Shared device sign-out: Many Firstline Workers use a single tablet or mobile device that is shared between shifts. This can pose unique security challenges to the organization when different employees who have access to different types of data use the same device over the course of a day. With shared device sign-out, Firstline Workers will be able to log out of all their Microsoft 365 and custom applications and browser sessions with one click at the end of their shift—preventing their data as well as any access to customer data from being accessible to the next user of that device.
-
Chat retention policies (data preservation and deletion): By Default, Content is retained forever. But this can be changed with policies; 1 day delete; one month delete; one year delete; 7 years delete.
