FAQ
What is a passkey and how is it different from a password?
A passkey is a modern, passwordless login method based on WebAuthn standards. It uses device-based authentication such as biometrics or security keys instead of passwords, making it more secure and easier for users.
Will passkeys work on all browsers and devices?
Passkeys are supported on all modern browsers and operating systems. I ensure compatibility for supported environments and handle proper error and fallback flows where passkeys are not available.
Can passkeys be added to an existing login system?
Yes. Passkeys can be integrated alongside your existing authentication system. Users can continue using their current login method and optionally create passkeys for passwordless access.
Do you support multiple passkeys per user?
Yes. Users can create and manage multiple passkeys, allowing login from multiple devices securely.
Which backend technologies do you support?
I support all major backend technologies including Node js, Express, Nest js, Django, Laravel, Spring Boot, Ruby on Rails, and Go based backends.
Is passkey authentication secure for production use?
Yes. Passkeys follow industry-standard cryptography and are resistant to phishing and credential theft. I implement them using security best practices suitable for production environments.
Will you provide documentation after integration?
Yes. I provide clear documentation explaining how passkeys are implemented and how they can be managed or extended in the future.
Do you need access to my production system?
No. Development or staging access is sufficient. I recommend testing passkey integration thoroughly before deploying to production.
