How to setup Guarda wallet
 
Quote:1. Create your wallet: Setting up the wallet is really easy and simple. It has a user-friendly interface to make the process simple to follow. Go to the Guarda website and click “Create Web Wallet,” you will then be taken to the next page to set up your password to access your wallet 
2. Set your password: Create a strong, unique password that you don’t use elsewhere. The password will be used to decrypt your private keys and grant you access to your wallet — so make sure it’s a strong password, then write it down on some paper and store it away safely  
3. Download a backup: Next, you will be asked to download a backup file. This will be a text file containing your private keys. You will need this to access your wallet, so make sure you keep it somewhere separate from your password to make sure your security is not compromised. 

Remember to download your backup text each time you make a transaction
