The ability to remote-wipe a device is usually built in to modern smartphones and tablets, and gives you the ability to choose to delete everything on a device yourself. This is often linked to using the operating system provider's "Find my..." service.
You may want to do this if you discover a device has been stolen and should do this if University data is potentially involved. This is a good reason to make sure that anything important is backed up and/or stored on a server rather than on your mobile device.
Please contact the IS Helpline for assistance if you cannot remotely wipe the device using the operating system provider's mechanisms.
Operating system supplier documentation for iOS/iPadOS and Android are linked below; for other types of device refer to the supplier's support web pages, or do an appropriate web search.
