Two things: length and randomness. Every extra character multiplies the number of possibilities an attacker must try, and truly random characters defeat the dictionary and pattern attacks that crack human-invented passwords in seconds. A random 16-character password using all character sets has around 100 bits of entropy — far beyond what any realistic brute-force attack can search.
This generator uses your browser's cryptographically secure random number generator (the same Web Crypto API used for TLS), with unbiased sampling and a guarantee that every selected character set appears at least once. Generation happens entirely on your device: no network request carries your password, and nothing is logged or stored.
The best practice today: generate a unique random password for every account, store them in a password manager, and enable two-factor authentication on anything important.
On this one, yes — the password is generated by your own browser using the Web Crypto API and never transmitted. You can disconnect from the internet, generate a password, and close the tab; no server ever sees it.
16 characters is a solid modern default for random passwords; use 20+ for critical accounts like email and banking. Anything under 12 random characters is increasingly crackable with modern GPU hardware.
It measures how many guesses an attacker would need — each bit doubles the search space. Roughly: under 45 bits is weak, 65+ is strong for online accounts, and 90+ resists even offline attacks against stolen password databases.
Characters like I, l, 1, O, and 0 are easily confused when a password must be read or typed by hand — on a TV screen, a Wi-Fi card, or over the phone. Excluding them slightly reduces entropy, so add a couple of characters of length to compensate.
Yes. The point of random passwords is that they're impossible to remember — a password manager stores a unique one per site and fills it for you, which also protects you from phishing lookalike domains.
