How to: Password Generator
- Choose length and character types.
- Passwords appear instantly – copy one.
- Optionally download the list.
Weak and reused passwords are the most common cause of hacked accounts. This generator uses the browser's cryptographic random number generator, so passwords are unpredictable and never leave your device.
Common uses
- Create a unique password for every new account.
- Generate a strong password for an encrypted PDF or ZIP.
- Create Wi-Fi passwords that are hard to guess.
Tips for best results
- 16 or more characters with mixed types is a good default.
- Store passwords in a password manager rather than a document.
- Never reuse a password across sites.
What makes a password strong
Length matters most: each extra character multiplies the number of possible passwords. A random 16-character password with letters, numbers and symbols would take an attacker longer than the age of the universe to guess by brute force.
