Deployment methods
Enterprise
Group Policy (GPO)
Windows Active Directory environments. Uses Chrome ADMX templates. Best for on-prem AD.
macOS
JAMF Pro
Deploy via mobileconfig profile. Works for macOS fleets managed with JAMF.
Small teams
Manual install
Install from Chrome Web Store, enter Account ID in popup. No admin tooling required.
Method 1 — Microsoft Intune
1
Create a Chrome extension configuration policy

In Intune Admin Center: Devices → Configuration → Create → New policy → Windows 10+ → Settings catalog

Search for ExtensionInstallForcelist and add this value:

pnpcomkpinmnhhlajjimcflfflnpbaej;https://clients2.google.com/service/update2/crx
What this does: Force-installs the extension. Users cannot disable or remove it.
2
Configure auto-enrollment (optional — skip for manual enrollment)

To pre-configure the Account ID so users don't need to enroll manually, add an ExtensionSettings policy:

{
  "pnpcomkpinmnhhlajjimcflfflnpbaej": {
    "installation_mode": "force_installed",
    "update_url": "https://clients2.google.com/service/update2/crx",
    "managed_storage": {
      "mbr_account_id": "YOUR_ACCOUNT_ID",
      "auto_enroll": true,
      "mbr_org_name": "Your Company Name"
    }
  }
}
Replace YOUR_ACCOUNT_ID with your membrAIn account ID from the portal (Settings → Account).
3
Assign policy to device groups and sync

Assign the configuration policy to your target device group. Extension installs on next Intune sync (typically within 8 hours, or force sync via Company Portal).

Verify: After sync, open Chrome on an enrolled device. The membrAIn icon should appear in the toolbar. Check the portal → Active Devices to confirm enrollment.
Method 2 — Group Policy (Windows AD)
1
Install Chrome ADMX templates

Download Chrome ADMX templates from chromeenterprise.google. Copy to your domain's PolicyDefinitions folder:

# On your Domain Controller:
Copy-Item "chrome.admx" "C:\Windows\SYSVOL\domain\Policies\PolicyDefinitions\"
Copy-Item "chrome.adml" "C:\Windows\SYSVOL\domain\Policies\PolicyDefinitions\en-US\"
2
Configure force-install policy

In Group Policy Management Editor:

Computer Configuration → Policies → Administrative Templates → Google → Google Chrome → Extensions → Configure the list of force-installed apps and extensions

Enable the policy and add:

pnpcomkpinmnhhlajjimcflfflnpbaej;https://clients2.google.com/service/update2/crx
3
Configure managed storage for auto-enrollment (optional)

To pre-configure Account ID via registry:

# Deploy via GPO Preferences → Registry
Key: HKLM\SOFTWARE\Policies\Google\Chrome\3rdparty\extensions\pnpcomkpinmnhhlajjimcflfflnpbaej\policy
Values:
  mbr_account_id  REG_SZ  YOUR_ACCOUNT_ID
  auto_enroll     REG_SZ  true
  mbr_org_name    REG_SZ  Your Company Name
Method 3 — JAMF Pro (macOS)
1
Create a Chrome management profile

In JAMF Pro: Computers → Configuration Profiles → New. Add a Custom Settings payload with this preference domain and JSON:

# Preference Domain:
com.google.Chrome

# JSON value:
{
  "ExtensionInstallForcelist": [
    "pnpcomkpinmnhhlajjimcflfflnpbaej;https://clients2.google.com/service/update2/crx"
  ],
  "ExtensionSettings": {
    "pnpcomkpinmnhhlajjimcflfflnpbaej": {
      "installation_mode": "force_installed",
      "update_url": "https://clients2.google.com/service/update2/crx"
    }
  }
}
2
Deploy managed storage for auto-enrollment (optional)

Add a second Custom Settings payload for the extension's managed storage:

# Preference Domain:
com.google.Chrome.extensions.pnpcomkpinmnhhlajjimcflfflnpbaej

# JSON value:
{
  "mbr_account_id": "YOUR_ACCOUNT_ID",
  "auto_enroll": true,
  "mbr_org_name": "Your Company Name"
}
