.SH "DESCRIPTION"
.PP
\fBmosquitto_passwd\fR
is a tool for managing password files for the mosquitto MQTT broker\&.
.PP
Usernames must not contain ":"\&. Passwords are stored in a similar format to
\fBcrypt\fR(3)\&.
.SH "OPTIONS"
.PP
\fB\-b\fR
.RS 4
Run in batch mode\&. This allows the password to be provided at the command line which can be convenient but should be used with care because the password will be visible on the command line and in command history\&.
.RE
.PP
\fB\-c\fR
.RS 4
Create a new password file\&. If the file already exists, it will be overwritten\&.
.RE
.PP
\fB\-D\fR
.RS 4
Delete the specified user from the password file\&.
.RE
.PP
\fB\-H\fR
.RS 4
Choose the hash to use\&. Can be one of
\fIsha512\-pbkdf2\fR
or
\fIsha512\fR\&. Defaults to
\fIsha512\-pbkdf2\fR\&. The
\fIsha512\fR
option is provided for creating password files for use with Mosquitto 1\&.6 and earlier\&.
.RE
.PP
\fB\-U\fR
.RS 4
This option can be used to upgrade/convert a password file with plain text passwords into one using hashed passwords\&. It will modify the specified file\&. It does not detect whether passwords are already hashed, so using it on a password file that already contains hashed passwords will generate new hashes based on the old hashes and render the password file unusable\&.
.RE
.PP
\fBpasswordfile\fR
.RS 4
The password file to modify\&.
.RE
.PP
\fBusername\fR
.RS 4
The username to add/update/delete\&.
.RE
.PP
\fBpassword\fR
.RS 4
The password to use when in batch mode\&.
.RE
.SH "EXIT STATUS"
.PP
mosquitto_sub returns zero on success, or non\-zero on error\&. If the connection is refused by the broker at the MQTT level, then the exit code is the CONNACK reason code\&. If another error occurs, the exit code is a libmosquitto return value\&.
