+title: "Reauth and reconfigure flows need to be linked to a config entry"
+---
+
+Starting a reauth or a reconfigure flow without a link to the config entry has been deprecated, and will start failing in 2025.12.
+
+Custom integrations should be updated to trigger the reauth flow using the `entry.async_start_reauth(hass)` helper.
+```python
+    async def async_press(self) -> None:
+        """Handle the button press."""
+        try:
+            await self.device.press_button()
+        except DevicePasswordProtected as ex:
+            self.entry.async_start_reauth(self.hass)
+```
+
+Old incorrect code:
+```python
+    async def async_press(self) -> None:
+        """Handle the button press."""
+        try:
+            await self.device.press_button()
+        except DevicePasswordProtected as ex:
+            # old incorrect code:
+            self.hass.async_create_task(
+                hass.config_entries.flow.async_init(DOMAIN, context={"source": SOURCE_REAUTH}
+            )
+    )
+```
+
+Custom integrations can also raise a `ConfigEntryAuthFailed` exception during the initialization phase, or within the update method of a data update coordinator.
+
+```python
+async def async_setup_entry(hass: HomeAssistant, entry: ConfigEntry) -> bool:
+    """Set up integration from a config entry."""
+    username = entry.data[CONF_USERNAME]
+    password = entry.data[CONF_PASSWORD]
+
+    if not _credentials_valid(username, password):
+        raise ConfigEntryAuthFailed()
+```
+
+Starting a reconfigure flow is only done by the frontend and custom integrations should not need to change anything for these flows.
+
+More details can be found in the [reconfigure](/docs/config_entries_config_flow_handler#reconfigure) and [reauthentication](/docs/config_entries_config_flow_handler#reauthentication) documentation.
