安裝方式
Minimum Requirements
- PHP 7.4 or greater is recommended.
- MySQL 5.6 or greater is recommended.
Automatic installation
Automatic installation is the easiest option — WordPress will handle the file transfer, and you won’t need to leave your web browser. To do an automatic install of Secure 2FA, log in to your WordPress dashboard, navigate to the Plugins menu, and click “Add New.”
In the search field, type “Secure 2FA” and click “Search Plugins.” Once you’ve found it, you can view details such as the point release, rating, and description. Most importantly, you can install it by clicking “Install Now,” and WordPress will take care of the rest.
Manual installation
The manual installation method requires downloading the Secure 2FA plugin and uploading it to your web server via your favorite FTP application. The WordPress codex contains [instructions on how to do this here](https://wordpress.org/support/article/managing-plugins/ #manual-plugin-installation).
常見問題集
-
How do I enable and configure Secure 2FA?
-
After activating the plugin, a “Secure 2FA” menu item will appear in your WordPress admin dashboard’s sidebar.
-
Can I disable enforcement 2FA for specific user roles?
-
Yes, you can configure enforce 2FA settings to exclude certain roles from 2FA enforcement.
-
How Can I exclude specific users from enforced two-factor authentication?
-
There is no settings page available for excluding users from forced two-factor authentication. However, you can exclude specific users by adding the following filter to the “functions.php” file of your active theme:
<?php add_filter('secure_tfa_enforce_tfa_excluded_users', function() { // User ID(s) you want to exclude return [1]; }); -
What happens if a user doesn’t receive the OTP?
-
If a user doesn’t receive their OTP, they should:
- Wait a few minutes and try again.
- Use their backup recovery codes to regain access if OTP delivery fails.
- If the issue persists, the site administrator can assist with troubleshooting by checking the activity logs for the user or deactivate 2FA for that user.
- If you are the site administrator, check the

Handling and Troubleshooting Issues
-
If you’re facing issues logging in or not receiving OTPs due to 2FA method issue or email or API problems, and you need to regain access to your WordPress account, you can configure the following constants in the
config.phpfile to help resolve these issues:define( 'SECURE_TFA_DISABLE_PLUGIN', true ) ;This constant disables the 2FA login process and temporarily deactivates its functionality, although the plugin remains active.
define( 'SECURE_TFA_DISABLE_ENFORCE_TFA', true ) ;This constant disables the enforced 2FA requirement for users who have not yet enabled it.
