Frequently asked questions

How long should a password be?

At least 12 characters for everyday accounts and 16+ for email, banking and password-manager master passwords. Each extra character multiplies the number of guesses needed.

Is it safe to generate passwords online?

Here, yes: passwords are created with crypto.getRandomValues inside your browser and never sent anywhere. You can even disconnect from the internet after the page loads.

What does "entropy bits" mean?

Entropy measures unpredictability. 60 bits takes an attacker making 10 billion guesses per second about 1.8 years on average; 80 bits takes over a million years.

Why exclude ambiguous characters?

O/0 and I/l/1 look alike in many fonts. Excluding them helps when a password must be read aloud or typed from paper, at a small cost in entropy.
