+# Settings Override
+
+### Browser token expiration
+
+The default browser token expiration is set to 5 hours. See this [ticket](https://github.com/wh1te909/tacticalrmm/issues/503) for reference.
+
+To change it, add the following code block to the end of `/rmm/api/tacticalrmm/tacticalrmm/local_settings.py`
+
+```python
+from datetime import timedelta
+
+REST_KNOX = {
+    "TOKEN_TTL": timedelta(days=30),
+    "AUTO_REFRESH": True,
+    "MIN_REFRESH_INTERVAL": 600,
+}
+```
+
+Change `(days=30)` to whatever you prefer. Then run `sudo systemctl restart rmm` for changes to take effect.
