Enforce Office 365 Identity for Yammer

Enforcing Office 365 identity ensures seamless SSO across all Microsoft 365 services, eliminating the secondary manual sign-in prompt specifically for Yammer.

When Microsoft 365 applications use SSO but Yammer requires manual authentication, it indicates that Office 365 identity is not fully enforced for the Yammer network. Enforcing this policy links Yammer directly to the Microsoft 365 authentication token.

1
Access the Microsoft 365 Admin Center

Sign in to the Microsoft 365 admin center using an account with global administrator privileges.

2
Open Yammer Network Settings

Navigate to the Yammer or Viva Engage admin center from the available list of administrative portals.

3
Navigate to Security Settings

Go to the 'Network Admin' section and click on 'Security Settings'.

4
Enforce Identity

Locate and check the option to 'Enforce Office 365 identity in Yammer', then save your changes.

5
Restart and Test

Restart the digital signage device to clear active sessions and test the automated sign-in flow to confirm the manual prompt is gone.

Enforce Office 365 Identity for Yammer
Seamless Access: Once enforced, Yammer will rely entirely on Microsoft Entra ID (formerly Azure AD) for authentication, allowing your digital signage to bypass the manual login screen.

Frequently Asked Questions

Why does Yammer ask for a password when Microsoft 365 signs in automatically?

This happens when Office 365 identity is not strictly enforced within the Yammer network settings. As a result, Yammer falls back to its own separate authentication flow instead of using the active Microsoft 365 SSO token.

Is there a specific URL parameter to force Yammer SSO without user interaction?

Currently, there is no officially documented URL string that independently forces Microsoft 365 authentication and seamlessly redirects to Yammer without any user interaction. Enforcing Office 365 identity globally is the recommended solution.

Can I use Okta to bypass the Yammer sign-in screen on digital signage?

Okta can pass the correct authentication tokens as long as the digital signage user is assigned to the appropriate application groups and Office 365 identity is enforced. Ensure your generic signage account is actively assigned to both M365 and Yammer in your Okta portal.
