How to Migrate from Auth0 to TitaniumVault

Auth0 has been a popular choice for authentication, but the landscape has shifted. After Okta's acquisition, many teams are re-evaluating their auth provider. Whether you're concerned about pricing increases, vendor lock-in, or simply want a platform built for modern performance requirements, this guide walks you through every step of migrating from Auth0 to TitaniumVault with zero downtime.

Why Teams Are Leaving Auth0

Auth0 built a strong reputation as a developer-friendly authentication platform, but several factors are driving teams to look for alternatives:

Pricing Escalation After the Okta Acquisition

Since Okta acquired Auth0 in 2021, many customers have experienced significant price increases at renewal time. Auth0's free tier has become more restrictive, and enterprise plans have climbed steeply. Teams that started on Auth0 when it was affordable are now facing bills that don't align with the value they receive, especially as user counts grow. TitaniumVault offers transparent, predictable pricing that scales linearly without surprise jumps at tier boundaries.

Okta Acquisition Concerns

The Okta acquisition raised legitimate questions about Auth0's future direction. Product roadmaps have shifted toward Okta's enterprise-heavy strategy, and the developer-first philosophy that made Auth0 popular has taken a back seat. There have also been high-profile security incidents at Okta that have caused concern among Auth0 customers about the broader organization's security posture. Teams want an auth provider whose entire focus is on building the best authentication platform possible.

Performance and Modern Architecture

Auth0's infrastructure was built years ago and has accumulated significant technical debt. Token issuance latency, rate limits, and cold start times can be pain points at scale. TitaniumVault is built from the ground up in Rust, delivering fast, low-latency token operations, native connection pooling, and the kind of throughput that modern applications demand. If you're running at scale, the performance difference is measurable and meaningful.

Pre-Migration Audit: Know What You Have

Before touching any configuration, you need a complete inventory of your Auth0 setup. This audit prevents surprises during migration and ensures nothing gets left behind.

Log into your Auth0 dashboard and document the following:

• Tenants: List every tenant (development, staging, production). Note the region each tenant is deployed in and any custom domains configured.
• Applications: Document every application registered in Auth0, including client IDs, allowed callback URLs, allowed logout URLs, and grant types (authorization code, client credentials, implicit, etc.).
• Connections: Catalog all authentication connections: database connections, social providers (Google, GitHub, Microsoft, etc.), enterprise connections (SAML, OIDC, LDAP/AD), and passwordless options.
• Users: Record total user counts per connection and per tenant. Note any custom user metadata or app metadata you're storing.
• Rules, Actions, and Hooks: Export all Auth0 Rules (legacy), Actions, and Hooks. Document what each one does: adding custom claims, blocking certain users, enriching tokens, calling external APIs, etc.
• APIs and Resource Servers: List all APIs registered in Auth0 with their identifiers, scopes, and permissions.
• Roles and Permissions: Export your RBAC configuration, including all roles, the permissions assigned to each role, and user-role assignments.
• Email Templates: Save copies of all customized email templates (verification, password reset, welcome, MFA enrollment, etc.).
• Branding: Note any custom Universal Login page configurations, logos, colors, and custom HTML templates.

This audit document becomes your migration checklist. Every item must be accounted for in the new TitaniumVault setup before you cut over.

Step 1: Export Your Auth0 Configuration

Auth0 provides several ways to export your data. Use the Auth0 Management API or the Auth0 Deploy CLI to extract your configuration programmatically.

Export Users

Use the Auth0 Management API's export jobs endpoint to request a full user export. This produces a JSON file containing user profiles, email verification status, and metadata. Note that Auth0 does not export password hashes for database connections in a format that other providers can directly import. You have two options: perform a bulk password reset after migration, or use a progressive migration strategy where users are authenticated against Auth0 on first login and their credentials are captured in TitaniumVault going forward.

Export Application Configuration

For each application, record the client ID, client secret, application type (SPA, regular web app, native, machine-to-machine), allowed callback URLs, allowed logout URLs, allowed web origins, and any custom settings. Auth0's Deploy CLI can export this as code, making it easier to track changes and replicate in TitaniumVault.

