Create uncrackable passwords or memorable passphrases using your browser’s secure random generator.
What is the Password Generator?
Weak and reused passwords are the main reason accounts get hacked. This free password generator creates strong, random passwords using your browser’s cryptographically secure random number generator (the same technology used by password managers). Nothing is sent over the internet, so the password is known only to you.
Choose a random password with upper and lower case letters, numbers and symbols, or switch to a memorable passphrase like Maple-Rocket-Tulip-Ocean42! that is easy to type but still very hard to crack.
How to use the Password Generator
- Pick random characters or a memorable passphrase.
- Set the length (16+ characters is recommended) and the character types.
- Copy the password and save it in a password manager.
How strong is a generated password?
Strength is measured in bits of entropy – the number of guesses an attacker would need. Each extra character multiplies the guesses. A 16-character password using all four character types has about 100 bits of entropy, which would take billions of years to brute-force with today’s hardware.
| Length | Characters used | Strength |
|---|---|---|
| 8 | letters + numbers | Weak |
| 12 | all types | Strong |
| 16+ | all types | Very strong |
Password safety tips
- Use a different password for every account.
- Turn on two-factor authentication (2FA) for email, banking and social media.
- Store passwords in a password manager instead of a notebook or a text file.
- Never share passwords over chat or email.
Frequently asked questions
Is it safe to use an online password generator?
This one runs 100% in your browser with the Web Crypto API. The password is never sent to or stored on our server.
How long should my password be?
At least 12 characters, and 16 or more for important accounts like email and banking.
What is a passphrase?
A password made of several random words, e.g. Maple-Rocket-Tulip-Ocean. Long passphrases are both strong and easy to remember.
Why avoid look-alike characters?
Characters like l, 1, O and 0 are easy to confuse when typing a password by hand.
