How to configure a backup signing account

Step by step instructions on how to use the Tangem backup xApp

Understanding the process before you get started

The Tangem Backup xApp is designed to simplify the process of creating a regular key between two Xumm (Tangem) cards. By doing this, you will effectively configure one of the cards as a "backup" to the other one. This is not a cloning process where you would make a duplicate a card, this process configures one of the cards to be able to sign transactions on the other card's account.
Don't worry if you can't quite understand it at first. This article will walk you through each step of the process and provide lots of pictures to help.

What we are trying to achieve...

To start, you should have two Xumm (Tangem) cards. Notice that the two cards appear differently...
From now on we will refer to the cards as your Primary card and your Signing Card.
It doesn't matter which one you choose to be your primary or signing card since they are functionally identical, but most people choose the blue card as the Primary card and the transparent card as the Signing card.
When we are done with this process, you will have created an XRPL account on your Primary card, activated it with at least 10 XRP and have created a "link" between your Primary card and your Signing card.
Ideally, you will put the Primary card in a safe, secure place and use the Signing card to sign transactions on the Primary card's account.
If you plan to carry one of the cards with you in your wallet/purse, you would carry the Signing card, not the Primary card.

First things first...

Before you can begin this process, you need to have two Xumm cards and both of them must be imported into Xumm.
This is the number one question we get when it comes to configuring the cards.
This process requires that you have two cards and that each one of them needs to be added into Xumm before you can proceed.
This article provides step by step instructions on how to do this:
Since the blue card is going to be your Primary account, you will need to activate it with at least 10 XRP.
You do not need to activate your Signing account. You just need to import it into Xumm.
