How to convert password generator
Pick a length
Choose 16 to 48 characters — 16 is fine for most accounts, 32+ for admin or encryption keys.
Generate
The password is created with your browser own cryptographic random generator, locally.
Copy and store
Copy it straight into your password manager — it never touches a server, so it cannot be recovered if lost.
Frequently asked questions
How random is it?
Every character comes from crypto.getRandomValues with rejection sampling, so all characters are equally likely — no modulo bias.
Are the passwords sent anywhere?
No. Generation happens entirely in your browser tab; nothing is logged or transmitted.
Why do some characters look missing?
The character set intentionally skips look-alikes (l, I, 1, O, 0) so passwords stay easy to read aloud and type.
Does every character class appear?
Yes — lowercase, uppercase, digits and symbols are each guaranteed at least once, then the rest is shuffled.
