💡 Tip: Length is the most important factor — a long password is always safer.
The password generator creates a strong, random password right in your browser. Adjust the length and character types to suit each service, and you get a hard-to-guess credential ready for any account.
How the calculator works and what it’s for▾
How the generator works
The tool draws characters at random from the sets you choose: uppercase and lowercase letters, numbers and symbols. The more character types you include and the longer the password, the more possible combinations exist and the harder it is to crack.
The password is created locally in your browser, so it is never sent to any server.
What you can adjust
You can set the password length and choose whether to include uppercase letters, lowercase letters, numbers and special characters. That lets you match the requirements of different services.
Tips for safe use
Use a different password for every service so that one leak can't compromise your other accounts. A long, random password is far safer than a short or easily guessed word.
Store your passwords in a password manager so you don't have to memorise them.
Who it's for
The generator suits anyone who wants to protect their online accounts: email, banking, social media and work systems all benefit from a strong, unique password.
