A Recovery code or Backup code is a unique code that is usually provided by services, applications, or sites, once 2FA (Two-Factor Authentication) is enabled on an account.

It is important in case you lose access to your 2FA token (lost your phone that has Authy, master, reset, etc.) recovery or backup codes can be used to login to your account without the code from your 2FA token.

• Save to a password manager - very secure, easy
  A password manager is the safest place to store your Backup Codes. We recommend using a trusted password manager such as Bitwarden or KeePass.
• Print backup codes - pretty secure, easy
  print or write down your backup codes, and keep them in a safe place(like with a passport).
• Save and encrypt locally on your computer - very secure, advanced
  Save your Backup Codes locally on a computer only you have access to.

There may be times when you don't have your phone or a security key with you. For these situations, you can print a list of backup codes and keep it in a safe place only you know about, and then sign in with your backup codes.
