If you own an iPhone, you should be aware of an internal function that can help you safeguard your apps. Many iPhone users use third-party apps like Authy and Google Authenticator, to protect their data and information. These apps accomplish this goal of data protection by using a process known as two-factor authentication (2FA).
What is 2FA?
2FA requires a user to supply two formsof information in order to obtain access to an online account or computer system. According to Google research, this security method has been demonstrated to considerably reduce the likelihood of a threat actor obtaining access to someone's accounts, sometimes by half. iPhone now has its own built-in two-factor authentication, courtesy of Apple's iOS 15 upgrade from September of last year.
Apple describes 2FA on the iPhone as an extra layer of security that ensures that you're the only person who can access your account. This stands true even if someone knows your password. The functionality aids in the security of apps that hold sensitive data (such as banking or investing information). It can also assist you to avoid phishing and identity theft frauds.
How to enable 2FA?
Before you enable 2FA, it's vital to keep in mind that this 2FA solution won't work with every website or app.
- To get started, go to your iPhone's Settings and then to Passwords.
- To access your passwords, use Face or Touch ID, then tap on the account you wish to set up 2FA for.
- After that, select Set Up Verification Code.
- You'll see a menu with two choices: Scan QR Code and enter Setup Key. Choose one and then follow the instructions on the screen.
If you choose the QR code, you must look for it in the settings of that service/website to scan it. Only you can access your account via a trusted device or the web with this two-factor authentication from Apple. You'll need two pieces of information to sign in to your new device for the first time: your password and the six-digit verification code. This verification code is automatically shown on your trusted devices or emailed to your phone number. You confirm that you trust the new device by entering the code.
