Passkeys vs Passwords: Should You Switch?

TL;DR

  • Passkeys are a modern, cryptographic replacement for passwords that remove the need to type or remember passwords.
  • Passkeys are generally more secure against phishing and credential leaks, but require device support and a reliable recovery plan.
  • Best for users who use passwordless-enabled services and have smartphones or platform accounts for backup.

What are passkeys

  • Passkeys use public key cryptography. The server stores a public key, the device keeps a private key.
  • Authentication is done via biometric or PIN unlock on your device, not by sending a password.
  • They are standardized by FIDO and W3C, and aim to be cross-platform via platform authenticators and roaming authenticators.

Security differences

  • Passwords: vulnerable to phishing, reuse attacks, and server breaches where hashes are stolen.
  • Passkeys: resistant to phishing because authentication requires the correct origin and the private key never leaves the device.
  • Passkeys reduce attack surface by removing shared secrets stored on servers.

Usability and sign-in flow

  • Password flow: user types email and password, may use 2FA codes or authenticator apps for extra security.
  • Passkey flow: user chooses 'continue with passkey', unlocks device biometric or PIN, and signs in automatically.
  • Passkeys simplify sign-in, speed up onboarding, and reduce login friction on mobile and desktop when supported.

Device and platform support

  • Most major platforms and browsers now support passkeys, including Android, iOS, Windows, macOS, Chrome, Edge, Safari, and Firefox.
  • Limitations exist on older devices, some browser versions, and services that have not implemented passkey login.
  • Cross-device sign-in typically uses platform account sync or QR code pairing to transfer credentials securely.

Account recovery and backup

  • Passwords rely on reset-by-email flows which are widely understood but can be abused via SIM swap or email compromise.
  • Passkeys require a recovery method: platform account sync, export/import tools, or a secondary device set up as a backup.
  • Before switching, confirm the services you use offer robust recovery options to avoid lockout.

When to switch

  • Switch when your primary services support passkeys and you have at least one reliable device or account-based backup.
  • Keep a transition plan: enable passkeys on key accounts first, verify recovery, then remove old passwords if desired.
  • For shared or public accounts, passwords or shared credential managers may still be necessary in some cases.

Migration checklist

  • Verify passkey support on your email, cloud storage, banking, and social accounts.
  • Enable platform sync or export your passkeys where supported and set up an extra trusted device.
  • Keep a secure password manager as fallback during transition and update account recovery contact methods.

Bottom line

Passkeys offer a stronger, easier to use authentication method that greatly reduces phishing and credential theft risk. They are ready for mainstream use but require attention to device support and recovery options. If your core services support passkeys and you have a reliable backup plan, start switching now for better security and smoother sign-ins.
