Jens Bredigkeit Authentication with embedded login not possible if third party cookies are disabled
We are using the embedded login widget to allow community users to login to our website via external Identity.
Unfortunately the embedded login widget relies on third party cookies, which are disabled in private mode in most browsers.
Is there a way to use the widget with third party cookies disabled?
We have also noticed deprecation warnings about 3rd party cookies in Chrome and Firefox. We are very concerned that browser updates will break the login.
Is this a known issue?
For this behavior, there is no Known Issue.
And our team also mentioned it has been confirmed that third party cookies need to be accepted or those salesforce domains need to be whitelisted as per documentation; https://help.salesforce.com/HTViewHelpDoc?id=setup_domains.htm&language=en_US
If you still have any doubts please raise a case with the salesforce security team so they will review you and answer your query.
I hope you find the above information is helpful. If it does, please mark as Best Answer to help others too.
Thanks.
