How to Use
Create strong, unique passwords in seconds:
- Adjust the Length slider or type a number (4–128 characters).
- Toggle the character types you want: uppercase, lowercase, numbers, and symbols.
- Enable Exclude ambiguous to remove confusing characters like l, 1, I, O, and 0.
- Click Generate for a new password, or Generate 5 for multiple passwords at once.
- Click the clipboard icon next to any password to copy it.
Strength Meter
- Weak — Very short or too few character types. Easy to crack.
- Fair — Below average. Consider increasing length or adding more character types.
- Good — Solid password for most uses.
- Strong — Excellent. Very difficult to crack with brute force.
Tips
- Use at least 16 characters for important accounts.
- Include all four character types (uppercase, lowercase, numbers, symbols) for maximum strength.
- Never reuse passwords across different accounts.
- Use the Exclude ambiguous option when you might need to read or type the password manually.
- Use Generate 5 to quickly create passwords for multiple accounts.
- Password history is session-only and clears when you close the page.
Frequently Asked Questions
How secure are the generated passwords?
Passwords are generated using the Web Crypto API (crypto.getRandomValues), which provides cryptographically secure randomness — the same standard used in security software.
What password length should I use?
Use at least 16 characters for important accounts. Longer passwords with all four character types (uppercase, lowercase, numbers, symbols) are exponentially harder to crack.
Are generated passwords stored anywhere?
No. Passwords are generated entirely in your browser and are never sent to any server. Password history is session-only and clears when you close the page.
What do the strength ratings mean?
Weak means the password is very short or uses too few character types. Fair is below average. Good is solid for most uses. Strong means it is very difficult to crack with brute force.
Can I generate multiple passwords at once?
Yes. Click Generate 5 to create five passwords at once with your current settings, so you can pick the one you like best.
About
Strong, unique passwords are your first line of defense against unauthorized access. A password generator removes the guesswork by creating truly random combinations that are much harder to crack than human-created passwords.
This tool generates passwords entirely in your browser using the Web Crypto API (crypto.getRandomValues) for cryptographically secure randomness. No passwords are sent to any server or stored anywhere beyond your current browser session.
From the build: we deliberately avoided Math.random(). It's fine for a coin flip, but it's not cryptographically secure — the sequence is predictable if you know enough about its state, and a generated password should be genuinely unguessable. The Web Crypto API ships in every modern browser and gives the same quality of randomness as production security software. The "exclude ambiguous" option exists because of a recurring piece of feedback: people kept asking why they couldn't tell a lowercase L from a 1, or a capital O from a 0, when typing a generated password into another device. It's a one-line filter that solves a real annoyance.
