mosquitto_passwd:tldr:bc376
The command mosquitto_passwd
is used to create and manage password files for Mosquitto, an open-source message broker that implements the MQTT (Message Queuing Telemetry Transport) protocol.
${path-to-password_file}
represents the path or location where the password file will be created or accessed. It could be an absolute path like /etc/mosquitto/passwd
or a relative path like ./passwd
(relative to the current working directory).
${username}
denotes the username for which you want to set or modify the password.
So, when you execute the command mosquitto_passwd ${path-to-password_file} ${username}
, it will prompt you to enter a password for the specified username and save it in the password file. If the username already exists in the password file, the old password will be replaced with the new one. If the file doesn't exist, it will be created.
After setting up the password file, you can use it for authentication with Mosquitto, requiring clients to provide the correct username and password when connecting to the MQTT broker.
