Passkeys vs Passwords – Which Is the Better Authentication Choice?

Passkeys, built on the FIDO2/WebAuthn standards, represent a modern authentication method addressing the security vulnerabilities and usability challenges associated with traditional passwords. Unlike knowledge-based passwords, passkeys utilize a possession-based model involving a device-bound private-public key pair, enhancing security against phishing, credential stuffing, brute-force attacks, and database leaks. Users authenticate using biometrics or a device PIN, resulting in a more intuitive and seamless user experience without the need to remember or reset passwords. Cross-device synchronization is facilitated by ecosystems like Apple iCloud Keychain and Google Password Manager, while platforms like SuperTokens offer tools for implementing WebAuthn-based passwordless login, allowing for flexible authentication flows that can incorporate passkeys alongside traditional methods. Although the transition to passkeys is gradual due to device compatibility and user education challenges, industry leaders such as Apple, Google, and Microsoft are driving the shift towards this secure, efficient authentication approach, which is becoming increasingly supported across major platforms and browsers.
