We've seen all login pages where you can sign in to third-party accounts using your Facebook, Google, or Twitter credentials. You save yourself the trouble of creating a new account and remembering more passwords. However, this can also become a privacy and security problem. For this reason, Apple has created the "Sign in with Apple" feature for iOS 13.
Signing up for Facebook or Google to sign in to other accounts is not bad by nature. Most large technology companies use open standards, such as OAuth 2.0 or OpenID Connect, which allow third-party websites to access only some of your personal information in order to authenticate you. But even that data can be used in ways you do not want.
The biggest single sign-on (SSO) problem is that your data (eg, your birthday, employment, college, and friends list) may be passed on to third parties, who in turn to sell the collected information to other companies for advertising purposes. In addition, they can continue to gather information while tracking you while using other apps and websites. If you search for local concert tickets on Google, the third party will probably know.
With all this information, these companies are creating an increasingly robust profile for you, which is already bad enough, but can be downright worrying to hackers into getting into one of your least secure accounts. Because your profiles are linked via SSO, hackers may be able to get a lot more information than they would otherwise, as they have access to more than one of their accounts. This brings us back to logging in to Apple.
What you need to know About signing in with Apple
Although Apple is similar to other SSOs, Apple takes some steps to protect your privacy. First, there are still technologies that are similar to OAuth 2.0 and OpenID Connect, so you know that they are at least as good as other SSOs. Second, it provides dual protection by logging in with the Touch ID or Face ID and performing two-factor authentication, which requires you to enter additional code that will be sent to you for login.
Third, Apple third-party services can not track you while you surf the Internet. Enter services like Google and Twitter. In this way they collect more information about you for marketing and promotional purposes. Apple prevents this, however. Apple also does not allow third-party services to store your user data.
And, last but not least, Apple accidentally generates an email address that allows you to sign in instead of giving them your personal email address for third-party apps and services, if desired. This anonymous e-mail can be used to forward messages to your personal e-mail, as Craigslist does. This means that you can immediately stop contacting third parties by simply deleting the temporary e-mail address. Also, marketers will not have your actual email address to harass you, which is always good.
As you can see, signing up with Apple protects what matters most to you, but it also provides you with a quick and easy way to do so. Sign up for apps and websites without remembering old credentials or new ones to enter.
To sign up for an application or website, you only need a few things:
- An Apple device with iOS 1
- An Apple ID with two enabled Factor Authentication
Additionally, you can use the "Sign in with Apple" feature in Safari and other web browsers, as well as on platforms like Android and Windows, but you still need an Apple device that has your Apple ID information logged on are.
You may also be wondering which services / websites / apps are already in use. Log in to Apple. There is no official list, but some of the big names are Kayak, Bird, WordPress, Fretello, Parcel, Lifecake and many more. If you do not see the Sign in to Apple button on your favorite app, do not fret – Apple needs all apps that support single sign-on to possibly sign up for Apple.
To use this new Apple service, you must first search for a third-party participating app or website. In this example, we use Quartz, the popular and award-winning mobile news app. As you can see on the following screenshots, Quartz has added the "Sign in with Apple" feature to its login page: Continue with Apple .
Tap this button to launch an Apple ID sign-in similar to the one you see when you download a new app or use Apple Pay. As you can see above, you're trying to create an account for this third-party app / website using your Apple ID. Below you will see your name and your e-mail address (s).
Now you can type (1) your name to change it, and (2) share your e-mail address, choose a different e-mail address, associated with your Apple ID, or completely hide your email address. To change your name just tap on your name and enter a new name. You can not leave this field blank, so you must enter something.
To hide your email address from a third-party app / site, tap Hide my email address. You can see where your emails are being directed (your primary Apple ID email) if that service decides to contact you. If you do not want to hide your emails, tap "Share my emails" and choose from multiple emails (if applicable).
