Want to know how strong this password really is?

Registered users are provided a Strength Index for every password they generate.


What the heck is this?
It's a random password generator. See the "what?" page for more information.

Aren't there already password generators out there?
Yes, but they all bugged me. See the "why?" page for more information.

Are these passwords really impossible?
No. Any can be breached given enough time and resources, but the Impossible Password Generator lets you make your passwords as close to impossible as you like.

Is it safe?
This password generator is safe to use, or at least as safe as any other online password generator. See the "how?" page for more information. You can also register for free to use this site over HTTPS, which helps edge us out over some other generators. Plus, that gets you access to some other cool features such as our Strength Index API.
