adb

Either install Android Studio, or platform-tools to get a standalone adb executable.

Enable USB debugging on your mobile phone:

• settings > info > version > tap build 7x

• settings > dev > enable USB debug

Verify adb key:

adb pubkey ~/.android/adbkey | awk '{print $1}' | openssl base64 -A -a -d | openssl md5 -c | awk '{ print $2 }' | tr a-z A-Z
