Password Generator: create secure passwords

Yes. The Password Generator runs directly on this page in your browser, with no account, sign-up, or installation. You can generate as many passwords as you need.

Set the length between 8 and 64 characters above and choose the character types. The generator creates a new password as soon as you change a setting. Use the refresh icon to generate another with the same settings. Select “Copy password” to copy it to your clipboard.

The generator supports 8 to 64 characters and starts at 20. We recommend at least 16 characters, or 20 or more for email, password managers, and server access. With all four character types, 8 characters provide about 51 bits, 12 about 76 bits, 16 about 101 bits, and 20 about 127 bits.

No. Your password is generated entirely in your browser using the cryptographically secure Web Crypto API (crypto.getRandomValues()) instead of Math.random(). There are no server requests, storage, or logging. If you close the tab without copying the password, it's gone.

Strength is entropy in bits: length × log2 of the character pool selected in your settings. Below 45 bits, the tool shows “Weak”; from 45 bits, “Medium”; and from 75 bits, “Strong”. At 20 characters with all four character types, that's about 127 bits.

Uppercase A–Z, lowercase a–z, digits 0–9, and special characters !@#$%^&*()-_=+[]{}? can each be toggled separately. At least one character comes from each selected type; the rest come from the combined pool, then all characters are shuffled. If a form doesn't accept special characters, uncheck them and increase the length.

This option excludes 0, O, 1, l, and I from all character sets because they are easy to confuse in many fonts. This helps when you need to type a password manually, such as a Wi-Fi password on a router. The smaller character pool slightly reduces entropy.

Yes. If a service is hacked, attackers automatically try the same credentials on other services (credential stuffing). Store your random passwords in a password manager instead of memorizing them. This generator doesn't create memorable passphrases from words; it creates passwords from individual characters.
