.SH NAME
myproxy-admin-change-pass \- change credential passphrase
.SH SYNOPSIS
.B myproxy-admin-change-pass
[
.I options
]
.SH DESCRIPTION
The
.B myproxy-admin-change-pass
command changes the passphrase used to encrypt a credential
in the MyProxy repository.
The command first prompts for the current passphrase for the
credential, then prompts twice for the new passphrase.
If an empty passphrase is given, the credential will not be
encrypted.
It accesses the repository directly and must be run on the machine
where the
.BR myproxy-server (8)
is installed from the account that owns the repository.

.TP
.B -h

.TP
.B -u

.TP
.BI -s " dir"
Specifies the location of the credential storage directory.
The directory must be accessible only by the user running the

process for security reasons.

$GLOBUS_LOCATION/var/myproxy
.TP

By default, the command prompts for a passphrase and reads the
passphrase from the active tty.  When running the command
non-interactively, there may be no associated tty.  Specifying this
option tells the command to read passphrases from standard input
without prompts or confirmation.
