TL;DR

Passwords

Weak or reused passwords are the most common way accounts get compromised. The fix is simple and takes about 20 minutes to set up.

Use a password manager

A password manager generates, stores, and autofills strong unique passwords for every account you have. You only need to remember one master password. This solves the root problem: people reuse passwords because remembering dozens of unique ones is impossible. With a manager, you don't have to.

Good free options: Bitwarden (open source, free tier is genuinely complete) and Apple Keychain or Google Password Manager if you're already in one of those ecosystems. Paid options like 1Password and Dashlane add features but aren't necessary for most people.

What makes a strong password

If you use a password manager, it generates these for you automatically. You never have to see them or remember them.

The one thing that matters most

If your email account is compromised, every other account is at risk, because password reset links go to your email. Make your email password unique, long, and protected by two-factor authentication. That account is the one to protect first.

Two-Factor Authentication (2FA)

Two-factor authentication adds a second verification step when logging in: usually a code sent to your phone or generated by an app. Even if someone gets your password, they can't access your account without also having your second factor.

Turn it on for every account that offers it, with priority on:

Types of 2FA, ranked by security

Authenticator App
Generates time-based codes on your phone using an app like Google Authenticator, Authy, or the authenticator built into your password manager. Not dependent on your phone number. The most secure common option.
SMS Text Code
A code sent to your phone via text. Better than nothing, but vulnerable to SIM swapping attacks where someone tricks your carrier into transferring your number. Avoid for high-value accounts if an authenticator app is available.
Backup Codes
One-time codes generated when you set up 2FA. Save these somewhere secure: a printed copy in a safe place or encrypted in your password manager. They're how you get back in if you lose access to your second factor.

Recognizing Scams and Phishing

Phishing is when someone impersonates a legitimate company or person to trick you into handing over credentials, money, or personal information. It's the most common way people get hacked, and it works because the messages often look completely real.

Signs something is a scam

When in doubt, go directly

If you get an email from your bank saying there's an issue with your account, don't click the link. Open a new browser tab and go directly to your bank's website. If there's actually a problem, you'll see it there. This one habit stops most phishing attempts cold.

What to guard carefully

Freeze your credit

A credit freeze prevents anyone from opening new credit accounts in your name, including you, until you lift it. It costs nothing, can be done online in minutes, and is the single most effective thing you can do to prevent identity theft. You can temporarily lift it when you actually need to apply for credit.

You need to freeze your credit at each of the three major bureaus separately:

Device and Network Security

Social Media and Your Digital Footprint

What you post publicly online can be seen by employers, landlords, and people you haven't met yet. A few habits worth building now:
