Password basics
Why random passwords are useful
People are naturally good at creating memorable patterns, but memorable patterns can also be predictable. Names, dates, keyboard shapes, repeated words, and small variations of an old password are all easier to guess than truly random strings.
A randomly generated password avoids those habits. When paired with a password manager, it also removes the need to remember dozens of unrelated passwords.
One account, one password
Reusing the same password across multiple websites increases the damage if one service is compromised. Unique passwords help contain that risk.
How Passwoo creates randomness
Passwoo uses the browser's crypto.getRandomValues() function and unbiased rejection sampling. Every selected character comes from cryptographically secure random bytes supplied by your browser. The generator never relies on Math.random().
The password itself does not need to leave your device. Generation, strength estimation, and copying all happen locally in the page.
Choosing a useful password format
Random character passwords are ideal when a password manager will store and autofill them. If you prefer to compare other formats or generator styles, GenerateMyPassword.com has additional approaches.
Some sites have unusual rules for symbols, maximum length, or allowed characters. If one generator format does not fit a particular account, exploring different password generator options can be useful.
Practical password habits
- Use a unique password for every important account.
- Choose longer passwords whenever the service permits them.
- Store generated credentials in a reputable password manager.
- Enable multi-factor authentication when it is available.
- Never reuse a breached password on another account.

FAQ
Questions about Passwoo
Does Passwoo store generated passwords?
No. Passwords are created locally in your browser. Passwoo does not maintain a database of the passwords you generate.
How long should a password be?
Longer passwords generally provide more resistance to guessing. When a password manager is handling storage and autofill, using a long unique random password is a strong default.
What does “exclude visually similar characters” do?
It removes characters such as uppercase I, lowercase l, uppercase O, lowercase o, zero, one, and the vertical bar. This can make a password easier to read or type manually.
Can I use Passwoo without an account?
Yes. No registration or login is required to generate passwords.
