Apache Airflow 
Version : 1.10.12

Using HiveServer2Hook with default connection ( assuming that auth_mechanism: PLAIN, but also set as extra to double make sure ) 

The password edit test is left empty, but from hook/ connections code and logs it seems that is not:

from airflow.hooks.base_hook import BaseHook
connection = BaseHook.get_connection('hiveserver2_hadoop_one_umlaut_default')
print(connection.password)

[2020-10-05 09:04:35,396] {base_task_runner.py:113} INFO - Job 20527: Subtask UMLAUT_CT_MASTER_TABLE_LOAD [2020-10-05 09:04:35,395] {base_hook.py:89} INFO - Using connection to: id: hiveserver2_hadoop_one_umlaut_default.

def log_info(self):
        return ("id: {}. Host: {}, Port: {}, Schema: {}, "
                "Login: {}, Password: {}, extra: {}".
                format(self.conn_id,
                       self.host,
                       self.port,
                       self.schema,
                       self.login,
                       "XXXXXXXX" if self.password else None,
                       "XXXXXXXX" if self.extra_dejson else None))

from latest PyHive, looks like password is not None
