We are using Auth0 for SSO with our SF community website.
I get several request weekly about failures.
I'd really like to fine an expert to help me clean things up and correct.
The login was setup back in 2020 I believe. I've considered redoing it, but unsure of what I might break. The Google login button also only work occasionally. So there's plenty to deal with. To start with, where might you suggest I start looking to get this issue resolved? Thanks in advance.
Thank you @JFoxUK for your contributions around the Community! Happy to see you engage.
The best places to investigate why these types of logins are failing is of course inside the logs, either on Auth0, Salesforce or on the Google application’s side.
Since you mentioned that these have been configured way back in 2020, it might be a case of legacy integration struggling with modern browser privacy features (like third-party cookie blocking). The setup is likely not configured to handle these new realities, causing inconsistent session management.
I would recommend setting up new connections for the SF SSO and Google in your development environment before modifying them in your production one. If possible, you can try cloning these connections and see if reconfiguring them will fix the flow(or break them completely).
If you have any other questions or updates, let me know!
This is a pretty common situation with Auth0 + Salesforce community setups from that era, especially around token lifetimes, silent auth failures, and the Google social connection breaking due to updated OAuth policies and third-party cookie changes. Nik made a good point about legacy configs not playing well with modern browser behavior.
I have worked through such issues for other clients on several SF community + Auth0 integrations and can help you sort it out without breaking what is already working. Happy to take a look at your setup if you want a second set of eyes.
