Turn on two-factor
A second lock for your accounts, so a stolen password by itself isn't enough to get in.
Open the account's security settings
Sign in, open Settings, and look for Security, Two-step verification, or 2-step. Tap it, then choose to turn it on.
On your screen: The "Security" menu inside an account Choose how you'll get the code
A texted code is the easiest and perfectly good — start there. An authenticator app (a free app that makes the codes) is a step stronger if you're comfortable, but don't let it stop you. Either is a big upgrade.
On your screen: Choosing "Text message" as the second step Save your backup codes
The account gives you a short list of one-time backup codes in case you ever lose your phone. Print them or write them down and keep them with your master password. They're your spare key — don't skip this.
On your screen: The backup codes screen Do the ones that matter most first
Turn it on for your password manager, then email, bank, and your main social account. Those four protect the most. You can add the rest over time.
On your screen: A short checklist — password manager, email, bank, social Use your fingerprint or face, too
Turn on unlocking by fingerprint or face where it's offered. It never leaves your device — Apple, Google, and the apps never see it — and it makes signing in quick.
On your screen: The "Face ID" or "Fingerprint" switch turned on
If your screen looks a little different, don't worry. Companies word this differently — look for "Security," "Two-step," or "2-step verification." It's the same thing.
