Why Password Entropy Matters
Password security is governed by entropy measured in bits of information. A 16-character password combining letters, numbers, and symbols has over 90 bits of cryptographic entropy, requiring modern supercomputers quadrillions of years to crack via brute-force dictionary attacks.
Frequently Asked Questions
Are these passwords stored or transmitted?
Never. Generation relies exclusively on window.crypto.getRandomValues, executing locally inside your web browser. No network requests are made.
What length is recommended?
Cybersecurity agencies (such as CISA and NIST) recommend a minimum of 16 characters for critical accounts such as banking, email, and password managers.
