### Tricks

You can indicate a **non-existent name a of database** in order to **create a new database without valid credentials** (**unauthenticated**):

![](<../../.gitbook/assets/image (258).png>)

Or if you know that for example a **mysql is running** and you know the **database name** and the **credentials** for that database, you can just access it:

![](<../../.gitbook/assets/image (259).png>)
