Enter the management password to access the Google Sheets login log controls.
This page is set up to work with the shared Google Sheets login log.
Use the Google Sheet as the shared audit log for site activity. The homepage writes login and logout events to that sheet through the Google Apps Script web app.
Update the GOOGLE_SHEET_URL constant in this file after you create the sheet.
Keep this page discreet at the bottom of the homepage, and use the Apps Script deployment URL in the homepage file so all users write to the same shared sheet.
