passwd, netkey – change or verify user password|
passwd [ username[@domain] ]
Passwd changes the invoker's Plan 9 password and/or APOP secret.
The Plan 9 password is used to login to a terminal while the APOP
secret is used for a number of external services: POP3, IMAP,
and VPN access. The optional argument specifies the user name
and authentication domain to use if different than the one
associated with the machine passwd is run on.

Now that cpu connections are always encrypted, the only good reason
to require that these commands be run only on terminals is concern
that the CPU server might be subverted.|
