Where does UBports 'remember' adb authorizations?

circ

Where/ how does UBports store auth info for adb? I remember having to tell the device that the host it was connected to was trusted early on in the install/early boot, but I want to try to remove any auth that might be on the device now, to try to force a re-authorization process....

I have tried deleting the adb key/pub in ~/.android hoping it require a new auth, but no luck (adb regenerates them)

I'm tracking down a problem with adb backup from here : https://forums.ubports.com/topic/1725

thanks @Lakotaubp - maybe @advocatux can help my N5 forget my host machine....

I've removed /data/misc/adb/adb_keys from the device (adb root, adb shell, rm -rf /data/misc/adb/adb_keys).

N5 in Recovery mode
then plug it in

adb backup -apk -obb -shared -all -f ./current.ab
# Now unlock your device and confirm the backup operation...

momentary flash on UBports recovery screen of "Backup in progress...."

a note that the topic in the OP has more details, but adb backup is completely broken for me on pureOS (debian).
