+.TH PASSWD 1
+.SH NAME
+passwd \- change user password
+.SH SYNOPSIS
+.B auth/passwd
+[
+.BI -u " user"
+] [
+.BI -s " signer"
+] [
+.I keyfile
+]
+.SH DESCRIPTION
+.I Passwd
+changes the secret shared between the invoker
+and the authentication server
+.I signer
+(default:
+.BR $SIGNER ).
+The
+.I signer
+must offer the
+.IR keysrv (4)
+service.
+.PP
+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 certificate signed by
+.IR signer ,
+and obtained from
+.IR keyfile .
+.I Keyfile
+identifies a file containing a certificate (default:
+.LR default ).
+If
+.I keyfile
+is not an absolute pathname,
+the file used will be
+.BI /usr/ user /keyring/ keyfile.
+.I User
+by default is the invoking user's name (read from
+.BR /dev/user ),
+but the
+.B -u
+option can name another.
+.PP
+.I Passwd
+connects to the
+.IR signer ,
+authenticating using the certificate in
+.IR keyfile ,
+and checks that the user in the certificate
+is registered there with an existing secret.
+.I Passwd
+then prompts for the (remote) user's old secret, to double-check identity, then prompts for a new one, which must be confirmed.
+.PP
+Secrets must be at least eight characters long.
+Try to make them hard to guess.
