THE SHORT VERSION
Two-factor authentication adds another check when you sign in. Turn it on through your account’s security settings, and never give a caller your verification code.
A familiar situation
You sign in to your email and the service asks for another check. It might be a code, an authenticator app, or a security key. When you started that sign-in yourself, the extra step can be part of protecting your account.
1. Understand the extra check
Two-factor authentication uses a second way to confirm it is you. A stolen password alone may then be insufficient to enter your account. It improves protection, but it does not make an account impossible to compromise.
2. Start with an account you use often
Open the official app or website and find its security settings. Look for two-factor authentication, two-step verification, or multi-factor authentication. The available methods vary. Follow the provider’s instructions and review its recovery options before you finish.
3. Keep codes to yourself
Enter a verification code only in the legitimate sign-in process you initiated. Do not read it to an unexpected caller or send it in response to a message. An unexpected code is a reason to check your account directly, not approve an unfamiliar request.
One thing to try today
Set aside an unhurried moment to find the security settings for your email account. Ask for guidance if you need it, while keeping passwords and codes private.
