If you only do two things to protect your online life, do these:
- Use strong, unique passwords (or better: long passphrases)
- Turn on two-factor authentication (2FA) everywhere it’s offered
Why? Because passwords get stolen in data breaches, guessed by automated tools, or tricked out of people through phishing. 2FA adds a second “lock,” so a stolen password alone usually isn’t enough.
Why a password alone isn’t enough
According to the Federal Trade Commission, attackers commonly:
- trick people with phishing
- use stolen logins from data breaches
- try your password on other sites if you reuse it
- use software to guess passwords fast if sites don’t limit attempts
That’s why “strong password + 2FA” is a powerful combo.
What “strong password” really means in 2026
A strong password is mostly about length + uniqueness.
The NIST (the group behind widely used security guidelines) recommends focusing less on complicated rules and more on longer passwords. In fact, their guidance says services should not force weird “must include symbols” rules and should not force periodic password changes unless there’s evidence of compromise.
The easiest strong password: a passphrase
Think: 4–6 random words you can remember, like:

Better than: short “complex” passwords you forget and reuse.
The #1 rule: never reuse passwords
If one site gets breached and you reuse that password, attackers will try it on your email, banking, and social accounts next.
The easiest way to stay safe: use a password manager
A password manager helps you:
- generate unique passwords for every site
- store them safely so you don’t have to memorize 50 logins
- avoid “reusing the same one everywhere”
If you do use a password manager, make the master password a long passphrase, and put 2FA on the password manager too.
2FA explained like normal language
2FA means you log in with:
- something you know (password), and
- something you have (a code/app/key), or something you are (fingerprint/face)
With 2FA on, even if a hacker knows your password, they still usually can’t get in.
Which 2FA method is best?
The Federal Trade Commission lists common 2FA methods and explains the tradeoffs:
Best: Security key (strongest)
A security key is a small physical device (USB or NFC). The FTC calls it the strongest 2FA method because it doesn’t rely on codes that criminals can easily steal.
Great: Authenticator app
Apps generate codes (or push approvals) on your phone/tablet. FTC notes these are safer than text/email codes because they’re not vulnerable to SIM-swap attacks or email account takeovers.
Okay if it’s the only option: Text message or email code
Better than nothing, but FTC warns text codes can be intercepted through a SIM swap attack.
How to turn on 2FA fast (most sites)
- Open Account Settings
- Look for: Two-Factor Authentication, 2FA, Two-Step Verification, or Multi-Factor Authentication
- Choose your method (security key or authenticator app if available)
- Save your backup/recovery codes somewhere safe (offline is best)
FTC recommends starting with your most sensitive accounts: email, banking, payment apps, social media, and anything that can reset other passwords.
The two accounts you must secure first
1) Your email
Email is the reset button for most of your life online.
2) Your password manager (if you use one)
If someone gets into your password manager, they get everything.
Don’t get tricked: the #1 2FA scam
Never share your verification code with someone who contacted you first.
FTC explicitly warns that scammers try to trick people into handing over verification codes.
A realistic “best practice” setup
If you want a simple, strong setup most people can actually keep:
- Password manager with a long passphrase master password
- Unique password everywhere (no reusing)
- 2FA on important accounts, preferably:
- security key OR authenticator app
- text/email codes only when you have no other choice
Quick FAQ
Do I need to change my password every month?
Not usually. Security guidelines emphasize changing passwords when there’s evidence of compromise—not arbitrary forced changes.
Is “P@ssw0rd123!” strong?
It looks complex, but it’s common and predictable. A long, unique passphrase is usually safer and easier to remember.
What if I lose my phone/security key?
That’s why recovery codes matter. Save them somewhere safe before you need them.
