Always allow ADB on Android?

Question

Is it possible for me to set an Android Device to automatically authorize adb from any computer? I know this this is a bad idea in terms of security, but I need if it's possible. Is there a list deep in the Android internals with the RSA fingerprints?

Answer 1

No, for security you cannot automatically authorize any future device.

The best way is to check the box to save the RSA key when you authorize a device so that it will always be authorized on that particular computer.

Answer 2

In userdebug or eng builds you can disable adb authorization with ro.adb.secure=0. Or if your device is rooted you could just replace the adbd with a custom modified insecure version.

Alternatively, if by any computer you just mean a few computers in your immediate vicinity - it might be easier to make all these systems to use the same RSA key. Then saving that key on the device would make all these systems authorized at once.
