In Profile > Cogwheel > Security > Devices, it's possible to see which devices are currently signed into your Bunq account - a very important safety feature.
However, in my opinion, the info there is very minimal. My suggestion would be adding when the device was last actively using Bunq, in what country/area, and the ability to rename.
Let me elaborate!
Renaming a device: On Android, devices can have weird names which are unrecognisable for the end user. For example, my phone is the 'Xiaomi 2201122G', which isn't very helpful when trying to find a bad actor within my devices. Being able to rename the device to something allows people to more easily recognise devices.
Seeing when a device has been last active: Your/an old device might still be in the Devices list! By showing when the device was last active, you stimulate people to remove unused devices. You might even make it red if it has been e.g. 6+ months ago.
Location: This makes the most sense to me. If I - as a Dutch person - see someone signed in from another country, I know something's up.
Below is a picture where I showcase what this section currently looks like in the Android app, and a potential concept design on how the enhanced version of this screen could look like, with all features implemented.
