Hide M365 previously logged on users when sigining in from Browser

Hi dstryfe024,

Absolutely, I understand the challenge you're facing with the Kiosk PCs displaying a list of previously signed-in users. While Microsoft 365 doesn't provide a native setting to hide this list, you can achieve the desired outcome by configuring your browsers and devices to prevent the caching of user credentials and browsing data. Here are some solutions you can implement:

1. Configure the Browser to Clear Browsing Data on Exit

Microsoft Edge:

• Manually Configure Edge Settings:

  1. Open Edge and go to Settings > Privacy, search, and services.
  2. Under Clear browsing data, click on Choose what to clear every time you close the browser.
  3. Enable Cookies and other site data and Cached images and files.

• Enforce via Group Policy or MDM:

  • Use the ClearBrowsingDataOnExit policy to ensure that browsing data is cleared each time Edge is closed.
  • Reference: https://learn.microsoft.com/en-us/deployedge/microsoft-edge-policies#clearbrowsingdataonexit Edge Browser Policies

Google Chrome:

• Manually Configure Chrome Settings:

  1. Install an extension like Auto History Wipe to clear data upon closing.
  2. Alternatively, instruct users to use Incognito Mode.

• Enforce via Group Policy or MDM:

  • Use the ClearBrowsingDataOnExitList policy.
  • Reference: Chrome Enterprise Policy List & Management

2. Use InPrivate or Incognito Mode by Default

Force the Browser to Always Open in Private Mode:

• Microsoft Edge:

  1. Right-click on the Edge shortcut and select Properties.
  2. In the Target field, add -inprivate at the end.
     • Example: "C:\Program Files (x86)\Microsoft\Edge\Application\msedge.exe" -inprivate
  3. Click OK to save changes.

• Google Chrome:

  1. Right-click on the Chrome shortcut and select Properties.
  2. In the Target field, add -incognito at the end.
     • Example: "C:\Program Files\Google\Chrome\Application\chrome.exe" -incognito
  3. Click OK to save changes.

Note: This will ensure that the browser doesn't save any browsing data between sessions.

3. Implement Browser Kiosk Mode

Microsoft Edge Kiosk Mode:

• Set Up Kiosk Mode:

  1. Go to Settings > Accounts > Other users.
  2. Click on Set up a kiosk (assigned access).
  3. Choose Microsoft Edge as the kiosk app.
  4. Select Public browsing as the browsing mode.
  5. Complete the setup process.

• Benefits:

  • Runs Edge in a restricted mode.
  • Does not save user data or browsing history.
  • Prevents access to other apps and settings.

4. Disable "Stay Signed In" and Persistent Cookies

While this won't hide the list of previously signed-in users, it ensures users aren't kept signed in:

• Microsoft Entra ID (formerly Azure AD) Settings:

  1. Sign in to the https://entra.microsoft.com Entra admin center.
  2. Navigate to Microsoft Entra ID > Users > User settings.
  3. Under Manage user authentication settings, set Users can allow apps to remember user sign-in info to No.

• Customize "Keep me signed in" (KMSI) Experience:

  • Use Conditional Access policies to control sign-in frequency.
  • Reference: https://learn.microsoft.com/en-us/azure/active-directory/fundamentals/customize-branding#change-the-keep-me-signed-in-experience the "Keep me signed in" prompt
