GitHub user saidiraja closed the discussion with a comment: Simplify QuickStart
for Airflow 3 standalone mode
Hi, I recently went through the same setup process with Airflow 3.x and had
similar confusion, especially regarding authentication and initialization.
A few clarifications that might help:
1. **Username and Password**
In Airflow 3.x, credentials are no longer "admin/admin".
When you run:
```bash
airflow standalone
```
Airflow automatically generates the admin password and stores it in:
```
${AIRFLOW_HOME}/simple_auth_manager_passwords.json.generated
```
You can retrieve it using:
```bash
cat ~/airflow/simple_auth_manager_passwords.json.generated
```
2. **Database initialization**
The command:
```bash
airflow db migrate
```
should be run **before starting Airflow**, but it is also automatically handled
when using `airflow standalone`, so you usually don’t need to run it manually.
3. **DAG detection**
Yes, Airflow scans for new DAGs periodically (by default every ~5 minutes),
so newly added DAGs may not appear immediately.
4. **General feedback**
I agree that the current documentation focuses more on concepts rather than
a clear step-by-step beginner setup. A simplified quick-start guide could
really improve the onboarding experience.
Thanks for sharing your notes — they are very helpful for beginners!
