Does anyone know exactly what this means?
It means that only users, whoās emails are in a user profile sheet, will be the ones who have access to sign into the app. If a user attempts to sign in and their email is not in the user profile sheet, then they will be denied access.
Ok, but how is that different from the āLimit access to Emails in Sheetā option?
I not 100% sure. I donāt think itās much different. One is a user profile sheet and one is any other sheet. You could probably choose to use āEmails in Sheetā and still choose the user profile sheet. Iāve also thought itās kind of weird to have both options.
Users sheet is a sheet with users who sign in before, another sheet is any emailsā¦ just to keep the list more specific
Another aspect of this may be that the āLimit Access to Emails in Sheetā option will search for any email addresses in any/multiple columns in the sheet, so if you have a flow that allows a user to enter other outside email addresses into that sheet for some reason, it may be inadvertently granting access to outside users that should not have access. Whereas āLimit Access to Emails in User Profileā would be restricted to only those email addresses that are in the specified user profile email column. But thatās just a theory that I have. Itās not something Iāve tried myself and I canāt find any solid documentation that says for sure.
