Passwords are the weakest link in digital security. Passkeys and biometric authentication are eliminating them — here's how to implement the future of authentication.
Passwords are the most widely exploited vulnerability in digital security — 81% of data breaches involve compromised credentials. The solution isn't stronger passwords; it's eliminating passwords entirely. Passkeys — the FIDO2/WebAuthn standard supported by Apple, Google, and Microsoft — are the authenticated future, and our web development company India team is implementing them in new client projects as the default authentication approach.
How Passkeys Work
Passkeys use public-key cryptography to authenticate users without transmitting secrets over the network. When a user creates a passkey, a public/private key pair is generated — the private key stays on the user's device (iPhone, Android, Windows), the public key is registered with the website. Authentication is a cryptographic challenge-response using Face ID, Touch ID, or PIN — no password, no phishing, no credential stuffing. The user experience is: tap or glance, you're in.
Implementation for Indian Web Apps
WebAuthn implementation in a React application uses the Passkey library or @simplewebauthn packages, with server-side handling via Supabase Auth (native passkey support in 2024) or a custom implementation against the WebAuthn spec. For Indian businesses where users operate on a mix of Android (Passkey support via Google Password Manager) and iOS (Passkey support via iCloud Keychain), both paths are now seamless. Our custom website development team includes passkey implementation in every new authentication system as the primary login method.
