== Introduction ==

By default on buildroot there is no password for root user. It is not really secure and can be a problem for some packages like [[dropbear]].
This page explain how to set a default password on our board.

== On target ==

The straitforward way to set the root password is to login on the board then type :

<pre class="target">
# passwd
Changing password for root
New password:
Bad password: too short
Retype password:
Password for root changed by root
</pre>

If your password seems to be too simple for the system it will tell it, but the password is changed.

== On host ==

If we have a big production of APF* to flash with the same default password it will be really painfull to change it on each boards. The best way is then to change it under our rootfs.
