Are generated passwords sent to a server?

No. Passwords are generated locally in your browser with Web Crypto randomness.

What password length should I use?

Use at least 16 random characters for most accounts, or a longer passphrase when you need something easier to type.

Entropy estimates the search space of a random password. Higher entropy means more possible guesses for an attacker to try.

60-89 bits	Good	Acceptable for many ordinary accounts
90-119 bits	Strong	Good default for important accounts
120+ bits	Very strong	Best for admin, vault, and long-lived credentials

Local generationPasswords are generated in your browser with Web Crypto randomness and are not uploaded.

Entropy estimateThe estimate assumes random selection from the available character pool or word list.

Unique passwordsUse a different password for every account and store it in a password manager.

PassphrasesPassphrases are longer but easier to type. They are useful when a password manager is not convenient.

Are these passwords saved anywhere?

No. The page is static and generates passwords locally in the browser.

What is the best default?

For most accounts, a 16 to 24 character random password with uppercase, lowercase, numbers, and symbols is a strong default.

Why avoid ambiguous characters?

Characters like O, 0, I, l, and 1 can be hard to distinguish when typed manually. Avoiding them makes passwords easier to read.
