Log-in-as via Incognito window

The Log-in-as via Incognito window plugin enhances the standard Moodle “Log in as” feature. Instead of switching users within the same browser session, it opens the impersonated session in a new Incognito window — keeping the admin session active in the main window and avoiding the need to log back in afterwards.

Features

• “Log in as” opens in a new Incognito window — no repeated logins for administrators
• Admin session remains active in the main window in parallel
• Incognito mode isolates the “Log in as” session from normal LMS use

Known limitations

• In Safari, “Open in New Private Window” is only available when already in a private window
• In Chrome and Edge, Incognito windows share a single session — only one “Log in as” session can be active at a time
• Course-level “Log in as” is not supported
• The generated link expires after fifteen seconds, which may be an accessibility concern
• Mobile and tablet browsers may not be fully supported

Installation

Tip

If you are setting up a new site or evaluating MuTMS, the MuTMS distribution is the easiest option — it includes Moodle and all MuTMS plugins pre-configured.

This plugin has no dependencies. Install it from the Moodle plugins database or via Git:

For Moodle 5.1.x, clone the plugin into public/admin/tool/muloginas instead. Use MOODLE_500_STABLE for Moodle 5.1.x.

git clone -b MOODLE_405_STABLE https://github.com/moodle/moodle.git
cd moodle
git clone -b MOODLE_405_STABLE https://github.com/mutms/moodle-tool_muloginas.git admin/tool/muloginas

Then continue with the standard Moodle installation.
