How to use this password generator
Set the length
Choose how long the password should be. Longer is stronger, so 16 or more characters is a good default for important accounts.
Pick your character sets
Toggle uppercase, lowercase, digits and symbols, or switch to a passphrase made of random words. You can also exclude look-alike characters such as 0/O and 1/l for easier typing.
Generate and copy
A new password appears as soon as you change a setting; press the regenerate button for another one. Then copy it and paste it into the account or your password manager.
What this password generator does (and does not) do
Passwords are created locally with crypto.getRandomValues, the browser's cryptographically secure random number generator. Because everything happens on your device, the passwords you generate are never sent to a server or saved anywhere by this tool.
This tool only generates passwords. It does not store them and it does not check whether a password has appeared in a known data breach. To keep your logins safe you still need a place to save them, such as a dedicated password manager.
Why 16 characters is the default
Sixteen characters is long enough to make brute-force guessing impractical for normal accounts while still being a length most websites accept. Combined with mixed character types, the result is very hard to guess. Raise the slider for accounts that matter most, such as your email or your password manager.
Symbols and numbers
Symbols and digits are on by default. They widen the pool of possible characters, which makes each position harder to guess and satisfies sites that demand a special character. Length still matters more than variety, so a long password without symbols beats a short one with them.
Some sites reject certain symbols or cap the length. If a form refuses the password, switch Symbols off or shorten it and generate again. For a numeric code, use the random PIN generator.
Frequently asked questions
Is this password generator really free?
Yes. It is free and needs no sign-up or account. It runs in your browser.
Are my passwords uploaded or stored?
No. Passwords are generated locally in your browser and are never sent to a server or saved by the tool. Closing the tab discards them.
How long should my password be?
Longer is stronger. For important accounts, 16 characters or more with mixed character types is a sensible minimum.
Do symbols make a password stronger?
They help by widening the character set, but length matters most. Combine symbols and numbers with a long password for the best result.
Does it check if my password was leaked in a breach?
No. This tool only generates random passwords. It does not check breach databases or test existing passwords.
Where should I keep the passwords I generate?
Use a reputable password manager. This tool creates strong passwords, but you still need somewhere safe to store them.
What if a site rejects my password?
Some sites limit the length or ban certain symbols. Switch Symbols off or adjust the length, then generate again.
