What do I absolutely need to keep in mind about Multi-Factor Authentication (MFA)?

  • Security: Keep your device in a secure space. The security of the authenticator app depends on the security of your device.
  • Backup: Many authenticator apps offer the option to create a backup. Use this feature to retain access to your codes, even if you change or lose your device.
  • Secret key: When setting up the authenticator app, a so-called secret key is generated – a random sequence of characters. By securely storing this key in a password manager, you can more easily restore your authenticator later – for example, if your device is lost or damaged.
  • Multiple accounts: You can add multiple accounts to your authenticator app. Use clear labels to distinguish them easily.
