How to use Password Generator
1
Set the desired password length using the slider (8 to 64 characters). The default is 16.
2
Choose which character types to include: uppercase, lowercase, numbers, and/or symbols.
3
Optionally, check "Exclude ambiguous characters" to remove characters like 0, O, o, 1, l, I.
4
Click "Generate Password" to create your password. Use Copy, Regenerate, or Clear as needed.
How it works
This password generator uses the Web Crypto API (crypto.getRandomValues()) to produce cryptographically secure random numbers. This is the same randomness source used by browsers for TLS/SSL connections.
- Cryptographic randomness: Unlike
Math.random(), which is pseudo-random and predictable,crypto.getRandomValues()draws from the operating system’s cryptographically secure random number generator (CSPRNG). - No server communication: The entire generation process happens in your browser. The password is never transmitted, stored, or logged anywhere.
- Strength evaluation: The strength bar checks password length and the variety of character types used. Longer passwords with more character types are exponentially harder to crack via brute force.
- Ambiguous character exclusion: Optionally removes characters that look similar in many fonts (0/O/o, 1/l/I) to reduce errors when reading or typing the password.

Frequently Asked Questions
Is this password generator safe to use?
Yes. It uses crypto.getRandomValues(), which is the gold standard for client-side cryptographic randomness. The password is generated entirely in your browser and is never sent to any server.
Are the passwords stored anywhere?
No. Passwords are generated on-the-fly and displayed only on your screen. They are not stored in cookies, local storage, or sent to any server. Once you navigate away or clear the display, the password is gone.
What makes a password strong?
A strong password is long (16+ characters) and uses a mix of character types (uppercase, lowercase, numbers, and symbols). The strength indicator shows four levels: Weak, Medium, Strong, and Very Strong based on length and character diversity.
How long should my password be?
We recommend at least 16 characters for strong security. For high-value accounts (banking, email), consider 20-32 characters. The longer the password, the more resistant it is to brute-force attacks.
What does "Exclude ambiguous characters" mean?
Some characters look very similar in many fonts, such as the letter "O" and the number "0", or "l" (lowercase L) and "I" (uppercase i). Enabling this option removes these characters so your password is easier to read and type correctly.
Can I use this for generating passwords for multiple accounts?
Absolutely. Each click of "Generate" or "Regenerate" creates a brand new, unique password. We recommend generating a different password for every account and using a password manager to store them securely.
