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