Short modules, each ending in a few questions that explain the answer. They are written for people who use computers and phones, not for specialists. Take them in order or pick the one you need.
01
Accounts and passwords
Why length beats complexity, why reuse is the real danger, and how a password manager fits into daily life.
02
Multi-factor authentication and passkeys
What the second factor adds, which kinds are stronger than others and why passkeys resist fake sites.
03
Recognising phishing and fake messages
The pressure patterns behind most fake messages, a calm routine for checking them and how to report one.
04
Updates and backups
Why patching closes known holes, how the 3-2-1 backup rule works and why an untested backup is only a hope.
05
Home network and Wi-Fi
The few settings on a home router that matter, what a VPN does and does not do, and how to treat smart devices.
06
Personal data and privacy
What counts as personal data, why collecting less is the strongest protection and how to share and delete with care.
07
Phones and apps
Screen lock, app sources and permissions, and what to do when a phone is lost or a SIM is taken over.
08
Securing a website you run
For site owners: HTTPS, security headers, forms, dependencies and the admin account, ordered by how much risk each removes.
09
When something goes wrong: the first hour
A calm sequence for the first hour of an incident: contain, preserve, tell the right people, then recover.
10
Families and children online
For parents and carers: ground rules, accounts and privacy settings, and how to talk when something frightening happens.
