Authentication & Authorization
Authentication proves who a user is; authorization decides what they can do. Get either wrong and everything else is moot. Yet these are exactly the areas teams most often hand-roll insecurely — weak sessions, client-trusted roles, passwords stored badly.
We build identity the right way: secure session handling, strong credential storage, MFA-ready flows, and authorization that is always decided on the server, never trusted from the client.
Problems we solve
Roles trusted from the client
If the browser tells the server what the user is allowed to do, the check is worthless. Authorization must be server-authoritative.
Weak session and credential handling
Long-lived tokens, weak password hashing, and no rotation turn one leak into a persistent compromise.
No separation between user types
Sharing one identity system across staff and customers without separate trust domains means one breach crosses boundaries it should not.
How we approach it
Server-authoritative authorization
Every permission is resolved on the server from the source of truth, so a role forged in a token or request body is ignored — and sensitive denials are audited.
Secure sessions and credentials
HttpOnly cookies or short-lived tokens, strong password hashing, and MFA-ready flows, with separate signing secrets for separate trust domains.
Least privilege and safe defaults
New users get the least access needed; deactivation takes effect immediately; and the system fails closed when identity cannot be verified.

Frequently asked questions
Do you support MFA and SSO?
Yes — we build MFA-ready flows and integrate SSO / enterprise identity; see our SSO & Enterprise Identity service for federated login with providers like Okta, Azure AD, and Google Workspace.
How do you stop users escalating their own permissions?
Authorization is always resolved server-side from the source of truth, so a role claimed in a token or request body is ignored, and sensitive denials are logged.
Where are passwords stored?
Never in plain text — we use strong, modern hashing (e.g. Argon2/bcrypt) and never store or log credentials.
