If your administrator has enforced two-factor authentication, it means that two-factor authentication must be used every time you log on to the administrator console and it cannot be disabled. Complete the following steps to set up two-factor authentication before you can access the administrator console.
The Trend Micro Email Security administrator console provides two-factor authentication support. Two-factor authentication provides an added layer of security for the local accounts and prevents unauthorized access to your Trend Micro Email Security administrator console, even if your password is stolen.
After enabling two-factor authentication, local accounts need to provide the following authentication credentials each time they sign in:
Local account and password
A one-time password generated by the Google Authenticator app
This section describes how to set up two-factor authentication with a local account.
If you did not get the verification code, wait for at least 3 minutes before clicking Resend Code.
Download Google Authenticator either from Apple's App Store or Google Play and install it on your mobile phone.
Add your Trend Micro Email Security account to Google Authenticator by scanning the QR code.
Provide the 6-digit code generated by Google Authenticator to verify that your authentication works properly.
Your account will be presented with the two-factor authentication when they try to log on.
If you want to disable two-factor authentication, click Disable on the Two-Factor Authentication screen. If your administrator has enforced two-factor authentication, click Reset to reset two-factor authentication if necessary.