Export Rules and Actions

Save every Rule and Action as a separate file with comments explaining its purpose. Rules are Node.js functions that run during the authentication pipeline. You'll need to understand what each one does to replicate the behavior in TitaniumVault's webhook and policy system. Common patterns include adding custom claims to tokens, blocking users based on IP or email domain, enriching user profiles from external databases, and triggering post-login workflows.

Step 2: Set Up Your TitaniumVault Organization

Create your TitaniumVault account and configure your organization to mirror your Auth0 setup.

1. Create your organization: Sign up at titanium-vault.com/register and create your organization. This is the top-level container equivalent to an Auth0 tenant.
2. Set up environments: Create separate environments for development, staging, and production, mirroring your Auth0 tenant structure. Each environment gets its own configuration, keys, and user pool.
3. Configure your custom domain: Set up your custom authentication domain (e.g., auth.yourcompany.com) in TitaniumVault. This is important for maintaining consistent URLs during migration so your users see a familiar domain.
4. Register your applications: Create application entries in TitaniumVault for each application you documented in the audit. Map the application types: Auth0's “Single Page Application” maps to TitaniumVault's SPA type, “Regular Web Application” maps to Web App, and “Machine to Machine” maps to Service type.
5. Define your APIs: Register each API resource server with its identifier and scopes. TitaniumVault uses the same audience/scope model as Auth0, so this mapping is straightforward.

Step 3: Migrate Connections and Social Providers

Authentication connections are the backbone of your identity system. Each connection type requires a slightly different migration approach.

Database Connections

TitaniumVault supports standard database connections with bcrypt password hashing. If you're migrating from an Auth0 database connection, the recommended approach is progressive migration. Configure TitaniumVault to attempt local authentication first, and if the user doesn't exist locally, proxy the authentication request to Auth0. On successful Auth0 authentication, TitaniumVault stores the user's credentials locally. Over time, all active users migrate automatically. Users who never log in during the migration window can be sent a password reset email.

Social Providers (Google, GitHub, Microsoft, etc.)

Social connections are the easiest to migrate because the credentials live with the identity provider, not with Auth0. For each social provider, create the same OAuth application (or reuse the existing one) and configure the client ID and secret in TitaniumVault. Update the authorized redirect URIs at the social provider to include your TitaniumVault callback URL. Users who signed in via social providers will simply re-authorize on their next login with no disruption to their experience.

Enterprise Connections (SAML, OIDC, LDAP/AD)

Enterprise connections require coordination with the identity provider administrator. For SAML connections, you'll need to update the Service Provider metadata (Entity ID, ACS URL, and signing certificate) at the identity provider to point to TitaniumVault instead of Auth0. For OIDC connections, update the redirect URIs. For LDAP/Active Directory, TitaniumVault provides its own LDAP sync agent that replaces Auth0's AD/LDAP connector. Install the TitaniumVault LDAP agent in your network and configure it to sync with your directory.

Step 4: Migrate Users

User migration is the most sensitive part of the process. TitaniumVault supports two approaches, and you can combine them.

Bulk Import

Take the user export from Auth0 and import it into TitaniumVault using the Management API's bulk import endpoint. This creates user records with profiles, email verification status, and metadata intact. Users imported this way will need to reset their password on first login (since Auth0 password hashes cannot be directly transferred) or you can use progressive migration for a seamless experience.

Progressive Migration (Recommended)

Progressive migration is the zero-downtime approach. Configure TitaniumVault as your primary authentication endpoint, but set up a fallback to Auth0 for users who haven't migrated yet. When a user logs in and doesn't exist in TitaniumVault, the system authenticates them against Auth0. If successful, it creates the user in TitaniumVault with their verified credentials. The user never notices anything has changed. Over a period of weeks, the vast majority of active users will migrate automatically. After your migration window closes, send password reset emails to any remaining users who haven't logged in.

Migrating User Metadata

Auth0 stores user data in two metadata buckets: user_metadata (user-editable) and app_metadata (application-controlled). Map these to TitaniumVault's user profile custom attributes. During bulk import, include the metadata fields in the import payload. During progressive migration, metadata is transferred when the user first authenticates through the migration proxy.

Step 5: Update Application Integrations

Your applications need to be updated to point to TitaniumVault instead of Auth0. The good news is that TitaniumVault implements standard OAuth 2.0 and OpenID Connect, so the changes are mostly configuration-level.

