This guide details how to complete a Health Check in Casa App using your Trezor One or Trezor Model T device.
First, tap the hardware device icon in Casa App, then tap "Health Check."
Casa will send you an email prompting you to connect your device. The email should come from firstname.lastname@example.org.
Click "Connect Your Device Now" in the email. We recommend Chrome browser.
Once you click the email that Casa sends you from a laptop or desktop computer, you will need to plug in your Trezor device, and unlock it using your PIN.
Plugging in your Trezor device
Once you've plugged in your Trezor device and unlocked it with the PIN, follow the steps in your web browser to sign the Health Check.
Signing in the web browser
When your screen says "Waiting on Trezor," you must approve the Health Check signature from the actual device by reviewing the signature details, and pressing the button on the Trezor device (you must hold down the button on the Trezor Model T) to give it the final confirmation. Once you do this, the signature is applied.
Once you apply the signature from your Trezor device, your Health Check is complete. You've verified that your key is healthy and will be ready to sign when you need it!
