This password generator creates long, unpredictable passwords using your browser’s cryptographic random number generator (crypto.getRandomValues), the same source used for encryption keys. Choose the length and which characters to include, and a new password appears instantly with a strength rating based on its entropy.
Passwords are created on your own device and are never transmitted, logged or stored, so no one else ever sees them. Need many at once for test accounts or a new team? Generate a list of up to 1,000 and download it as a text file.
How to use the Password Generator tool
- Set the length with the slider. 16 characters or more is a good choice for most accounts.
- Pick the character types: uppercase, lowercase, numbers and symbols.
- Tick Exclude look-alikes if you will type or read the password aloud, and list any characters a site does not accept.
- Check the strength meter, then press Copy. Press New for another one.
- For many passwords at once, open Generate many passwords.

What makes a password strong?
Strength comes from length and randomness. Each extra character multiplies the number of possible passwords, so a random 16-character password with letters, numbers and symbols has over 100 bits of entropy, far beyond what any attacker can guess. Short passwords with clever substitutions like “P@ssw0rd” are cracked quickly because attackers try those patterns first.
Use a different password for every account. Then a leak at one website does not expose the others. A password manager makes this easy by remembering them all for you.
How the strength meter works
Entropy is calculated as length × log2(pool size), where the pool is the number of different characters allowed. Below 60 bits is weak, 60–80 bits is good for most online accounts, and over 100 bits is very strong. The crack-time estimate assumes a fast offline attack of 100 billion guesses per second against a leaked password database.
Frequently asked questions
Are the generated passwords stored anywhere?
No. They are created by JavaScript in your browser and exist only on your screen until you copy them. Nothing is sent to a server.
How long should my password be?
At least 12 characters, and 16 or more for important accounts like email and banking. For a password manager’s master password, a long passphrase of several random words also works well.
Is a random password better than a passphrase?
Both are secure if long enough. Random characters pack more strength into fewer characters, while passphrases are easier to remember and type. Use random passwords for anything stored in a password manager.
Why exclude similar characters?
Characters like l, 1, I, O and 0 are easy to confuse when reading a password aloud or typing it from paper. Excluding them slightly reduces entropy, so add a character or two to compensate.
