Staying safe online at a glance
Staying safe online means a few strong habits that stop scams, protect your accounts and money, and keep your personal life private.
Like locking your home: a good lock (strong password), a second lock (two-step login), a peephole (checking who is at the door) and not handing your keys to strangers, however friendly they sound.

- Why do criminals target ordinary people online?
- Because it is cheap and easy to send millions of fake messages. If only a few people reply, criminals profit. You are not too unimportant to be targeted; everyone is.
- What do online scammers usually want?
- Money, your passwords and one-time codes, your personal details (to borrow in your name), or access to your phone or computer. Every scam aims at one of these.
- What is a scam, and how do most scams feel?
- A trick to get money or details. Most create a strong feeling: fear ("your account is blocked"), urgency ("within 2 hours"), greed ("you won a prize") or love. A strong push to act now is the warning sign.
- What is phishing?
- A fake email, text, or website that copies a real bank, delivery firm or government office to make you type your details or click a bad link. Text-message versions are often called smishing.
- What is an OTP, and why must you never share it?
- A one-time code sent by your bank or app to confirm it is really you. Anyone who has it can log in or pay as you. No real bank, company or official will ever ask you for it.
- What is a password manager?
- A secure app that creates a strong, different password for every website and remembers them all, so you only remember one main password. Phones and browsers include one.
- What is two-step login?
- After your password, a second check: a code from an app, a tap on your phone or a fingerprint. Even if someone steals your password, they still cannot get in.
- What is a passkey?
- A newer way to sign in using your phone's fingerprint, face or PIN instead of a password. There is nothing to type, so nothing to steal with a fake website.
- What is malware?
- Harmful software that sneaks onto a phone or computer to spy, steal passwords, show ads or lock your files for money. It often hides in fake apps, attachments and pirated downloads.
- What are privacy settings?
- Controls in each app that decide who sees your posts, photos, phone number and location. Setting them to friends only or private keeps strangers and scammers from learning about you.
- What do you need to start, and what will you be able to do?
- Just your phone or computer and the apps you already use. By the end you will spot scams fast, lock down your accounts and know exactly what to do if something goes wrong.
