You will be able to restore your account on any device, if you have your password and backup code. Your backup is encrypted with AES, and the key to that encryption is your password. This means that on its own, your backup does not reveal any crucial information to a third party, and they will not be able to use it to access your funds.
Go to the menu (three lines in the upper left corner).
Press on Backup & Restore.
You will be prompted to download or to copy your backup code.
!Please pay attention where you download and keep it: choose a safe place and share it with no one. Do not keep it together with your password! Remember that no Guarda team member will ever ask you to provide your backup code.!
