# What are passkey security benefits over passwordless auth?

## Passkey Security Benefits Over Passwordless Authentication

Passkeys provide a **higher level of security** compared to traditional passwordless
authentication methods. While passwordless solutions
[eliminate passwords](https://www.corbado.com/faq/boost-passkey-enrollment-reduce-password-otp), they often still
rely on shared secrets (e.g., SMS OTPs, email magic links) that remain **vulnerable to
phishing and interception**. Passkeys, on the other hand, use **asymmetric cryptography**,
making them both **passwordless and phishing-resistant**.

### Key Security Advantages of Passkeys

1. **Phishing Resistance**
    - Traditional passwordless methods (SMS OTPs, magic links) can be intercepted if a
      user is tricked into entering them on a fake site.
    - Passkeys prevent [phishing](https://www.corbado.com/glossary/phishing) by binding authentication to a
      legitimate domain. Even if an attacker tries to redirect a user, the passkey won’t
      complete authentication.

2. **Elimination of Shared Secrets**
    - Many passwordless methods still involve a **reusable secret** (e.g., OTPs, email
      links).
    - Passkeys **do not transmit secrets** over the network—only a cryptographic proof is
      exchanged, making them immune to replay attacks.

3. **Protection Against Credential Theft**
    - Passwordless systems using TOTP (Time-Based One-Time Passwords) or push
      notifications can still be stolen via social engineering.
    - Passkeys store the **private key securely on the user’s device**, preventing
      attackers from gaining control remotely.

4. **No SIM-Swap Vulnerability**
    - SMS-based [passwordless authentication](https://www.corbado.com/glossary/passwordless-authentication) is
      **vulnerable to SIM-swapping attacks**.
    - Passkeys do not rely on phone numbers, eliminating this risk.

5. **Stronger Device Security**
    - Passkeys leverage **biometrics (Face ID, Touch ID, Windows Hello)** or a **secure
      PIN**, providing a seamless and secure login experience.
    - Traditional [passwordless authentication](https://www.corbado.com/glossary/passwordless-authentication) may
      still require a fallback password, reducing its security.

### Final Verdict

While [passwordless authentication](https://www.corbado.com/glossary/passwordless-authentication) reduces
friction, **not all passwordless methods are phishing-resistant**. **Passkeys provide both
passwordless convenience and phishing resistance, making them the superior choice for
enterprises**. By adopting passkeys, organizations enhance security while **eliminating
password-related risks altogether**.