SDK and Library Changes

If you're using Auth0's SDKs (auth0-spa-js, auth0-react, nextjs-auth0, etc.), you'll replace them with standard OIDC libraries or TitaniumVault's SDK. In most cases, you're changing the issuer URL, client ID, and audience. The token format and claims structure remain standard JWT, so your backend token validation logic should require minimal changes. Update the authorization endpoint, token endpoint, and userinfo endpoint to TitaniumVault's URLs.

Backend Token Validation

Update your API servers to fetch the JWKS (JSON Web Key Set) from TitaniumVault's well-known endpoint instead of Auth0's. Update the expected issuer claim in your token validation middleware. If you're running both Auth0 and TitaniumVault in parallel during migration, configure your backend to accept tokens from both issuers temporarily.

Webhook and Rule Replacement

Auth0 Rules and Actions need to be replicated in TitaniumVault. Review each Rule from your audit and implement the equivalent logic using TitaniumVault's webhook system or built-in policy features. Common Auth0 Rule patterns and their TitaniumVault equivalents:

• Adding custom claims to tokens: Use TitaniumVault's token customization settings to add custom claims based on user attributes or roles.
• Blocking users by IP or domain: Use TitaniumVault's built-in IP allowlist/blocklist and email domain restrictions.
• Post-login API calls: Configure post-authentication webhooks to call your external services.
• User enrichment: Use TitaniumVault's pre-authentication hooks to fetch additional user data from external sources.

Step 6: Test Thoroughly

Testing is where migrations succeed or fail. Build a comprehensive test plan that covers every authentication flow your application supports.

• Login flows: Test every connection type (database, social, enterprise) with real accounts. Verify that login, logout, and session management work correctly.
• Token validation: Confirm that your backend APIs correctly validate tokens issued by TitaniumVault. Check that custom claims, scopes, and permissions are present and correct.
• MFA: If you use TOTP or WebAuthn with Auth0, verify that MFA enrollment and verification work in TitaniumVault. Users may need to re-enroll their MFA devices.
• Password reset: Test the full password reset flow including email delivery, link validity, and password update.
• User registration: Test new user signup to ensure it creates accounts correctly in TitaniumVault.
• Progressive migration: If using progressive migration, test that users who exist only in Auth0 can log in through TitaniumVault and are migrated seamlessly.
• Role-based access: Verify that roles, permissions, and authorization checks work correctly with TitaniumVault's RBAC system.
• Edge cases: Test account linking, email change, password change, session expiration, concurrent sessions, and refresh token rotation.

Run your full test suite in a staging environment that mirrors production. Perform load testing to ensure TitaniumVault handles your traffic patterns. Only proceed to the go-live step when every test passes.

Step 7: Go Live

With testing complete, it's time to cut over production traffic. Follow this sequence to ensure a smooth transition:

1. Enable progressive migration in production: If you're using progressive migration, enable it first so users start migrating before you fully cut over. Run both Auth0 and TitaniumVault in parallel for a defined period (typically two to four weeks).
2. Update DNS: If using a custom domain, update your DNS records to point your auth domain to TitaniumVault's servers. Use a short TTL in advance to make the switch faster.
3. Deploy application updates: Roll out the SDK and configuration changes to your applications. Use feature flags or gradual rollout if possible to limit blast radius.
4. Monitor closely: Watch error rates, login success rates, and latency metrics for the first 24-48 hours. TitaniumVault's dashboard provides real-time authentication analytics.
5. Handle stragglers: After your migration window closes, send password reset emails to users who haven't logged in yet. This ensures every user can access their account.
6. Decommission Auth0: Once all users have migrated and you're confident in the new setup, disable the Auth0 integration and cancel your Auth0 subscription. Keep your Auth0 data export archived for compliance purposes.

Conclusion

Migrating from Auth0 to TitaniumVault is a methodical process, not a risky one. With progressive migration, you can run both systems in parallel and move users over gradually with zero downtime. The key is thorough preparation: audit your Auth0 setup completely, test every flow in staging, and monitor closely after go-live.

Teams that have made the switch report lower authentication latency, simpler pricing, and a more focused developer experience. If your Auth0 renewal is coming up and the numbers don't make sense anymore, now is the time to evaluate your options.
