@mark-robustelli thanks for the documentation link. I used a version of the "Logout Requirements" example to redirect to an endpoint that removes any fusionauth.known-device.* cookies before redirecting back to the application.

Do you think the Hosted Backend should remove fusionauth.known-device.* cookies when it removes the other tokens, at least in the case where fusionauth.remember-device is false?

Otherwise, it seems certain we will hit the HTTP 431 error whenever an application is accessed on a shared device with ~100 users. Or is the Hosted Backend not something FusionAuth envisions people using in production?
