Changing User / Root Passwords on Qubes OS

I like to change my passwords a lot for both user & root. So in Dom0 what would be the commands to do this??
For root would it be…passwd (then I change password)

For user would it be… passwd user (then I change password)
Just asking as I have not done it yet and not really familiar with Dom0 yet

Thank you all

I believe there is no way to do it through a user interface. So I think that’s the way to change it.

Great I’ll give it a go!!
