Password Generator
Generate strong random passwords with custom length and character sets — generated entirely in your browser.
Frequently Asked Questions
How does this password generator create random passwords?
It uses the browser's Web Crypto API (crypto.getRandomValues), a cryptographically secure source of randomness. You choose the length and which character sets to include — uppercase, lowercase, numbers and symbols.
What makes a strong password?
Length is the most important factor: aim for at least 16 characters. Mixing uppercase, lowercase, numbers and symbols increases the number of possible combinations, making the password far harder to guess or brute-force.
Are the generated passwords stored anywhere?
No. Passwords are generated locally in your browser and are never transmitted or saved. Once you close the tab, they are gone, so copy any password you want to keep into a password manager.
Can I generate passphrases or exclude similar characters?
You can adjust length and character sets to avoid easily confused characters such as l, 1, O and 0. For accounts you type often, a long passphrase of several random words can be both strong and memorable.
