Modals excel at grabbing attention, making them effective for alerting and confirming destructive actions. When users are about to take steps that can't be undone—like deleting an account or important files—a modal serves as a final checkpoint. It isolates the decision, removing distractions and prompting users to pause and think.

The modal ensures the action is intentional, offering a last chance to cancel. It can also provide crucial information, such as the number of files to be deleted, so users understand the impact of their decision. By concentrating focus on the action at hand, modals minimize the risk of accidental or uninformed choices.
