Frequently Asked Questions
NIST recommends a minimum of 8 characters, but security experts suggest 16+ for important accounts. Length matters more than complexity — a 20-character random password is far stronger than a 10-character one with symbols.
Yes. Passwords are generated using the Web Crypto API (window.crypto.getRandomValues), which provides cryptographically secure randomness. Passwords are never sent to any server — they are generated and displayed entirely in your browser.
Absolutely. Memorising unique, random passwords for every account is not realistic. A reputable password manager (such as Bitwarden, 1Password, or KeePass) stores and fills passwords securely, so you only need to remember one strong master password.
A strong password is long, random, and unique per account. Length is the most important factor — each additional character multiplies the number of possible combinations exponentially. Avoid dictionary words, predictable patterns, and reusing passwords across accounts.
Yes. This generator is suitable for any password — account logins, Wi-Fi keys, database passwords, API keys, and more. For Wi-Fi, 20+ characters with all character types is recommended.
