About Password Generator
Generate strong, random passwords in seconds. Pick a length from 6 to 64 and choose which character types to include — uppercase, lowercase, numbers, and symbols — then optionally exclude look-alike characters like l, 1, I, O, and 0. Every password uses your browser's cryptographic random generator and is guaranteed to include at least one character from each set you select, with a live strength rating.
This tool is completely free with no sign-up, no limits, and no ads getting in the way. It runs entirely in your browser, so the passwords it creates never touch a server. Copy the result with one click or hit regenerate until you get one you like.
Frequently asked questions
- Is this password generator free to use?
- Yes, it is completely free with no account, no sign-up, and no usage limits. Generate as many passwords as you want, as often as you like.
- Is my data uploaded or stored anywhere?
- No. Every password is generated locally in your browser using the crypto.getRandomValues API. Nothing you generate is sent to a server, logged, or stored — close the tab and it is gone.
- How random and secure are the passwords?
- They use your browser's built-in cryptographically secure random number generator (crypto.getRandomValues) with rejection sampling to avoid bias, which is far stronger than typical Math.random() based tools. Each password is also guaranteed to include at least one character from every set you enable.
- What does 'exclude ambiguous characters' do?
- It removes characters that are easy to confuse when reading or typing — lowercase l, the number 1, uppercase I, uppercase O, and the number 0. This is handy when you need to read a password aloud or copy it by hand.
- What length should my password be?
- Longer is stronger. For most accounts 16 or more characters with a mix of types is a solid choice, and the built-in strength meter updates live as you adjust the length and character sets. You can go up to 64 characters for maximum security.
- Can I use this on my phone?
- Yes. The tool works in any modern mobile or desktop browser, and the one-click Copy button lets you paste the password straight into a signup form or password manager.
