JSON is a file format for storing and sharing data that uses human-readable text. Your JSON backup file is named like this: your_account_address.json. Unlike your mnemonic phrase, your JSON backup file is password-protected. It has all the information to restore your account, but you cannot just read it because it is encrypted for safety. To restore your account with the JSON backup file, you must have both the file and the password to decrypt it. If you don't have a backup file yet, you can create it for your account or all of them at once.

• You can save your JSON backup file on any electronic medium. It's safer to store it on a USB drive than on a device connected to the internet.
• You can make several copies of the backup file and store them on different devices in case one of them gets damaged.
• Your backup file is only as secure as the password you used to encrypt it. The recommended way to create passwords is with a dedicated password manager app. It can create random, unique passwords and store them securely.
• Otherwise, you can use a password of random four to five words. These are nearly impossible for computers to guess due to the number of combinations possible but are much easier for humans to remember.
• Do not reuse your password for any websites or apps.
• Do not store your password in the same place as your backup file.
