Managing WordPress application passwords a hassle-free way
Using application passwords as a security measure was introduced in WordPress 5.6. This feature enables you and your users to generate and use separate passwords for accessing website APIs such as REST API. The WP Cerber plugin brings a set of tools to manage application passwords in an effective and secure way. In this article, we will also show you how to monitor the usage of application passwords and how to be notified when a user creates one.
We have to control application passwords
Although using application passwords brings an additional security barrier, the default WordPress implementation of application passwords is minimalistic and has the following issues.
- Application passwords have no protection against brute-force attacks
- We have no ability to disable or enable passwords for a specific user role
- Standard, interactive user passwords can still be used to access website APIs.
- We have no control over the use of passwords due to a lack of logging
Disabling application passwords
If you want to disable application passwords on your WordPress completely, set the “Application Passwords” setting to “Disabled.” This setting is located under the “User Policies” admin menu on the “Global” tab. Once it’s activated, users will no longer be able to create new passwords and use any of the passwords that were generated earlier. For advanced management, please read the rest of the article.
Use WP Cerber to manage application passwords
All the settings are located under the “User Policies” admin menu. To configure the use of application passwords for all users on your website, switch to the “Global” tab. To configure the setting for each user role separately, switch to the “Role-Based” tab. The settings configured for a role have a higher priority.
The WP Cerber setting you need to configure is named “Application Passwords”
The default value of the setting is to permit the use of the application passwords the way how it’s implemented in WordPress. It implies using both, traditional passwords (that users use to log into your website via a login form) and application passwords when accessing website APIs. The setting in this case is “Enabled, access to API using standard user passwords is allowed”.
A more secure, advanced, and recommended way of using application passwords is to permit access to website APIs by using application passwords only. In this case, traditional interactive passwords cannot be used when accessing website APIs, even if the specified one is valid. Any attempt to get access to APIs will be denied. To achieve this, select “Enabled, no access to API using standard user passwords”.
The last and straightforward way of dealing with application passwords is to disable them with the setting set to “Disable”.
Configure settings for a specific user role
All the settings configured for a role have a higher priority than the global ones. So you can disable using application passwords globally for all users and enable them for a specific role only.
The default value for all roles is to use global settings configured on the “Global” tab. In the role settings, this option is named “Use global policies”. This means the role’s setting inherits all the changes made to the global settings.
If you select any other than the “Use global policies” option, that selected option will have an effect on the role instead of a setting configured on the “Global” tab.
Note: the role-based settings are available in the professional version of WP Cerber.
How to monitor application password usage
WP Cerber adds two new columns to the lists of users’ application passwords on their profile pages in the WordPress dashboard. Using links in those columns, you can check the Activity log. The “Authorized” column links navigate you to all logged events of using application passwords by the user. The links in the “Authorization Failed” column navigate you to all failed attempts to use website APIs when the user’s username or email was in use.
How to get notified when a user creates a new password
On the Activity log admin page, you can enable sending an email or a mobile notification when any user or a specified one creates a new application password. Go to the Activity log, select “User application password created” from the first select above the table and click Filter. Now, to enable notifications, you need to click the “Create Alert” button on the right. To configure the email address or the mobile device for notifications, switch to the “Notifications” tab.

How to restrict access to REST API and XML-RPC
WP Cerber offers several options to restrict access and you can configure any combination of them. You can block access to these APIs completely by disabling them; you can permit or block access to these APIs from specific IP addresses by using IP Access Lists. Additionally, you can permit access to REST API for specific roles or to specific namespaces only. By configuring country-based access rules, you can permit or deny access to REST API or XML-RPC by a list of countries.
