Unsolicited Password Resets.
Mobile app and web portal.
We have traced this issue to unsupported apps and extensions that have been written for School Loop. These were not written by us and we cannot support them.
Please turn off or uninstall all of these (in both the mobile device (apps) and browser (as extensions).
A quick Google search about managing extensions should help for your specific browser.
Uninstalling the extensions will not allow unsolicited password resets.
