How To Enable Two-Factor Authentication (2FA) On Paypal, WhatsApp, Microsoft, Apple, Facebook, Twitter & Instagram In 2021
Two-factor authentication (2FA) also known as two-step verification or multifactor authentication whih is widely used to add a layer of security to your online accounts.
The most common form of two-factor authentication when logging into an account is the process of entering your password and then receiving a code via text on your phone that you then need to enter. The second layer in two-factor authentication means a hacker or other nefarious individual would need to steal your password along with your phone in order to access your account.
How Does The Second Factor Work?
After you enter your password — the first authentication factor — the second factor usually arrives by SMS. That is, you’ll get a text with a numerical code that you’ll then need to enter to log into your account. Unlike a PIN code for a debit card, a 2FA code is used only one time; each time you log into that account, you’ll be sent a new code.
Alternatively, you can use a dedicated authentication app to receive codes instead of having them texted to you. Popular authentication apps are Google Authenticator, Authy and DuoMobile.
On the main Summary page, click the gear icon and find the Security tab. Look for the section called “2-step verification” and click on the Set Up link. You’ll get a choice to have a code texted to you or use an authenticator app.
Open up WhatsApp, and find the Settings menu under the upper-right hamburger icon. Look under “Account” > “Two-step verification” > “Enable.” The app will ask you to enter a six-digit PIN to use as verification and optionally add an email address in case you forget your PIN.
Log in to your Microsoft account and find the “Security settings” menu (there are several ways to get there; click on the link for the easiest). Look for the “Two-step verification” section and click on the setup link. You’ll be walked through the steps needed to use either the Microsoft Authenticator app or use a different authentication app. You’ll also be able to create passwords for apps that don’t accept 2FA.
Two-factor authentication is an extra layer of security for your Apple ID designed to ensure that you’re the only person who can access your account, even if someone knows your password.
