Lock down your iPhone and your online life

Thieves, scammers and snoops rarely "hack" an iPhone. They go after people, and the little shortcuts we all take. This guide closes those doors, one calm step at a time, with Cy beside you all the way.

It goes well beyond the basics:

• The phone in your hand: a passcode nobody can guess, Stolen Device Protection, locking down your Lock Screen and SIM, and updates that fix themselves.
• Your Apple Account: see who already has access, plan for the day you're locked out, and choose security keys, passwords and passkeys.
• Your online life: keep your email address private, stop being tracked, check who can see what, and lock down your main email account.
• Scams and the worst day: let your iPhone screen the scammers, learn the golden rules, and know exactly what to do if your phone is stolen.

Also included: a six-monthly security check-up to tick off, and a printable "If my iPhone goes missing" card to keep somewhere private at home.

Big, clear type, a picture for every step and the exact buttons to tap. Made for iOS 26 and iOS 27. Set aside an hour and a cup of tea.
