About this tool
Choose length and which character classes to include (lowercase, uppercase, digits, symbols, exclude lookalikes). Passwords come from window.crypto.getRandomValues so they're cryptographically random, never sent anywhere, and never reused.
FAQs
How long should my password be?
16 characters with a mix of classes is fine for most accounts. 24+ for password manager master passwords or anything storing money.
Is the randomness safe?
Yes - we use the browser's Web Crypto getRandomValues, which draws from the OS CSPRNG. Same source used by JWT libraries and Node crypto.
What are 'lookalike' characters?
Characters like 0/O/o, 1/l/I, 5/S that look similar in some fonts. Excluding them helps when reading the password aloud.
