 When masking is enabled, Airflow will always mask the password field of every Connection that is accessed by a
 task.
 
-It will also mask the value of a Variable, rendered template dictionaries, XCom dictionaries or the
-field of a Connection's extra JSON blob if the name is in the list of known-sensitive fields (i.e. 'access_token',
-'api_key', 'apikey', 'authorization', 'passphrase', 'passwd', 'password', 'private_key', 'secret' or 'token').

+It will also mask the value of an Airflow Variable, rendered template dictionaries, XCom dictionaries or the field of a Connection's extra JSON blob if the
+Variable name or field name contains any of the known-sensitive keywords.
