I have an application that requires user sign in and I also have a list of specific authorized users. Yet, when I check out my usage statistics I get a user that is designated as ‘guest_’. Should I be concerned about potential unauthorized access or is there something else that is causing this?
According to this paragraph on the Monitor report, I would be concerned.
You may see users on this list identified as “guest” users. A guest user is recorded whenever your app is used and the person using it is not signed in. Since we do not have signin information, instead we rely on identifying the device/browser being used. As a result, if Sarah uses the app once from a phone, once from another tablet, and once from her desktop, AppSheet would count this as three guest users. If you are on a per-user subscription plan (AppSheet Starter, AppSheet Core), please make sure all your deployed apps require user authentication (i.e. force users to sign in). Please be aware that the information shown in this chart is from the last 30 days of usage, so even if you make a change today, it may take up to thirty days for old guest user information to stop showing.
But I just checked mine and have the same. Now, I’m concerned
