given answer is correct . as:
The correct answer is: 1. Passwordless authentication: high security & convenient ✅
Here’s why it earns both labels:
🔐 High Security
- It eliminates the vulnerabilities of passwords — no more phishing, brute-force attacks, or credential stuffing.
- Uses strong methods like biometrics, FIDO2 passkeys, hardware tokens, and public key cryptography that are extremely difficult to spoof or steal.
📱 Convenient
- No need to remember or reset passwords — users log in with a fingerprint, face scan, or a tap on a trusted device.
- Works seamlessly across devices
No incorrect, Passwordless is conventient with high-security while MFA supports security but overall convenience decreases, and password authentication is low on security.
