How to use Password Generator
- Pick a length — 16 characters is a good baseline; 20+ is recommended for anything sensitive.
- Toggle which character sets to include: lowercase, uppercase, digits, and symbols.
- Turn on 'Avoid look-alikes' if the password will be typed manually (removes 0/O/I/1/l).
- Click Generate for a fresh password. Copy it, paste it into your password manager, and never rely on remembering it.
Common use cases
- New account signup. Generate a unique 20-character password per site. Store in a password manager — reusing passwords is the #1 cause of account takeovers.
- API keys and dev secrets. Use 32+ characters with all sets enabled. Copy directly into .env files (never commit .env).
- Temporary shared password. Enable 'Avoid look-alikes' and use 12–14 characters when you need to dictate a password over the phone or paste into chat.
- PIN or numeric code. Enable only 'digits' to generate secure numeric PINs of any length — much stronger than birthdays or repeated digits.
Tips
- Length beats complexity. A 20-char password with only lowercase is stronger than a 10-char password with all sets.
- Never reuse a generated password across sites. Even one breach compromises every account with the same password.
- The generator uses `crypto.getRandomValues()` — the same cryptographic randomness used by browsers for TLS keys.
- Password managers (Bitwarden, 1Password, KeePass) can auto-generate and auto-fill so you never see or memorize your passwords.
Troubleshooting
- The site rejects my password.
- Some sites impose length caps (16 or 20 chars) or ban specific symbols. Shorten the password or turn off 'Symbols' if a specific site is being finicky.
- I need to memorize a password.
- Consider a 4-word passphrase instead (e.g., correct-horse-battery-staple). Diceware-style passphrases are memorable and cryptographically strong.
