Staying Safe Online The internet helps us to learn, work, and stay in touch with friends, but we must use it safely. Here are some important tips: Keep your passwords private and strong. Do not open attachments or links from unknown people. Check for the padlock symbol or https:// before entering personal details. Think carefully before you share information or pictures online. If you see something worrying, speak to your tutor or a trusted adult. Stay alert and stay safe when using the internet.
