  3. Using Authentication Apps Versus SMS Codes

  • Authentication Apps (Preferred):

    • Apps like Google Authenticator or Microsoft Authenticator generate time-based codes that are more secure than SMS.
    • These codes do not rely on your cellular network, making them safer from SIM-swapping attacks.

  • SMS Codes (Backup Option):

    • SMS-based MFA sends a code to your phone via text.
    • Use this method only if an authentication app isn’t available.
