›Are these passwords truly random?
Yes — generated using crypto.getRandomValues(), the browser's cryptographically secure RNG.
›Are the passwords logged anywhere?
Never. Generation happens locally and nothing is sent over the network.
›How long should a password be?
Minimum 12 characters with mixed case, numbers and symbols. 16+ is recommended for sensitive accounts.
›Should I use a password manager instead?
Yes — generators like this are great for one-off passwords, but a password manager (1Password, Bitwarden, etc.) is the right long-term solution.
›Can I exclude ambiguous characters?
Yes — toggle 'no ambiguous' to drop characters like 0/O, 1/l/I that are hard to tell apart visually.
›Is the generator free?
Yes — fully free, no signup, no ads.
