Single Sign On to third party sites

[buszi99]

Hi, is it possible to somehow do a Single Sign On on SharePoint Online ? I mean when users logs in to his account in office he will be logged to third party sites automatically.

Best regards

If the third party website is configured for SSO, then yes:

Single sign-on usually uses a certificates to auth, so it should. But as said, the app/site needs to support it :)
