Password Generator

A strong password is long (at least 14–16 characters) and includes a mix of uppercase letters, lowercase letters, numbers, and special symbols.

No. All passwords are generated locally in your browser using secure client-side cryptographic random numbers (Web Crypto API).

Cybersecurity experts recommend using passwords at least 16 characters in length for sensitive online accounts.

Password entropy is a mathematical measure of a password's unpredictability, calculated in bits. Higher entropy means a password requires exponentially more computational attempts to crack via brute force.

NIST Special Publication 800-63B recommends prioritizing password length over arbitrary character composition rules and avoiding mandatory periodic password expiration unless a breach is suspected.

A passphrase combines multiple random words (e.g. 'correct-horse-battery-staple'). Passphrases offer high entropy while remaining easy for humans to memorize without complex symbol substitutions.

Dedicated, audited password managers (like 1Password, Bitwarden, or KeePass) offer stronger zero-knowledge end-to-end encryption than basic built-in browser autofill storage.
