An urgent message is not proof of authority. Pause before using its link or attachment. Check through a trusted route you already know, such as the official app or an established contact. A familiar display name alone is not proof of who sent it. Ask a trusted adult for help.
Worked example
A message claims your project will vanish unless you send a sign-in code. Do not send the code or use the message link. Ask a trusted adult and check the service through a known route.
The Invented Project Warning
A fictional message displays the name Project Coach and says: Send your sign-in code now or lose your project. It also contains an unexpected attachment. You were not signing in or expecting a file. An established school help contact is available separately. This is a reading exercise: there is no real link, attachment, code or account to test.
