🔧 Technical Details

Confirmation Protection Mechanism

MongoDB Lens provides protection measures for destructive operations. Here are the specific steps:

1. Request to delete a collection:

   "Drop the collection named test_collection"
   

2. Lens pops up a warning and generates a confirmation code:

   ⚠️ Warning: Potential dangerous operation ⚠️
   
   You have requested to delete the collection named 'test_collection'.
   
   This operation is irreversible and will permanently delete all data.
   
   Please enter the following confirmation code to continue:
   
   Confirmation code: 9876
   
   This code will expire in 5 minutes.
   

3. Enter the confirmation code:

   "9876"
   

4. Execute the operation and receive a success prompt:

   The collection 'test_collection' has been permanently deleted.
   

⚠️ Important Note

In a controlled environment, the confirmation mechanism can be bypassed through configuration.
