Deactivate Browser Password Managers Using Device Management

This article will direct you on how to disable various web browser's built-in password managers using group policy. These steps will help prevent corporate logins from being saved and synchronized to personal accounts. You may also consider deploying the Bitwarden browser extension to all browsers as part of this same policy.

How to check if it worked?

Check that the previous steps worked correctly for your setup:

On a user's computer, Open the command line, and run:
gpupdate /force.
Open Edge, then click the three dots for settings ... → Settings → Passwords.
Ensure "Offer to save passwords" is turned off and managed by the organization.

note

Sign-in automatically is still checked because there is no policy setting to turn this off.

Any logins previously saved in Edge will not be removed and will continue to be displayed to the user, despite autofill being disabled. Be sure to instruct the user to import any saved logins into Bitwarden before deleting them from Edge.

On a user's computer, Open the command line, and run:
gpupdate /force.
Open Chrome and click the profile icon on the top right. See that the user is not signed in.
Open Chrome, then click the three dots ... → Settings → Passwords. See that Offer to save passwords is unchecked and managed by the organization.

On a user's computer, Open the command line, and run:
gpupdate /force.
Open Firefox and select Logins and Passwords from the menu bar.
Ensure that a "Blocked Page" message is displayed.

Disable on Linux

To disable the Chrome Password Manager via group policy:

Download the Google Chrome .deb or .rpm for Linux.
Download the Chrome Enterprise Bundle.
Unzip the Enterprise Bundle (GoogleChromeEnterpriseBundle64.zip or GoogleChromeEnterpriseBundle32.zip) and open the /Configuration folder.
Make a copy of the master_preferences.json (in Chrome 91+, initial_preferences.json) and rename it managed_preferences.json.
To disable Chrome's built-in password manager, add the following to managed_preferences.json inside of "policies": { }:
```
Plain Text
{
  "PasswordManagerEnabled": false
}
```

Create the following directories if they do not already exist:

Plain Text
mkdir /etc/opt/chrome/policies
mkdir /etc/opt/chrome/policies/managed

Move managed_preferences.json into /etc/opt/chrome/policies/managed.
As you will need to deploy these files to users' machines, we recommend making sure only admins can write files in the /managed directory.
```
Plain Text
chmod -R 755 /etc/opt/chrome/policies
```
Additionally, we recommend admins should add the following to files to prevent modifications to the files themselves:
```
Plain Text
chmod 644 /etc/opt/chrome/policies/managed/managed_preferences.json
```
Using your preferred software distribution or MDM tool, deploy the following to users' machines:
1. Google Chrome Browser
2. /etc/opt/chrome/policies/managed/managed_preferences.json

note

For more help, refer to Google's Chrome Browser Quick Start for Linux guide.

To disable the Firefox Manager via group policy:

```
The following commands must be executed as root, or preceded by sudo.
