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

- Highest security
- Device-bound
Start Migration
Begin with optional passkey registration, then gradually encourage adoption before enforcing passwordless.
