Why this feels so hard
Online safety is rarely only about you.
Maybe you are worried about your own accounts. Maybe you are trying to help a parent, partner, or someone else you love. Either way, checking every message, account, and security headline yourself is not a realistic plan.
You do not need another reason to worry. You need a clear place to begin.
Risks show up everywhere
Scams can reach you through email, text messages, phone calls, social media, and online accounts.
Protection should not feel like panic
Online safety should help people feel more confident, not embarrassed, overwhelmed, or controlled.
You need answers you can actually use
Technical warnings are not helpful if no one explains what they mean or what to do next.
A simple first step
Find out whether your information may already be circulating online.
Step 1: Enter your email address
Use the email address you rely on for shopping, banking, social media, or everyday communication.
Step 2: Review the breach result
See whether the address has appeared in known data breaches and understand why it matters.
Step 3: Follow the next steps
