Security threats are constantly evolving. To protect your ADM account, not only should you be frequently updating passwords and changing the HTTP and HTTPS ports, but you should be enabling two-step verification as well. This adds an extra layer of security by requiring a one-time verification code in addition to your password when logging into ADM. This adds additional protection.
How to Enable Two-Step Verification:
1. Log into ADM: Go to personalization settings and select Enable Two-Step Verification.
