Now we have to authenticate on our maubot account that we created during the installation of maubot and that is accessible from its web-panel, but we will have to do it from the terminal with the mbc tool

Connect to the panel using the login and password provided earlier for install.sh

cat << EOF
Once the authentication is done, we will use the same tool again to connect to our user account (bot client) that we created on the Matrix homeserver, to generate a unique token code and a device-id in order to allow the bot to have full control over the client (It is important to do it from the terminal, not from a classic matrix client)

It is important that the user used has www-data rights, otherwise the authentication will not work.

Generate the token and the device ID by connecting with the matrix user.
