About Password Generator
The Password Generator builds passwords from your browser's cryptographic random generator, picking each character without bias and making sure every set you choose appears at least once. The strength meter estimates entropy in bits from the length and the size of the character pool. It runs entirely in your browser, with nothing sent anywhere or saved.
FAQs
How long should a password be?
16 characters with all four sets is very strong for most accounts. Use 20 or more for a password manager's master password.
Is it truly random?
Yes. It uses crypto.getRandomValues, the same source browsers use for encryption, with rejection sampling so no character is favoured.
Why exclude look-alikes?
Characters like O and 0 or I, l and 1 are easy to mix up when you read or type a password by hand.
