Even with the best encryption, one simple weakness can still expose your business: bad passwords. In the quantum age, that vulnerability becomes even more dangerous.
Quantum algorithms like Grover’s algorithm can dramatically reduce the time it takes to brute-force passwords and encryption keys. That means short, predictable, or reused passwords could be cracked much faster once quantum computing matures.
The solution? Focus on length, not just complexity. Use passphrases of 16+ characters, combine words that are easy to remember but hard to guess, and avoid predictable substitutions. Complement this with multi-factor authentication (MFA) or, even better, passwordless authentication using biometrics or hardware tokens.
Also, monitor password health continuously. Tools like password managers and enterprise access systems can enforce rotation and alert you to breaches.
In short, the quantum age demands smarter password hygiene. Even the strongest encryption can’t protect you if your front door — your passwords — stays unlocked.
