Create a random password with the length and character sets you choose, from 4 to 128 characters. A strength meter scores the result and tells you what to change. The generator runs inside your browser, so the password never travels over the network.
No. Generation happens in the page on your own device, the result is written into a read-only field, and copying it puts it on your clipboard. There is no upload step and no account to create.
Short length, a small character pool, and reuse. A fresh 12-character string is strong until it is used on three sites; then one breach exposes all three accounts. Generated once per account, the same string stays useful.
Put it straight into a password manager and let the manager fill it in later. If you have no manager, write it down on paper and keep it somewhere physical rather than reusing a password you already know by heart.
Use a passphrase where you have to type the secret by hand, such as a password manager master password or a device login, because word sequences are easier to remember. Use a random string where a manager fills it in for you and you never type it.
The generator draws one password at a time. Press Generate again for a new one, or reload the page for a clean slate, then copy the one you want before drawing the next.
They help, but less than most people assume. Moving from letters and digits to the full 88-character pool at 12 characters adds about 6 bits of entropy. Adding four characters to a letters-and-digits password adds more than switching on symbols does.
Twelve characters from all four sets is a reasonable working floor, and 16 is better wherever the site allows it. Length multiplies the search space, so 16 characters from the full pool sit around 103 bits of entropy against roughly 78 bits at 12 characters.
The string is built on your device in JavaScript, shown in a read-only field, and never posted to a server, which is the whole point of not emailing a password to yourself.
Send the finished password to the clipboard with a single button and paste it into the signup field or the password manager vault.
Uppercase, lowercase, digits, and symbols switch on and off independently, which keeps the output inside the rules a stubborn signup form will actually accept.
Draw as many candidates as you like, in any combination of settings, and copy the one that fits the account you are creating.
The exclude similar switch removes the glyphs that turn into support tickets when a password is copied by hand or read over a phone.
The password is assembled in the page and never transmitted, so the tool itself is not another copy of your secret sitting on a server.
The strength meter reports a number and the specific change it wants, so a weak result tells you what to fix instead of just refusing it.
Turn sets on and off to match a site that rejects symbols or caps length, and get a password that passes the validation rules on the first try.
Set 16 characters when the policy allows it and 64 when you need a long secret for a service account, without hunting for another tool.
