I just installed ubuntu touch latest devel on my nexus 7 2013. Everytime i open the terminal app it asks for a password. I am not talking for the root password that i read it is "ubuntu". Does anyone has a clue?
If you set a passcode or passphrase lock on your phone, that is also your user password that the Terminal (and also File Manager) will ask for.
This is a security precaution, since Terminal and File Manager have permission to access all your user data, you don't want somebody picking up your unlocked phone and doing evil things with your files.
