We build authentication that doesn't get your users phished — NextAuth, OAuth/SAML SSO for enterprise, passkeys for passwordless, and zero-trust session management. MFA, device pairing, step-up auth and audit logs are designed in. You get a system your CISO can defend.
What is auth and identity? Auth and identity is the engineering of secure login, session and access systems for software products — covering passwords, MFA, SSO and passkeys. ClickTake delivers auth and identity services for UK SaaS brands, using Auth0, Clerk, NextAuth and Postgres to ship audited, breach-resistant identity.
Every engagement ships with these deliverables baked in — not bolted on later.
Auth.js v5 with database or JWT sessions — adapter chosen against your scaling needs, not by default.
SAML and OIDC SSO for enterprise customers — the kind that closes a 6-figure deal — with IdP-specific metadata handling.
WebAuthn passkeys deployed alongside passwords so users can opt in — and we measure how fast adoption actually happens.
Short-lived rotating tokens, device binding and server-side session revocation that survives a stolen refresh token.
Risk-based step-up auth for sensitive actions (billing, exports, admin) — not a blanket MFA prompt on every login.
Every login, MFA challenge, SSO link and admin action logged with user, IP, device and timestamp — exportable for SOC 2.
The production stack we ship for auth & identity.
Senior engineers (8+ yrs avg) own every engagement. CI/CD from day one, observability baked in, and a p99 120ms performance budget enforced in CI.
A tailored 4-step process for auth & identity.
We map your user types, devices, risk levels and required auth factors — documented before any code is written.
We choose auth providers, session strategy and token lifetimes against your threat model, not against convenience.
We implement auth, MFA, SSO and audit logging, with rate limiting, account lockout and credential-stuffing protections.
We run an OWASP-aligned review, ship to production behind feature flags, and monitor for anomalies over the first 30 days.
