As the attack of online account hackers becomes more common, all users should ensure that they have taken all available security measures. One of the best ways to protect an online account is to use two-factor authentication (2FA).
Two-factor authentication provides additional security for login attempts by requiring users to provide additional information that only the account holder knows, such as a user ID. A code sent to the user's phone number or a code generated by two-factor authentication.
In iOS 15 and later, Apple added a built-in two-factor authentication feature that allows the iPhone to generate verification codes to provide additional security when signing into different online accounts.
If a website or app requires two-factor authentication (2FA), you can set a verification code for it without downloading a third-party app. After the setup is complete, the code generator generated by the iPhone automatically generates and fills in the verification code when you log in to the website or app, which makes it easier to use two-factor authentication on the iPhone.
How to set up a two-factor verification code generator on iPhone
To set up the iPhone-generated two-factor authentication code generator, you must first enable the use of identity verification apps on any website or app that supports this feature. It is easiest to use a computer to complete the activation process as some steps may require you to use a QR code displayed with the iPhone camera on the screen.
Some websites send verification codes in SMS because they use two-factor authentication by default. In this case, you must go to the security or privacy settings of the site to activate the verification application. For example: the Twitter account has an option to allow the use of identity verification applications. You can visit it by following these steps:
- Go to the Settings menu and then select Security and Account Access
- Select (Secure) and click on the (Two-Factor Authentication) option.
- Enable the identity verification application options
After activating the identity verification application in an account or application, the system will prompt you to enter a key or use the phone's camera to scan the QR code in the device.
If the input settings button, please follow the steps:
- Turn via iPhone settings (Settings)
- Click on the password option and select an app or service account from the list.
- Click the Setup verification code option, and then click Enter Setup key on the pop-up menu to enter the key.
- A verification code will be displayed on your mobile phone, copy it and go back to the website where you will get the main settings and enter the verification code to activate two-factor authentication.
If you are trying to protect your account website with a QR code, please open the iPhone camera app and point the camera lens at your computer screen to scan the QR code.
After scanning the code, click on the “Add verification code to password” option. You will be automatically redirected to (Set) and then to (Password). You may have to manually select the correct account to add the verification code. Your iPhone automatically generates a valid 30-second verification code that you can add to the website.
How to use the built-in iPhone-in-iPhone two-factor verification code generator
In the future, when you log into a website or service activated by a two-factor authentication application, the system will ask you to enter a verification code. Your iPhone generates a verification code that is valid for 30 seconds and uses a built-in two-factor authentication code generator. You just have to click on the icon to enter the fields it provides.
