Why does my Apple device keep logging me into K4Community Plus under my spouse's account?

Sometimes residents who share an Apple ID account will notice that their K4Community Plus app will suddenly be logged in under their spouse's profile. 

This is due to an Apple feature called Keychain which shares login credentials across Apple devices that are logged in under the same Apple ID. This is meant to be a convenience, but for couples who share an Apple ID, it turns out to be a nuisance and K4Connect doesn't have any way to prevent it.

The only way to resolve this is to either log into your individual devices under unique Apple IDs, or turn off the Keychain feature on one or both of the devices.
