Digital security used to be a concern mostly for IT professionals — but today, everyone with a phone or a bank app is a target. Scammers, hackers, and data brokers are actively trying to get into your accounts, your money, and your personal information, and the tricks keep getting more convincing. This course is built for everyday people, not engineers: no jargon, no assumption you already know what a firewall is — just the practical habits that actually keep you safe. You start with the single biggest lever you have: passwords and authentication, learning how a password manager and two-factor authentication (or passkeys) stop the vast majority of account takeovers cold. From there you learn to recognize the scams that target real people every day — phishing emails and texts, fake delivery notifications, PIX and payment fraud, romance scams, and fake job offers — and the simple verification habits that unmask them before you lose a cent. Next you secure the device in your pocket: keeping it updated, controlling what apps can actually see and do, staying safe on public Wi-Fi, backing up what matters, and knowing exactly what to do if your phone is lost or stolen. You then turn to privacy — locking down social media, understanding how data brokers profile you, managing location sharing, and protecting kids online. Finally, you put it all together for money: spotting fake stores, keeping your card details safe, avoiding crypto scams, and knowing exactly what to do in the first hour after you realize you have been defrauded. By the end, you will handle your digital life with calm, practical confidence.
