Parity Signer tutorial with Polkadot-js apps - Wiki Parity Tech Documentation

This tutorial will walk you through setting up a Kusama account with the Parity Signer Android or iOS App and then use this account together with Polkadot-js apps to see your balance and transfer funds or perform any extrinsic from this account.

Summary

2. Setup or recover an account

When launching the app for the first time, no account has been set up yet. At this stage, you will either want to create an account directly from your mobile device or recover an account previously created.

Create an account

Click on the + button and select New Account.

The next screen will allow you to select a network for your account. Kusama is selected by default. You should choose your account identicon and view the related address. Finally, you should define a name for this account. Don’t worry, you can change it later on.

In the next step, your recovery phrase will be presented to you. Think of it as a master key. If you lose it, you lose your money. Write this recovery phrase down and store it in a safe place. If your phone gets stolen/broken/forgotten this will be the only way to recover your account.

You will then be asked to choose a pin code. This pin will be needed later on to unlock your account to sign a transaction.
