Proposed Changes

I propose adding an mu-plugin that deactivates Jetpack Protect on the fly to avoid showing math questions in the login form.

Before the change, it prevented users from using "WP Admin" auto-login on local sites that have Jetpack installed. When users used "WP Admin", it showed the login form with the math question:

The expected behavior is to get the user automatically logged in to WP Admin, regardless of whether Jetpack is installed.

Testing Instructions

1. Export a site that includes the Jetpack plugin, for example:

• from Activity Log for WoA site
• from Local dev env after installing the Jetpack plugin there

2. Import the site to Studio
3. Open the "WP Admin" link in Studio
4. Confirm that you were logged to WP Admin automatically

Pre-merge Checklist

• Have you checked for TypeScript, React or other console errors?

@wojtekn I am not familiar with this process yet, could you please add more details for:

1. Export site that includes Jetpack plugin
2. Open WP Admin link and confirm that auto-login works - what does it mean Open WP Admin link?
