Password Toolkit

Generate strong passwords, create memorable passphrases, and check strength directly in your browser. Generated values and strength checks never leave the page, are not sent to the server, and are not stored in server memory.

Password mode creates a random character-based password with adjustable rules and shows an entropy-based strength estimate.

Length 0
Estimated entropy 0 bits
Strength Fair
Profile Password
20

Longer passwords increase the search space quickly, especially when you mix multiple character groups.

Character options

Lowercase letters are always included so every password has a baseline character set. Pronounceable mode keeps the result more readable while still adding optional numbers or symbols.

Why it is private

Generation and strength checking happen inside the browser, so the server never receives your passwords or passphrases.

What this toolkit covers

  • Creating unique passwords for different accounts.
  • Generating memorable multi-word passphrases.
  • Generating more readable pronounceable passwords with optional suffix characters.
  • Checking an existing password or passphrase with a local entropy-based estimate.

Passphrase note

Passphrases are generated from a built-in local word list and can be easier to type and remember than a dense character string while still offering good entropy when they are long enough.

Strength checker note

The checker gives a local estimate based on length, character variety, and common weak patterns. It is a useful guide, but no browser-only estimator can prove a password is perfect.

Practical tip

  • Use a password manager for random passwords.
  • Use longer passphrases when you want something you can type by hand.
  • Avoid reusing generated values across accounts.
