About this quiz: how exposed are you to an attack?

This free quiz measures your real exposure to scams, account theft and cyberattacks based on what you do, not what you know: passwords, two-factor authentication (MFA), SIM PIN, backups, app permissions and how you react to suspicious messages. At the end you get your exposure level and the three priority actions to reduce it.

The actions that most reduce anyone's digital exposure:

• Turn on two-factor authentication (MFA) on your main email: it is the master key to your other accounts; with MFA, a stolen password is not enough.
• One unique password per service, with a password manager: if one is stolen, the rest don't fall.
• A SIM PIN and phone lock: without a PIN, your line works in a thief's phone — and that's where your bank codes arrive.
• The two-places rule: your important files live in at least two places; the cloud counts as one.
• The doubt-and-verify protocol: for any message asking for money, data, codes or urgency, verify through another channel before acting.
