For an internal admin product, the usual answer is:
Use your company’s existing Identity Provider via SSO
Most teams should centralize login with SAML or OIDC (OpenID Connect) against an IdP like:
- Google Workspace / Cloud Identity
- Microsoft Entra ID (Azure AD)
- Okta
- OneLogin
- Ping Identity
- Auth0 / Okta Customer Identity if you need a managed auth layer
Best default choice
If you’re building this from scratch, the safest default is:
- OIDC for modern apps
- SAML only if you need compatibility with enterprise IdPs or existing SSO setups
Typical setup for an internal admin tool
- User opens admin app
- App redirects to IdP login
- IdP authenticates user
- App receives identity token / assertion
- App maps user to internal roles/groups
- App enforces access based on role/permission
What to use depends on your environment
If you already use Google Workspace or Microsoft 365
Use:
- Google OIDC
- Microsoft Entra ID OIDC
If you want enterprise-grade access control
Use:
- Okta or Entra ID
- Add group-based authorization in your app
If you want a managed auth product
Use:
- Auth0 or Clerk
- Good for faster implementation, but often more than needed for purely internal tools
Recommendation
For most internal admin products:
- Authenticate with OIDC SSO
- Authorize with internal roles synced from IdP groups
- Require MFA through the IdP
- Do not build your own password system
If you want a very simple starting point
If your organization is already on:
- Google Workspace → use Google OIDC
- Microsoft → use Entra ID
- Okta → use Okta OIDC
If you want, I can help you choose the best option based on your stack and company setup, or sketch a recommended architecture for login + RBAC.
