FAQ
Custom Login, answered.
Straight answers to the things people ask us most. Anything else? Just reach out.
Ask us anything Should we build custom authentication or use a provider like Auth0?
Usually both. We rely on proven identity providers for the security-critical core and build a fully custom, branded experience on top, so you get enterprise-grade security without the generic look.
What are passkeys and why do they matter?
Passkeys replace passwords with device-based cryptographic credentials such as Face ID, fingerprint or Windows Hello. They are phishing-resistant, faster for users and eliminate password resets.
Can you add SSO to our existing application?
Yes. We regularly add SAML and OIDC single sign-on to existing applications so you can close enterprise deals that require it.
How do you handle security testing?
Every project includes threat modelling, secure code review and automated scanning, and we coordinate third-party penetration testing when required.
Can users from different companies have separate access?
Yes. We build multi-tenant organization models where each customer manages its own users, roles and SSO connection.
