Closes: #51094 # Why Airflow does **not** currently support OAuth for SMTP. Microsoft is removing BasicAuth as capability from Exchange Online globally this September 2025 (Source: [Microsoft announcement](https://techcommunity.microsoft.com/blog/exchange/exchange-online-to-retire-basic-auth-for-client-submission-smtp-auth/4114750)). # How | **Area** | **Change** | |----------|------------| | **Core** | `send_email_smtp` / `send_mime_email` now accept `auth_type="oauth2"` and an optional `access_token`. | | **Provider** | `SmtpHook`, `SmtpNotifier`, and `EmailOperator` accept `auth_type`; the hook reads either `access_token` **or** `client_id` + `client_secret` from *Connection extra*. | | **UI** | Connection form exposes the new fields (`auth_type`, `access_token`, `client_id`, …). | | **Docs** | Updated **connections/smtp.rst**. | | **Tests** | New unit tests cover both Basic Auth and OAuth 2 paths. | # What ### Step 1 Use the [Goole Oauth Playground](https://developers.google.com/oauthplayground) to obtain an `access_token`. ### Step 2 Start Airflow locally with `breeze start-airflow` and add a connection: ```bash airflow connections add 'smtp_gmail_oauth2' \ --conn-type smtp \ --conn-host smtp.gmail.com \ --conn-port 587 \ --conn-login '[email protected]' \ --conn-extra '{ "from_email": "[email protected]", "auth_type": "oauth2", "access_token": "ya29.*****", "disable_ssl": "true" }' ``` ### Step 3 Tested by run this DAG ```python from airflow import DAG from airflow.operators.python import PythonOperator from airflow.providers.smtp.hooks.smtp import SmtpHook from datetime import datetime def gmail_oauth2_test(): with SmtpHook(smtp_conn_id="smtp_gmail_oauth2", auth_type="oauth2") as hook: hook.send_email_smtp( to="[email protected]", subject="[Airflow→Gmail] OAuth2 OK", html_content="<h3>Gmail XOAUTH2 works 🎉</h3>", ) with DAG( dag_id="test_gmail_oauth2", start_date=datetime(2025,7,1), schedule=None, catchup=False, ) as dag: PythonOperator(task_id="send_mail", python_callable=gmail_oauth2_test) ``` Or add in `airflow.cfg` ```console [smtp] smtp_host = smtp.gmail.com smtp_port = 587 smtp_starttls = True smtp_ssl = False ``` Then in a Python shell: ```python from airflow.utils.email import send_email_smtp send_email_smtp( to="[email protected]", subject="[Airflow utils] XOAUTH2 test", html_content="<h3>🎉 utils.send_email_smtp works</h3>", conn_id="smtp_gmail_oauth2", auth_type="oauth2", access_token="ya29.*****" ) ``` ### Step 4 Confirm the message arrived in mailbox. <img width="459" height="192" alt="截圖 2025-07-19 下午2 53 06" src="https://github.com/user-attachments/assets/4936f4df-6ff8-44b6-8077-ed5aded5e736"; /> -- This is an automated message from the Apache Git Service.
