What Is a Password Generator?

A password generator creates a random string of characters that is far harder to guess than anything a person would typically choose, drawing from uppercase letters, lowercase letters, numbers and symbols in whatever combination you select.

Randomly generated passwords avoid the predictable patterns — names, dates, keyboard walks, reused words — that make human-chosen passwords vulnerable to guessing and credential-stuffing attacks, which is why security guidance consistently recommends using a generator together with a password manager.

Astuces

Use a Password Manager

Save generated passwords in a password manager rather than trying to memorize them.

Use at Least 16 Characters

Longer passwords are significantly harder to crack — 16 characters or more is a good default.

Questions Fréquentes

Character selection uses your browser's cryptographically secure random number generator (Web Crypto API), the same kind of randomness used for cryptographic keys.

No — the password is generated and displayed entirely in your browser and never transmitted over the network.

Longer is generally better — 16 characters or more is a reasonable default for most accounts, more for highly sensitive ones.

Only if you expect to need to type the password manually — otherwise, including them slightly increases randomness.

No — nothing is stored; copy the password into a password manager right after generating it.

Length generally contributes more to strength than complexity alone, though both matter — this tool lets you control both.
