A strong password is important, but passwords can still be stolen through phishing scams, data breaches, malware, or simply being reused on too many websites.
That’s where two-factor authentication (2FA) can make a huge difference.
With 2FA enabled, your password alone isn’t enough to access your account. When someone tries to sign in, the account asks for a second form of verification—such as a code from an authenticator app, a security key, a passkey, or sometimes a code sent to your phone.
That extra step can stop someone who has managed to steal your password from simply logging into your account. The U.S. Cybersecurity and Infrastructure Security Agency recommends multifactor authentication and says to use stronger, phishing-resistant methods when they’re available.
Where should you enable 2FA first?
I’d prioritize:
- Your email account — This is probably the most important. Your email is often used to reset the passwords for your other accounts.
- Banking and financial accounts
- Apple, Google, or Microsoft accounts
- Facebook and other social media
- Online shopping accounts that have saved payment information
- Cloud storage and other accounts containing personal information
Not all 2FA methods are equal.
If an account gives you a choice, an authenticator app, passkey, or security key generally provides stronger protection than receiving a code through a text message. SMS verification is still useful when it’s the best option an account provides, however.
One very important warning: Never give an unexpected verification code to someone who calls, emails, or messages you asking for it. A scammer who already has your password may try to convince you to give them the second factor they need to get into your account.
Ricmer Quick Take:
If an important account offers two-factor authentication, turn it on. That extra step when you occasionally sign in is worth the additional protection it provides.
And remember to save any backup/recovery codes the service gives you somewhere safe. Those codes can be extremely important if you lose or replace your phone.
