Configure Two-Factor Authentication Using Email

This topic describes how to configure two-factor authentication using email.

Note: The configurations of two-factor authentication is applied to all your Linkus clients.


  1. At the top-right corner of Linkus Desktop Client, click your account, then go to Change Password & Security > Security Settings.
  2. Select the checkbox of Two-Factor Authentication.
  3. In the pop-up Password window, enter your account password and click Confirm to verify your operation.
  4. Select Authenticated by Email, and complete the following settings:

    1. Click Send.
      An email containing a 6-digit authentication code is sent to the email address that you use to log in.
      Note: The code expires 5 minutes after the email is sent.
    2. In the Authentication Code field, enter the authentication code.

    3. Click Save.


  • The webpage prompts a message "Edited successfully.", which means that you have successfully set up two-factor authentication.
  • Next time you log in to Linkus UC clients (Web Client, Desktop Client, and Mobile Client) using the email addressand password of your extension account, you need to enter an authentication code additionally.
    Note: In later use, if the email address associated with your extension is changed, the two-factor authentication will be disabled automatically.
Troubleshooting: What if I fail to log in with two-factor authentication?

If you lose access to your two-factor authentication (e.g. you lost your device or could not receive authentication code via email), contact system administrator to disable the two-factor authentication for your account, so that you can directly log in with your email address and password.
