Create strong, secure passwords with custom lengths and character inclusion options.
Length matters more than anything else, because every extra character multiplies the number of possible passwords. With all four character sets switched on there are 88 possible characters, so a random 12-character password carries about 77 bits of randomness and a 16-character one about 103 bits. Both are far beyond guessing or brute force. Eight characters, on the other hand, is within reach of a determined attacker who has stolen a password database.
Use 16 characters or more for important accounts like email and banking. If a site limits the length or rejects some symbols, switch symbols off and add a few extra characters to make up for it.
A password is only as strong as the randomness behind it. This generator picks every character with crypto.getRandomValues(), the browser's cryptographically secure random number generator, and avoids the small bias a simple remainder calculation would introduce, so every allowed character is equally likely in every position. It doesn't use Math.random(), which is fine for games but isn't designed to be unpredictable.
The password is created on your device and never sent anywhere. We can't see it, and it's gone when you close the page.
The meter is a quick check of length and character variety, not a full estimate of cracking time. A password made here with 14 or more characters and at least three character types will always show as strong. What really makes it strong is that it's random and used for one account only. A password manager makes that easy, since you don't need to remember any of them.
It's safe here because the password never leaves your browser. No server is involved, and you could load the page, disconnect from the internet and keep generating. Just use each password for one account only.
The symbol set leaves out characters that often cause trouble, such as quotes, backslashes and spaces, which some websites and command lines handle badly.
It removes characters that are easy to confuse when reading: i, l, 1, L, o, 0 and O. Use it for passwords you'll read aloud or type from paper.
No. Nothing is saved or logged. Refresh the page and they're gone.
