Why Passwordless?

Passwords are the weakest link in security. Passkeys use public-key cryptography with biometric unlock - phishing-resistant by design.

Phishing-Resistant

Passkeys are bound to the origin. There's no password to steal, no credential to phish. Attackers cannot replay authentication.

Authentication Flow

Phase 1

User Request

Initiates login

Phase 2

Biometric

Face ID/Touch ID

Phase 3

Key Signs

Cryptographic signature

Phase 4

Verified

Server validates

Passwords vs Passkeys

Passwords (Old)

Phishable
Reused across sites
Stored in databases
Weak entropy
User friction

Passkeys (New)

Phishing-resistant
Unique per site
Never leaves device
Strong cryptography
Seamless UX

Implementation

Platform Authenticators

  • Windows Hello
  • Apple Face ID/Touch ID
  • Android biometrics
  • Synced across devices

Security Keys

  • YubiKey
  • Titan Security Key
  • Highest security
  • Device-bound

Start Migration

Begin with optional passkey registration, then gradually encourage adoption before enforcing passwordless.
