Passkeys have been proven to be an effective passwordless authentication method replacing traditional authentication mechanisms.
First, here're 3 quick facts about passwords:
Comparing Passkeys to Passwords based on attack surface.
| Attack Vector | Description | Passkeys Vulnerable? |
|---|---|---|
| Credential Stuffing | Automated login attempts using breached username/password pairs | ❌ Immune no shared secret |
| Phishing | Fake login pages harvesting credentials | ❌ Immune origin-bound |
| AiTM Proxy | Real-time proxy (Evilginx) stealing session tokens | ❌ Immune challenge is origin-specific |
| Brute Force | Systematic password guessing | ❌ Immune no password to guess |
| Password Spraying | Common passwords against many accounts | ❌ Immune no password exists |
| SIM Swap (SMS OTP) | Hijacking phone number for OTP interception | ❌ Immune no OTP channel |
| Push Fatigue | Spamming MFA push notifications until user accepts | ❌ Immune no push to spam |
| Keylogging | Recording keystrokes to capture passwords | ❌ Immune biometric/PIN on secure hardware |
| Server Breach | Stealing password hashes from database | ❌ Immune server stores only public keys |
By implementing Passkeys for authentication, we can:
