Safer Badgers - Encryption Keys and Secret QR code

How do I use the Secret QR code to unlock my data on a new phone?

Your COVID-19 QR secret code represents the encryption keys used to protect your data in Safer Badgers. It is saved locally. Without these keys, your phone will not be able to unlock your test results and reported symptoms, and your building access status will not be updated.

We strongly recommend that you save your QR code now.

! Your QR code contains your testing and health history. This information will be lost if you do not save your QR code prior to uninstalling your app.

! We do not store your private encryption key, QR code, testing history, or health history on our servers. We will not be able to retrieve it for you.

Your QR secret code is used to transfer your encryption keys when reinstalling, or installing on a second or replacement phone.

You should not share this QR code with anyone else.

If you do not save your QR code and lose your testing history, you will have to get tested again.


Transfer your QR secret code between phones

If you reinstall Safer Badgers or get a new phone, you can use the Scan button during setup or in the Settings menu to open the camera and scan the QR code from another display. Depending on the lighting and other factors, you may need to try several times.

  1. On your original phone, tap on the QR Code button in the settings menu. Your secret QR code will open.
  2. On your new or replacement phone, tap Scan Your QR Code during setup or in the settings menu to open the camera and scan the image.

Save your QR code

Important! If you don't take this step and then reinstall the app later, you will likely lose your testing history. 

You can save your QR code to your phone or connected cloud storage:

  1. Open the Settings menu and tap the QR Code button.
  2. Tap Save on the COVID-19 QR Code screen.

Retrieve your QR code

Should you need to reinstall the app, you can restore your QR code if you backed it up previously. Doing so will restore your access to your testing history.

After you've reinstalled and begun the set up process, you'll see a message stating that it "Looks like you've used this feature before on another device."
