You should get prompted to accept an RSA key, which will mean that your computer is authorised.

Debugging Bypass A vulnerability found in Android 4.2.2-4.4.2 allowed attackers to bypass Android’s secure USB debugging, this allowed attackers to access adb prior to unlocking the device. SoftwareAndroidAffected VersionsAndroid 4.2.2-4.4.2CVE ReferenceAuthorsHenry Hoggard, MWR Labs (https://labs.mwrinfosecurity.com)SeverityMediumVendorGoogleVendor ResponseFixed in Android 4.4.3Description: Android Developer Bridge (adb) is a command line tool that allows users to communicate with and debug the device. It gives users permissions to access many areas of the device, including the ability to manage apps, access device logs, read device input, take backups and execute OS commands. In Android 4.2.2, Google implemented Secure USB Debugging, aimed to prevent adb from being connected to malicious computers. The user has to authorize a computer before it can connect with adb. The idea is that users can only authorize a computer after entering the password and unlocking the device. The bug detailed is only exploitable when adb is enabled on the device. Impact: If adb is enabled on the device, attackers with physical access to a device can bypass Android’s secure USB debugging protection. This allows attackers to gain adb access to the device, which would allow them to: • Install/uninstall applications • Bypass the lock screen • Access a high privilege shell on the device • Steal data from applications and settings on the device Cause: The adb authorize host confirmation dialog is displayed prior to unlocking the device on the emergency dialer and lock screen camera. This allows attackers with physical access to authorize their computer and connect with adb. Interim Workaround: If you are running a vulnerable version of Android, it is recommended to disable ADB to prevent this attack. Solution: Android 4.4.3 prevents the adb authorization confirmation dialog from being opened in the emergency dialer and lock screen camera prior to unlocking the device. Users can now only authorize a computer with ADB after the lock screen stage is passed. Therefore it is recommended that a strong device password is used. Technical details: The intended design of secure USB debugging, is that the user needs to be unlock the device to be able to authorize new adb hosts. If the user attempts to use adb while still at the Android lock screen, it will throw the following error: error: d
