+I ([surge919](https://github.com/surge919)) successfully tied in [OwnTracks](http://owntracks.org/) to Home Assistant and [SmartThings](https://www.smartthings.com/) while using authentication for external access. The MQTT bridge doesn't support authentication so I set up 2 MQTT instances.
+ 
+Here are the steps I performed. Hopefully it saves someone else some time.
+ 
+It seems to be working pretty well but if anyone sees something incorrect in my configuration, please let me know. This is my first real interaction with MQTT.
+ 
+Here's a summary of my setup:
+ 
+Two Docker instances for MQTT
+
+- 1 for internal use (the MQTT bridge for SmartThings - no authentication)
+- 1 for external use (for OwnTracks - with authentication)
+ 
+All Docker configuration files are on my NAS so the Docker containers can be destroyed without affecting my actual configuration files.
+ 
+#### Docker setup for the mosquitto internal instance. No authentication for use with the MQTT bridge.
+
+```bash
+$ docker run -ti -p 1883:1883  \
+    -v /volume1/data/mosquitto-int/config:/mqtt/config:ro \
+    -v /volume1/data/mosquitto-int/log:/mqtt/log \
+    -v /volume1/data/mosquitto-int/data/:/mqtt/data/ \
+    --name mosquitto-int -d toke/mosquitto
+```
+
+#### Docker setup for the mosquitto external instance. With authentication for use with Owntracks.
+
+```bash
+$ docker run -ti -p 1884:1883  \
+    -v /volume1/data/mosquitto-ext/config:/mqtt/config:ro \
+    -v /volume1/data/mosquitto-ext/log:/mqtt/log \
+    -v /volume1/data/mosquitto-ext/data/:/mqtt/data/ \
+    -v /volume1/data/mosquitto-ext/etc:/etc/mosquitto \
+    --name mosquitto-ext -d toke/mosquitto
+```
+ 
+Here are the config files:
+
+`/volume1/data/mosquitto-int/config/mosquitto.conf`
+ 
+```bash
+connection mosquitto-ext
+persistence_file mosquitto.db
+try_private true
+address 10.0.0.20:1884
+start_type automatic
+sername test
+password test
+notifications true
+topic owntracks/# in
+log_type all
+log_dest file /mqtt/log/mqtt.log 
+log_facility 5
+```
+ 
+`/volume1/data/mosquitto-ext/config/mosquitto.conf`
+ 
+```bash
+connection mosquitto-int
+persistence_file mosquitto.db
+try_private true
+address 10.0.0.20:1883
+start_type automatic
+username test
+password test
+notifications true
+topic owntracks/# out
+log_type all
+log_dest file /mqtt/log/mqtt.log
+log_facility 5
+allow_anonymous false
+password_file /etc/mosquitto/pwfile
+```
+ 
+Create a password for `mosquitto-ext`
+ 
+```bash
+$ docker exec -it mosquitto-ext /bin/bash
+$ cd /etc/mosquitto/
+$ mosquitto_passwd -c /etc/mosquitto/pwfile <userID>
+```
+ 
+### OwnTracks settings for Android
+ 
+```bash
+Preferences / Connection / Mode - Private MQTT
+ 
+Fill out
+ Host
+ Identification
+ Security: TLS disabled
+```
