I used the mosquitto_passwd command to create a password file.
mosquitto_passwd /etc/mosquitto/passwd admin I added the path to my password file in mosquitto.conf:
password_file /etc/mosquitto/passwd But when i subscribe or publish it doesn't require username/password?
mosquitto_sub -t '#' -d Client mosqsub/19032-Dell sending CONNECT Client mosqsub/19032-Dell received CONNACK Client mosqsub/19032-Dell sending SUBSCRIBE (Mid: 1, Topic: #, QoS: 0) Client mosqsub/19032-Dell received SUBACK Subscribed (mid: 1): 0 What did I miss?

The default configuration file is called mosquitto. conf and it is used by the mosquitto broker when started as a Linux daemon or Windows service. You will find the mosquitto. conf file in the /etc/mosquitto directory on Linux, and in the c:\mosquitto\ directory on Windows.
Client Authentication There are three ways that a Mosquitto broker can verify the identity of an MQTT client: Client ids. Usernames and passwords. Client Certificates.
File path is provided as first argument and username is provided as second argument. The -c option means that new password file will be created. Execute the following command and enter a password for the user: sudo mosquitto_passwd -c /etc/mosquitto/credentials myuser Now we need to modify Mosquitto configuration file.
This tutorial shows how to setup username and password authentication for Mosquitto broker on Raspberry Pi. We can create the password file using mosquitto_passwd tool. File path is provided as first argument and username is provided as second argument. The -c option means that new password file will be created.
In Mosquitto 2.0 and up, you must choose your authentication options explicitly before clients can connect. In earlier versions the default is to allow clients to connect without authentication. There are three choices for authentication: password files, authentication plugins, and unauthorised/anonymous access.
To configure the Mosquitto broker you will need to: Edit the mosquitto.conf file to force password use. To create a password file you need to use the mosquitto_passwd utility that comes with the client tools when installing the mosquitto broker. There are several ways of doing this:
By default, Mosquitto will still allow anonymous connections, i.e. connections where no username/password is provided. In addition to the password_file entry, you also need:
allow_anonymous false after modify "allow_anonymous false" in /etc/mosquitto/mosquitto.conf, user without password still can pub and sub
