Description of my issue

I installed the Mosquitto program. It works as expected with the username and password entered during installation. However, when I add a new user, it gives an authentication error. The password file contains a new user, but I think the hash algorithm used in the installation is not the same as the algorithm used by the ‘mosquitto_passwd’ command when adding a new user. If I edit the file and copy the password of the user created during the installation to the new user, the new user connects without any problems. What should I do to add a new user to the program in the standard way? Thanks in advance for your interest.

The password file contains a new user, but I think the hash algorithm used in the installation is not the same as the algorithm used by the ‘mosquitto_passwd’ command when adding a new user.

It literally uses mosquitto_passwd during install to hash the passwords.

How are you adding the new user?

From servers terminal ‘mosquitto_passwd -b /etc/mosquitto/passwd user password’

Does this return success? Is the file modified? Don’t you have to run with sudo? If the file is updated - is the password hashed or stored plaintext?

In the previous message I entered the command with sudo.

sudo mosquitto_passwd /etc/mosquitto/passwd user
Warning: File /etc/mosquitto/passwd owner is not root. Future versions will refuse to load this file.To fix this, use chown root /etc/mosquitto/passwd.Warning: File /etc/mosquitto/passwd group is not root. Future versions will refuse to load this file.
Password: *******
Password: *******

After entering this data, when I tried to log in, it failed. After restarting the service, it connected.
The problem was the need to restart the service.
Thank you for your help.
