 +===== Quantum-Resilient Password Lengths ===== 
 +As of May 2025 
 +^Password Use Case^Recommended Length (Post-Quantum)^Notes^ 
 +|Standard login password (hashed with bcrypt/scrypt/Argon2)|16+ characters|Include upper/lowercase, numbers, symbols. Use a passphrase (e.g., "CorrectHorseBatteryStaple").| 
 +|High-security systems (admin, financial, sensitive data)|20–24+ characters|Use passphrases or random strings from a password manager.| 
 +|Encryption passphrases (e.g., PGP, file encryption)|32+ characters|Quantum attacks may eventually brute-force shorter keys; longer passwords help mitigate risk.| 
 +|Wi-Fi passwords (WPA3)|16–24 characters|Use maximum supported length to reduce offline cracking potential.|
