Accounts, Login & Security

When your app has accounts, security isn’t optional. I implement modern authentication (email/password, magic links, SMS codes, passkeys, and SSO), role-based permissions, and strict data isolation so one customer can never see another’s data — the same patterns I use across multi-tenant platforms.

“I need real user accounts, but I’m nervous about doing security wrong.”

What's included

  • Email, magic-link, SMS-OTP & passkey login
  • SSO / OIDC for teams
  • Role-based access control (RBAC)
  • Strict per-tenant / per-user data isolation
  • Session management & audit trails

Where I've shipped it

Real client work that put this capability to use.
