Does mobian use a root account and password?

[parry]

ryo, thanks for tip about password, this is interesting.

I am wondering if I change the password from a numeric pin if I will have trouble unlocking the phone when presented with the number pad? -or will this still be the old numeric pin, independent of the new alphanumeric password? -Thanks

If you mean changing for the Mobian user, then yes.
You will be locked out from the GUI, so I do hope you have SSH enabled before you even try this out, or you'll need to re-flash your phone as your only way out.
You must change it to a password consisting of numbers only in order to be able to unlock the screen.

If you mean changing for the root user, then that will have no meaning regarding ability of logging into your phone.

For me the question is how to change the default pin.  The only place I can find to do that through the UI is under Users (in Mobian). However as much as I can change the 1st entry with a new password,  the system wont allow me to enter a confirming string. I understand that I can change the pin through the comand line using passwd, but why can't I change the pin through the UI ?  In fact changing the password with passwd does not change the login pin.  This is rather frustrating.  And inane
Thanks for any replies
