Our Users’ Favorite Features
-
The “magical” Clef Wave: login securely without passwords, and enjoy two-factor protection without one-time codes.
-
Convenience: use your smartphone for strong authentication instead of a “third device” such as a USB drive or extra security key.
-
Single sign on/off: Sync with the Clef Wave once, then enjoy one-click sign ins for all subsequent sites. Also, you are automatically logged out when you’re done working.
Security Features
-
Strong authentication: Clef replaces passwords with highly secure two-factor logins using the tried-and-true RSA public-key cryptosystem.
- Clef stores your encrypted private key on your phone rather than in a central database. Thus even in the unlikely event of a catastrophic security breach on Clef’s servers, your login credentials remain secure on your phone.
- Every Clef login requires two identification factors: your phone and a fingerprint or PIN. So even if your phone is lost or stolen, you’ll be safe.
-
Comprehensive protection: Clef disables passwords for all three WordPress authentication vectors: Dashboard access, API access, and automatic password resets via email. Thus it protects against the full spectrum of password-based attacks:
- brute-force and botnet login attacks
- weak, reused, and recycled passwords
- sending login credentials via an insecure (non-ssl) connection
- password phishing attempts
- account takeovers via email account breaches
