ePassGo is a mobile app that allows you to scan QR codes and generate passwords for websites, and it can also be used to participate in a voluntary testing program.

You can register as an entry point with a phone number, email address, or IP address. After registering, you can check the findings of other people and generate passwords for websites. 

When you scan a QR code, you can view the results directly on your device. The results include the website where the code was found, the time of the scan, and a confirmation code. You can also use the confirmation code to check the result of the test.

The app also provides you with the option of adding a contact to your entry point, which will allow you to contact them in the event of an infection.
