mosquitto_passwd is a tool for managing password files for
the mosquitto MQTT broker.
Usernames must not contain ":". Passwords are stored in
a similar format to crypt(3).
-b
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.
-c
Create a new password file. If the file already exists,
it will be overwritten.
-D
Delete the specified user from the password file.
-U
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.
passwordfile
The password file to modify.
username
The username to add/update/delete.
password
The password to use when in batch mode.
Add a user to a new password file:
•mosquitto_passwd -c /etc/mosquitto/passwd
ral
Delete a user from a password file
•mosquitto_passwd -D /etc/mosquitto/passwd
