Sign-up, login, and the security basics done right
Authentication is deceptively easy to build badly. Password resets, email verification, session handling, and rate limiting all have to be correct, because a mistake here exposes every account. We build on established, battle-tested identity approaches instead of hand-rolling crypto.
The goal is a login experience that feels effortless to users while being genuinely hard to break — because the two are not in conflict when it's done properly.
- Secure password storage, email verification, and reset flows
- Social login (Google, Microsoft, and others) where it helps conversion
- Multi-factor authentication for accounts that need it
- Safe session management, secure cookies, and sensible timeouts
- Rate limiting and protection against credential-stuffing and brute force
- Proven identity libraries or providers rather than custom-built auth
Teams, roles, and SSO
Most SaaS products eventually need more than 'one user, one account.' Teams invite colleagues, admins manage members, and different roles get different permissions. Designing that structure early prevents a painful retrofit later.
For business customers, single sign-on and centralized provisioning are often deal requirements. We build so those enterprise capabilities can be added as real customers ask for them, without tearing up the foundation.
- Team and organization accounts with invitations and seat management
- Role-based access control (owner, admin, member, read-only, and custom roles)
- Permission checks enforced on the server, not just hidden in the UI
- SSO via SAML/OIDC readiness for enterprise identity providers
- SCIM-style provisioning and deprovisioning for larger accounts
- An audit trail of logins and permission changes

Frequently asked questions
Should we build authentication ourselves or use a provider?
For most teams, building on a proven identity provider or well-established library is the safer, faster choice. Authentication has many security-critical edge cases, and rolling your own crypto or session handling is a common source of serious vulnerabilities. We use trusted infrastructure and focus our effort on integrating it cleanly with your product.
Do we need SSO right away?
Usually not. Most products launch with email and social login and add SSO when a business customer requires it. We design the user and permission model so SSO and enterprise provisioning are additions later, not a rebuild. Adding them prematurely spends effort before there's a customer paying for it.
How do you keep permissions from being bypassed?
Every permission check is enforced on the server, where the user can't tamper with it. Hiding a button in the UI is not security. We treat the backend as the authority on who can do what, and keep an audit trail of sensitive actions so you can see what happened.
