Save Passwords in secrets

We sould not keep secrets in configuration files because they might leak e.g. when they are stored in a public repo.

Home Assistant has a secrets file which can store the secrets that can be referenced by Home Assistant.

Save MQTT user and password

Open the secrets.yaml file and the following with your credentials

mqtt_user: myuser
mqtt_password: mypassword

Any file that needs this password can not reference the name in secrets.yaml.

mqtt:
  user: !secret mqtt_user
  password: mqtt_password
