Two-factor authentication is the single most effective thing most people can do for their accounts, and it takes about two minutes per account. The idea is simple: even if someone gets your password, they still cannot sign in without a second proof that it is you — usually a code from your phone or an app.

Here is how to turn it on for the three accounts that matter most: Google, Apple, and Facebook. Do them one at a time, and start with your email account, since password resets for everything else tend to go through it.

One note before you start: menu names can shift slightly between app versions, so if a label below looks a little different on your screen, you are almost certainly in the right place. And when any of these services offers you backup or recovery codes, save them somewhere you can find them if you lose your phone — that is the part people skip and later regret.

## Google: turn on 2-Step Verification

Google calls it 2-Step Verification, which is the same thing under a different name.

1. Open your Google Account at myaccount.google.com and sign in.
2. Select **Security** (in the left-hand menu on a computer, or the top menu on a phone).
3. Under "How you sign in to Google," select **2-Step Verification**, then **Get Started**. You may be asked to sign in again.
4. Pick a second step. Google offers prompts on your phone, an authenticator app, text-message codes, or a physical security key. An authenticator app is the strongest everyday option; text messages work but are easier to intercept.
5. Follow the prompts to verify, then select **Turn On**.
6. While you are on that page, set up a backup option too — backup codes are the simplest. Print them or write them down and keep them somewhere safe.

Once it is on, signing in from a new device will ask for your password plus that second step.

## Apple: turn on two-factor authentication for your Apple Account

For most Apple accounts this is already on by default, especially on newer devices. If yours is not, here is where to find it:

1. On your iPhone or iPad, open **Settings** and tap your name at the top.
2. Tap **Sign-In & Security**.
3. Tap **Two-Factor Authentication** and follow the onscreen instructions. You will add a trusted phone number, and Apple will send it a verification code to confirm.
4. On a Mac, the same setting lives under **System Settings**, then your name, then **Sign-In & Security**.

After that, signing in to your Apple Account on a new device will ask for your password plus a six-digit code, which appears automatically on your trusted devices or goes to your trusted phone number.

## Facebook: turn on two-factor authentication

Facebook moved this into its Accounts Center, so the path is a little longer than it used to be:

1. Tap or click your profile picture, then go to **Settings & privacy**, then **Settings**.
2. Select **Accounts Center**, then **Password and security**.
3. Choose **Two-factor authentication**, then select your Facebook account.
4. Pick a method: an authenticator app is recommended, but text-message codes and security keys are also offered. Follow the prompts to finish setup.
5. Save the recovery codes Facebook shows you. If you ever lose access to your second step, those codes are how you get back in.

## A few habits that make it stick

- **Use an authenticator app where you can.** It works without a phone signal and is harder to intercept than a text message.
- **Do not use the same second step everywhere if you can help it.** If your phone number is your only backup for every account, losing your number becomes a single point of failure.
- **Check it once.** After turning it on, sign out and sign back in somewhere to make sure the second step works the way you expect — better to find a problem now than when you actually need the account.

That is it. Three accounts, a few minutes each, and the most common way accounts get taken over — a stolen password alone — stops working.
