+Run every incoming message through `bwb.parse()` since it's inexpensive. This will decrypt and remove base58 encoding.
+
+Once decoded, send it through `bwb.check_auth()` which will return `True` or `False` if the code is valid.
 
 Example:
 
 ```text
+text = bwb.parse(text)
 if text.startswith('!'):
     ...
+elif text.startswith('000000'):
+    text = text[6:]
+elif bwb.check_auth(text):
+    authed = True
+    text = text[6:]
 else:
-    authed, text = bwb.parse(text)
-    if not text: return
+    return
 ```
 
 Use `bwb.wrap()` to auth and encode outgoing commands.
