How to Use the Password Generator
Set length (8–64), choose character types (uppercase, lowercase, numbers, symbols), optionally exclude ambiguous characters (l, 1, O, 0, I). Click generate or press refresh. Copy with one click.
Password Generator Formula
Entropy = log2(charset_size^length); Strength = base(length) + 10 per char type − 10 if <12 charsExample Calculation
Length 16, all character types:
Charset size ≈ 95; Entropy = log2(95^16) ≈ 105 bits
Very Strong password; 105 bits entropy

100% client-side using window.crypto.getRandomValues() — the most secure source of randomness in browsers. Your password is never sent to any server. You can verify by disconnecting your internet and the tool still works.
