Why use a strong password?
A strong password makes guessing and automated attacks far more expensive. Length, unpredictability and uniqueness matter more than clever substitutions. Use a different password for every account and store them in a trusted password manager.
Random password or passphrase?
Random characters maximize variety in a compact string. A multi-word passphrase is often easier to type and remember while remaining strong when it contains enough randomly chosen words.
How is it generated?
This tool uses your browser’s crypto.getRandomValues source rather than predictable pseudo-random values. The displayed entropy is an estimate based on selected character sets or word count; it is a guide, not a guarantee.
