Why Most Password Generators Are Not as Private as They Claim to Be

Password generators are one of those tools everyone assumes are trustworthy by default, since the whole point is randomness and security. In practice a lot of them are not. Some log what you generate server side. Some run ad networks that fingerprint you across sites. A surprising number generate the password on a server and send it to your browser, which means the "random" string already left your machine before you even saw it, defeating the entire purpose of generating it randomly in the first place.

We built the Password Generator at BetterUtils to close that gap entirely. Everything runs client side, in your browser, using the Web Crypto API for cryptographically secure random number generation. Nothing you generate is transmitted, logged, or stored anywhere, including on our end. You can turn off your internet connection after the page loads and the tool still works fine, which is a simple way to confirm nothing is being sent out.

Why entropy matters more than a clever password

Every character type you add to a password multiplies the number of combinations an attacker has to try. A 16 character password using uppercase, lowercase, numbers, and symbols would take a well resourced attacker with modern hardware an impractically long time to brute force. Something like "password123" can fall to a basic dictionary attack in under a second. Length matters more than most people expect too. Adding a single extra character increases the search space exponentially, not linearly, so going from 12 to 16 characters is a much bigger jump in security than it sounds.

What the tool actually gives you

A length slider from 8 to 64 characters, toggles for uppercase, lowercase, numbers, and symbols, a live strength indicator that updates as you adjust the settings, and a one click copy button. No account, no email capture, no daily generation limit. You can try it directly at betterutils.com/tools/password-generator.

A few practical habits worth pairing with it

Generate a unique password for every account instead of reusing one. Store what you generate in an actual password manager rather than a plain text file or a sticky note. Turn on two factor authentication anywhere it is offered, since a strong password alone only protects against guessing attacks, not every attack vector.

If you build software and need API keys or secrets instead of login passwords, BetterUtils also has a Secret Key Generator built the same way: everything local, nothing stored, nothing sent anywhere.
