2. Set up Cobo Guard  

You will need to create a PIN code and enable Face ID (optional) for your Cobo Guard, and initialize the MPC Node.

  • Create PIN code: The PIN code is used to unlock Cobo Guard and authenticate your identity during transaction approvals.  If you ever lose or forget your PIN code, you will need to uninstall and reinstall Cobo Guard on your current device, followed by re-generating your MPC key share(s). After creating a PIN code, you may also enable Face ID to eliminate the need to manually enter the PIN code each time you use Cobo Guard.
