How do you remove permanent adb authorization? I have a Nexus S running Cyanogen 10.1.2 (Android 4.2.2).

I require adb authorization, but I accidentally "permanently" authorized a device. How do I remove the "permanent" authorization, so that every time it asks me again?
If your device is rooted, as it probably is with CM, you can also do this via adb:

adb shell rm /data/misc/adb/adb_keys


Depending on your build you probably have to run adb as root(1) or call the su binary(2).

(1) adb root or adb kill-server; sudo $(which adb) start-server --> adb shell rm /data/misc/adb/adb_keys

(2)adb shell --> su --> rm /data/misc/adb/adb_keys

Or delete this file with a root explorer. If you authorized more than one device open this file and remove the public key of the desired device only.
