What is Two-Step Sign-In?
Two-step sign-in, or multi-factor authentication, requires users to provide two of the three possible types of authentication factors: something they know (like a password), something they have (like a smartphone), or something they are (like a fingerprint). This makes it much harder for hackers to access your accounts.
Which Accounts Should I Protect First?
You should start by securing accounts that hold sensitive information, like banking or email accounts. This is because if a hacker gains access to one of these accounts, they could potentially access other accounts that use the same login information. For example, if a hacker gets your banking password, they might also try the same password on your email account, where they could view your financial statements or even set up a fake banking account under your name.
Step-by-Step Guide for Setting Up Two-Step Sign-In
1. Choose a Service Provider: Most popular services like Google, Facebook, and Apple offer two-step sign-in. You can enable it through their settings.
2. Add a Backup Method: It's important to have an alternative method to receive the second factor, like a text message or a dedicated app. Choose one that you always have access to.
3. Set Up an App for the Second Factor: Apps like Google Authenticator or Authy can generate a code for the second step. This code changes every minute and can be used to log in.
4. Test the Setup: Try logging in with both your password and the second factor to ensure it works smoothly. This is important to avoid confusion when you actually need to use it.
5. Keep Your Second Factor Secure: Do not share the backup codes or the backup number with anyone. Keep them in a secure place, like a password manager, and update them regularly.
How to Use Two-Step Sign-In Safely
- Remember Your Second Factor: Always have your backup method handy, like a physical copy of your backup codes or the app to receive the second factor.
- Don’t Enable Two-Step Sign-In on Public Computers: If you use public computers, like at a library or coffee shop, don’t enable two-step sign-in. This could compromise your account.
- Regularly Update Your Second Factor: Change your backup codes and update your app regularly to keep your accounts secure.
What to Do This Week
This week, set up two-step sign-in on your primary email account and your banking account. Once you’ve set it up, test it by logging in from a different device. This way, you’ll be ready to use it in case you need to access your account from a different computer.
By following these steps, you'll be able to add an extra layer of security to your accounts, making them less vulnerable to unauthorized access.
Doing it once, properly
The lowest quote rarely stays the lowest. Work that skips the security basics tends to be redone from scratch later, and redoing it costs more than doing it properly once.
