"Login to dashboard" is a new QR code login system. It allows you to use your mobile application (where you are already logged in) for quick login to the web dashboard on your browser by only scanning the QR code.
To use this feature, you will first need to do the following:
Activate 2FA on your minerstat dashboard. Detailed instructions for setting up 2FA are available here.
Install the minerstat mobile app for Android or iOS.
Login to your mobile app.
Then to use this feature, follow the next steps:
Open your minerstat mobile app.
Click on the menu icon in the top right corner.
Click on the "login to dashboard" button (the biggest button with an icon on the top of the menu).
