Customer Reviews

Does what it says it does in a very usable manner.

I use it regularly. I like how it automatically saves the generated password to the clipboard and also how it saves a list of the websites you enter. For security, when you switch to another app it deletes both the password that you entered as well as the generated password. The generated password stays in the clipboard though so you can paste it where you want it elsewhere. If the app was better looking, I would give it five stars.

Tip: I actually modify the website names in a fixed way (e.g. delete the last letter) when I input them into the generator so that if my hashed password is discovered for a particular account due to a cyber attack, they won't be able to back out my input password because they won't know the real website address that I used to generate the hashed password.

Simple and effective

Works as advertised. It would be nice to be able to save a password so it doesn't have to be entered in, but that is far less secure.

The few negative reviews indicate that those particular users were confused with this tool. If you are unfamiliar, research pwdhash.


Elegant solution so strong passwords that you dont need to remember. Available anywhere, never stored nor transmitted and completely dynamic passwords are a must and Keygrinder helps do that in the easiest way.

Thank you for this, it has changed my password habits forever.
