The Problem

In large organizations, it's overwhelming for admins to find inactive users in the User List of Google Admin Console. These inactive users have not been logged in their Google accounts for a long period. It imposes a potential security risk to the organizational data if these accounts are not taken care of. The User interface does not support advanced filtering or sorting to find these inactive users, so it's fairly time consuming to find these stale accounts.

Inactive users whose last login time is a long time ago

The Solution

The following open source Google Apps Script can automate the process of printing inactive users in your domain.


  1. Open
  2. Click New project.
  3. Name the script project in the title
  4. Copy and paste the following script to the script editor, overwriting existing function myFunction() {} code
  5. Modify the inactiveDays variable to your organization settings. The default is to find any users whose last sign-in is over 30 days. You can set to a number like 60, 180, 365 etc.
  6. Click Services in the left navigation panel
    1. Select Admin SDK API
    2. Click Add
  7. Click Save Google Apps Script project button in the toolbar
  8. Click Run
  9. It will ask for your permissions in the first run
  10. After you grant the permission, the script shall run and print out the results in the Execution log.

const inactiveDays = 30

      maxResults: 100,
      fields: 'users(name/fullName,primaryEmail,lastLoginTime),nextPageToken',
    if (page.users.length === 0) {
      Logger.log('no user found')

    page.users.forEach((user) => {
      const lastLoginTime = new Date(user.lastLoginTime).getTime()
      const diffInDays = Math.floor((now - lastLoginTime) / (1000 * 86400))
      if (lastLoginTime !== 0 && diffInDays >= inactiveDays) {
        Logger.log(`user ${} <${user.primaryEmail}> is inactive for ${diffInDays} days`)
    pageToken = page.nextPageToken
  } while (pageToken)
