ようになっているDesigned to work so that
ようになっている explains that a device, system, service, or procedure is designed so that a particular action or result occurs. It presents the operation as part of the existing setup.
An existing design, not merely a change
The important idea is that the behavior is built into an existing arrangement. The subject should therefore be something that can have a function or operating procedure: a machine, application, building, safety feature, service, or institution.
Showing both trigger and result
このドアは、非常ボタンを押すと自動的に開くようになっている。
This door is designed to open automatically when the emergency button is pressed.
Analyze非常ボタンを押すと gives the trigger, while 自動的に開く gives the built-in result.
Preventing, allowing, and automating
The verb before the expression changes according to what the design does.

Analyze入力した情報は、送信前に暗号化されるようになっている。

AnalyzeChange versus built-in design
ようになる ordinarily describes a change into a new ability or state. By contrast, the target form presents the current setup as designed to produce a certain operation. A person's newly acquired ability is therefore not, by itself, an example of the mechanism use taught here.
日本に来てから、納豆も食べられるようになった。
Since coming to Japan, I have become able to eat natto too.
AnalyzeThis is the neighboring change-of-ability use, not a designed system.
Former arrangements
Use the past ending when explaining how an earlier version of a system was configured. This describes the former arrangement rather than simply saying that an event happened once.
