Azure resource locks prevent accidental deletion or modification of resources. You can activate Read-only or Delete locks.
Activating resource lock is simple:
- Go to the resource
- Go to Settings -> Locks
- Click on + Add, enter Lock name and select Lock type
- Click Ok
You can implement resource locks at resource group level and subscription level. To delete a lock, go to the resource or resource group, go to Settings -> click on Locks select and delete the lock you need to remove.
