Password Generator – Create Strong Random Passwords

At minimum, 12–16 characters for standard accounts. For financial and critical accounts, use 20+ characters or a multi-word passphrase. Length is more important than complexity — a 20-character lowercase password has more entropy than a 10-character password with symbols.

Generated passwords should be stored in a reputable password manager (Bitwarden, 1Password, KeePass), not in a text file, browser-only storage, or written on sticky notes. Password managers encrypt your vault — even if the service is compromised, your passwords remain secure.

Short length, common words or patterns, and reuse across sites. Modern GPUs can test billions of passwords per second. An 8-character all-lowercase password has only 208 billion combinations — feasible to crack in hours. A 16-character random password has 10^31 combinations — infeasible for decades.

Yes — passphrases (4+ random words like "correct-horse-battery-staple") are highly secure and more memorable. A 4-word passphrase from a large wordlist has 50+ bits of entropy. The key is that the words must be randomly selected, not a meaningful phrase you'd naturally say.

Current NIST guidance (2020) says routine password expiration is counterproductive — it leads to predictable modifications ("password1" → "password2"). Change passwords only when there's evidence of compromise. Strong, unique passwords that haven't been breached don't need rotation.
