- Fraud
- Tricking someone out of money or information by lying to them. A "scam" is fraud dressed up to look real.
- Identity theft
- When someone steals your personal details (name, birthday, Social Security number, passwords) and pretends to be you — usually to spend money or open accounts in your name.
- Phishing
- A fake message that pretends to be someone you trust (a bank, a company, a friend) to get you to click a bad link, log in on a fake page, or hand over private information.
- Smishing
- Phishing that arrives as a text message (SMS). The same trick, delivered to your phone.
- Vishing
- Phishing done by voice — a phone call from a fake "representative" trying to pressure you into sharing information or a code.
- Spoofing
- Faking the "from" part so a scam looks like it comes from a real person, company, or phone number. The name on the screen is not proof it is real.
- Personally identifiable information (PII)
- The pieces of information that can identify you: full name, birthday, address, phone number, Social Security number, account logins. Guard these — they are the raw material for identity theft.
- Data breach
- When a company gets hacked and the personal information it stored about you leaks out to criminals. It is not your fault, but it puts your data at risk.
- Two-factor authentication (2FA)
- A second lock on an account. Even if someone steals your password, they still need a one-time code (usually from your phone or an app) to get in. Turn it on for your email first.
- Password manager
- An app that creates and remembers a long, random, different password for every account, all locked behind one master password. It is how people actually use a unique password everywhere.
- Strong & unique password
- Strong means long and hard to guess (a passphrase like PurpleTaco$RunFast19 beats Zoe2010). Unique means a different one for each important account, so one leak cannot unlock the rest.
- Account takeover
- When a thief gets into one of your accounts, locks you out, and uses it — often to scam your friends by messaging them as "you.".
- Skimming
- Stealing card information with a hidden device attached to a card reader (like at a gas pump or ATM), so a thief copies your card without touching it.
- Malware
- Harmful software (from a bad link, attachment, or download) that can spy on you, steal passwords, or lock your device. "Ransomware" is malware that locks your files until you pay.
- Credit freeze
- Locking your credit file so no one can open new credit (a card or loan) in your name. It is free, does not hurt your credit score, and you unfreeze it yourself when you want new credit.
- Red flag
- A warning sign that a message or deal is a scam: urgency, "too good to be true," a demand for gift cards or crypto, secrecy, or an unexpected link or request for a code. When you spot one: stop and check with the real source another way.
