Recommendation

Route by lifecycle owner.

Authentication platforms, enterprise directories, B2B administration products, and application-owned user domains should not be treated as interchangeable.126

For: Teams defining user lifecycle and administrative ownership

Main trade-off

Delegating lifecycle operations couples identity records and synchronization boundaries to provider APIs.12

Lifecycle ownership models

Separate identity credentials from product profile data and enterprise provisioning.

  1. Source of truth

    Name the authoritative store for credentials, profile data, and employment or membership status.126

  2. Administration

    Decide whether product staff, customer admins, or enterprise directories create and deactivate users.35

  3. Lifecycle automation

    Determine whether invitations, suspension, deletion, and provisioning must be automated.36

  4. Domain depth

    Keep product-specific fields and workflows outside a generic identity profile when they carry business meaning.14

User-management routes

Choose the route that matches the authoritative lifecycle owner.

Integrated application identity

Use Clerk or Auth0 for the managed identity record while the application stores domain profile data.

This reduces authentication operations without forcing all product state into the identity provider.

Verify: Do not treat provider metadata as the full application data model.14

Enterprise directory lifecycle

Use WorkOS when customer directories and provisioning are the authority.

Directory-driven creation, updates, and deactivation need an enterprise identity integration boundary.

Verify: The application still owns product entitlements and domain state.36

B2B customer administration

Evaluate Frontegg when tenant admins need a broader packaged administration surface.

Tenant-oriented identity administration can reduce the work of building customer-facing management workflows.

Verify: Validate how far its tenant model matches the product domain.5

Application-owned lifecycle

Keep the domain user record in the application and integrate identity by stable subject ID.

This preserves control when onboarding, status, entitlements, or compliance workflows are product-specific.

Verify: The team owns administration, data quality, and lifecycle automation.6

Boundary: User management does not replace authentication, authorization, organization-domain modeling, or product entitlements.

What actually differs

The decisive difference is the owner of lifecycle state, not the number of profile fields.

Identity versus profile
Credential identity and session state are not the same as a product's user profile.14
Provisioning authority
Enterprise directories can become authoritative for activation and deactivation.36
Tenant administration
B2B products often need customer-admin workflows beyond basic identity records.15
Exit cost
More lifecycle state stored in a provider increases migration work.12

Official resources

Validate lifecycle, directory, and administration capabilities in current official documentation.
