In this guide, let us know how to use iCloud keychain two-factor authentication on an iPhone. Keychain is the native password management system by Apple. All across the Apple devices that you use, the iCloud keychain helps in storing passwords and credit card information securely. Passwords that you use for visiting various social media apps or accessing various websites are all stored in the keychain.

Now, to keep the passwords more secure iCloud keychain supports two-factor authentication. This you can jointly set up using the iCloud keychain setting and the corresponding app or website that supports the 2FA mechanism.

Also, the steps that I have described here are based on the all-new iOS 16. You may upgrade your iPhone to iOS 16. Otherwise, if you are still on iOS 15, you do get the support of setting up the iCloud keychain two-factor authentication. The steps are pretty much the same regardless of whether you are on iOS 15 or iOS 16.

When you do not have any access to use the two-factor authentication method, you can use this backup code to access your Twitter account. Keep in mind that this backup code can be used only once. In case you forget the code or use it once, you can generate a new backup code via the Twitter app.

For any other social media app, such as Snapchat or Instagram, you can easily use the iCloud keychain to set up two-factor authentication on your iPhone. The steps are pretty much the same as above. All the major apps and websites have an option to secure your access credentials by using the 2FA mechanism.
