Using the data supplied by Troy Hunt and his Have I been pwned? website Pwned Pass allows you to check to see if any password has appeared in a data breach.
Pwned Pass is a simple Xamarin app that allows you to type in a password and tells you if it has been used in a data breach.
Troy Hunt of Have I Been Pwned? recently added a new API to his website which allows you to search his extensive database of pwned passwords, 306 million of them. I have simply created a Android/UWP frontend to this API.
It should be noted: Do not send any password you actively use to a third-party service – even mine! I don’t log anything that you type into my app and this app makes use of the k-anonymity feature to avoid transmitting passwords.
As well as using Troy’s new API I also take advantage of his existing API’s. You can search his extensive database of email addresses to see if you have been affected by a data breach all from my android app.
