To protect against computer failure or software issues it’s good practice to back up your crypto wallet. How you do this will depend on the software you are using. For example, Bitcoin wallets will ask you to generate and record a 12-word backup phrase that you can use to restore your wallet if you lose access. These can sometimes be a 24-word phrase, but the process will be similar with all companies. Make sure you look into what you need to do with your particular software, so you’re ready to back it up when needed.
