Wi-Fi credentials security
If a Linux platform has no root password e.g. RaspberryPI, how secure is it to enter the Wi-Fi credentials as plain text into the 'interfaces' file?

That is not secure at all.There should always be a password prompt when accessing the root profile. Try to set one up if possible.
Passwords, or any type of security credentials transmitted in plain text will never be secured. The characters are not encrypted and can be easily stolen by a network sniffer. Always use strong wi-fi encryption.
How easy would it be for someone to gain access to the interfaces file and view the password?
Thanks.
Not that easy.
In my opinion, anyone who does not change the default or null passwords immediately is not a good administrator and probably should not have access to those resources in the first place.
I have never heard or noticed such a setting. On the devices I have used with embedded linux, I was never able to gain root access to my device. One of those devices was an HTC EVO (android). Looks like I have learned something new.
I'm new to embedded Linux.
How do I remove a null password or create a new password in the shell?
Thanks.
