Why a strong password matters

Most account breaches don't come from some sophisticated technical exploit. They come from a password that was too weak or already known to attackers. A short password based on a dictionary word or a birth date can be cracked in seconds by automated software that tests millions of combinations per second. A randomly generated password that's long and varied makes this approach essentially useless: there's no shortcut to guessing it other than trying every possible combination, which can take centuries with today's hardware.

Privacy: everything happens in your browser

This generator runs entirely locally, in your browser. No generated password is ever sent to a server, stored in a database, or shared with anyone: the calculation happens on your own device, and nothing leaves your screen. You can verify this yourself by checking that no network request is triggered during generation. This is a key point for a tool like this: a password that travels through an external server, even encrypted, is a security risk that's simply better to avoid altogether.

Best practices for your passwords

  • Length matters more than apparent complexity. A 16-character password using only letters and numbers is often harder to crack than an 8-character password packed with symbols.
  • Never reuse the same password across multiple sites. If a single service suffers a data breach, a reused password puts every other account at risk too.
  • Use a password manager. Remembering dozens of unique, complex passwords is impossible for a human. A manager (built into your browser or a dedicated app) stores them encrypted and fills them in automatically for you.
  • Turn on two-factor authentication whenever it's available. Even the best password is safer with a second verification step (a temporary code, a notification on your phone).

Frequently asked questions

Is this generator actually random?

Yes. It relies on the secure random generation function built into your browser, designed specifically for security-related use cases (unlike a basic random number function used for games or animations, which follows more predictable patterns). It's the same type of mechanism used by professional password managers.

What length should I choose?

For a standard account, 16 characters with several character types enabled already offers a very good level of security. For a particularly sensitive account (primary email, banking), you can go up to 20-24 characters without it becoming hard to manage, as long as you use a password manager.

Do I really need to check every character category?

It's not mandatory, but checking several categories (uppercase, lowercase, numbers, symbols) increases the total number of possible combinations for a given length, making the password harder to guess. Some sites also require at least one uppercase letter, one number, and one symbol: in that case, check all four categories.

Is the generated password stored anywhere?

No. Once you leave or refresh the page, the displayed password disappears from your browser's memory for good. Make sure to copy it into your password manager before closing the page if you want to reuse it.
