PASSWD(1) PASSWD(1) NAME passwd - change user password SYNOPSIS auth/passwd [ -u user ] [ -s signer ] [ keyfile ] DESCRIPTION Passwd changes the secret shared between the invoker and the authentication server signer (default: $SIGNER). The signer must offer the keysrv(4) service. The secret is associated with a remote user name that need not be the same as the name of the invoking user on the local system. That remote user name is specified by a cer- tificate signed by signer, and obtained from keyfile. Keyfile identifies a file containing a certificate (default: `default'). If keyfile is not an absolute pathname, the file used will be /usr/user/keyring/keyfile. User by default is the invoking user's name (read from /dev/user), but the -u option can name another. Passwd connects to the signer, authenticating using the cer- tificate in keyfile, and checks that the user in the certi- ficate is registered there with an existing secret. Passwd then prompts for the (remote) user's old secret, to double- check identity, then prompts for a new one, which must be confirmed. Secrets must be at least eight characters long. Try to make them hard to guess.
