from the token alone.
Why Choose TitaniumVault as Your OAuth Provider
A managed OAuth and OIDC provider that prioritizes security, performance, and developer experience from the first API call.
Standards-Compliant
Full conformance with RFC 6749 (OAuth 2.0), RFC 7636 (PKCE), and OpenID Connect Core 1.0. Your integration works with any OAuth/OIDC-compatible library, framework, or service out of the box. No proprietary extensions or vendor lock-in.
Secure by Default
PKCE is enforced for public clients. Tokens are signed with RSA-256. Refresh tokens rotate on every use. CORS is scoped per organization. Rate limiting protects token endpoints from abuse. Every default is chosen for security, not convenience.
Developer-Friendly
Well-documented REST APIs, OpenAPI 3.0 specification, and standard discovery endpoints mean your developers spend minutes integrating, not weeks. Works with every major OAuth library including NextAuth, Passport.js, Spring Security, and dozens more.
Fast Token Validation
RSA-signed JWTs allow resource servers to validate tokens locally using the public JWKS endpoint. No round-trip to the authorization server on every API call. Combined with our Rust-powered infrastructure, token issuance and introspection happen with low-latency response times.

Tokens exposed in URL fragments; deprecated by OAuth 2.0 Security BCP.
Resource Owner Password Credentials not supported
Requires sharing passwords with clients; deprecated by current security guidance.
PKCE enforced for public clients
Prevents authorization code interception on mobile and SPA clients.
Refresh tokens rotate on every use
Limits attack window if a refresh token is leaked.
Strict redirect URI matching
Exact-match only. No wildcards, no open redirects.
Frequently Asked Questions
Common questions about using TitaniumVault as your OAuth 2.0 and OpenID Connect provider.
What OAuth 2.0 grant types does TitaniumVault support?
TitaniumVault supports the Authorization Code grant with PKCE (recommended for all client types), the Client Credentials grant for machine-to-machine communication, and refresh token grants for maintaining long-lived sessions. We deliberately do not support the Implicit grant or Resource Owner Password Credentials grant, as both are considered insecure by current OAuth 2.0 Security Best Current Practice (RFC 9700). This keeps your implementation aligned with modern security standards from day one.
How does TitaniumVault handle token security and rotation?
Access tokens are signed with RSA-256 and include configurable expiration times. Refresh tokens use automatic rotation: each time a refresh token is exchanged for new tokens, the old refresh token is invalidated and a new one is issued. If a rotated-out refresh token is ever reused, TitaniumVault detects the replay and revokes the entire token family, immediately ending any compromised session. Token introspection is available for opaque token validation when needed.
Can I use TitaniumVault as the OAuth provider for my own SaaS application?
Yes. TitaniumVault is designed to serve as a full OAuth 2.0 authorization server and OpenID Connect provider for your applications. You register your applications as OAuth clients in the TitaniumVault dashboard, configure redirect URIs and scopes, and then your users authenticate through TitaniumVault. Your application receives standard OAuth tokens including ID tokens with user identity claims. This works for web apps, mobile apps, single-page applications, and backend services.
Does TitaniumVault support OpenID Connect discovery and JWKS?
Yes. TitaniumVault exposes a standards-compliant OpenID Connect Discovery document at the /.well-known/openid-configuration endpoint. This document advertises the authorization endpoint, token endpoint, userinfo endpoint, supported scopes, supported response types, and signing algorithms. The JWKS endpoint provides your RSA public keys so that any resource server or API gateway can validate tokens locally without contacting TitaniumVault on every request.
Is there a free tier that includes full OAuth and OIDC support?
Yes. The TitaniumVault free tier includes up to 5 staff users and 1,000 customer users with complete OAuth 2.0 and OpenID Connect functionality. There are no feature gates on the free plan: you get Authorization Code with PKCE, Client Credentials, refresh token rotation, OIDC discovery, JWKS endpoints, custom scopes, and organization-scoped OAuth clients. No credit card is required to sign up, and you can upgrade to a paid plan at any time as your usage grows.
