$last_login = $auditor->get_last_login( $user_id );

if ( $last_login ) {

User Tools adds missing features to user management, such as basic user activities, including last login, registration dates and user switch from the User administration screen. You can deactivate users without deleting them, allowing you to maintain your ownership of past user activity and content.

<h3>PRIVACY STATEMENT</h3>
This plugin makes use of a single browser cookie in order to allow users to switch between accounts. The cookie contains only a secure reference hash and does not store any personally identifiable information (PII). The actual user data is stored securely on the server using WordPress transients.
The cookie name is: wp_usrtk_user_switch_ref
This implementation ensures that no user data or PII is exposed in the browser cookies, making it more secure and privacy-friendly. The cookie is set with HTTP-only flag, secure flag (when HTTPS is in use), and SameSite=Strict for enhanced security. The cookie expires after 24 hours or when the user switches back to their original account.
How can I report security bugs?
You can report security bugs through the Patchstack Vulnerability Disclosure Program. The Patchstack team help validate, triage and handle any security vulnerabilities. <a href="https://patchstack.com/database/vdp/user-toolkit" rel="nofollow ugc">Report a security vulnerability.</a>

User Toolkit

Very useful functionality and expertly executed. Thanks for your work here!

FANTASTIC Plugin


WordPress needed this. There are similar plugins but this one seems cleaner, and has more/better features.



I have an issue though. I have three WordPress installations currently. With one of them the user-switching feature works. With the other two, it does not. I will click switch user and it redirects to the front end of my site but I am still logged in as the admin.



One of the two that doesn't work has very few plugins installed which initially is making me lean away from it being a plugin conflict.



I'm wondering if it's a cookie issue. If I use the feature on one site and it sets a browser cookie, then I go to another WordPress site to use the same tool, could there be a cookie conflict?



My only advice right now, if you have not yet, is to try testing this plugin with multiple live WordPress sites. I'm really hoping this can get figured out because I love all of the other features and information the plugin gives my users page.
