Use Sign In With Apple for an easy and secure way to sign in to your apps and online accounts. Read below to learn more about this security feature.
Sign In With Apple is a tool that can help you improve your online security when you sign in to third-party apps and websites on your Apple devices with Apple ID . The feature works in any browser and supported app and is available on iOS, macOS, tvOS, and WatchOS. You can choose to use Sign In With Apple to verify your credentials instead of signing in with Facebook, Google , or creating a brand new account using your email address on an app or website.
Sign In With Apple is part of the tech giant's ongoing commitment to privacy. In recent years, Apple has added more privacy controls to iOS, including the ability to prevent apps from tracking you across websites and information that shows you what data apps are collecting before you download them.

Here's everything you need to know about how Sign In With Apple and how to use it. Plus, see how to control your iPhone's privacy settings in easy steps and some rules for strong passwords.
- When you open an app or website, if it supports Sign In With Apple, just tap Continue with Apple.
- Accept or deny any permissions requested by the application.
- Follow the onscreen instructions about Apple ID . You can choose to edit your name and make your email public or hidden. Select Continue.
- Enter your passcode when prompted. You can also use Face ID or Touch ID. If you don't have either, you can use your Apple ID password.
As long as you're signed in to your device, you'll be signed in to the app. To sign out, simply find the settings in the app or website and select Sign Out. You'll need to repeat the process if you want to sign in again.
How does Sign In With Apple work?
Sign In With Apple uses your Apple device to verify your credentials instead of using your social media account login details, which could leave you vulnerable to online tracking. With Hide My Email, Apple generates a random email address — you'll recognize it by the unique alphanumeric string followed by @privaterelay.appleid.com.
The random email address can only be used for a specific app. The app or website will use the generated email, but Apple will forward any correspondence to your real email, protecting your identity. You can reply to any email you want without revealing your personal email address. Apple also allows you to turn off email forwarding at any time.
Sign In With Apple says it won't use any of your information beyond what's needed to let you sign in and out of an account. The tool also uses two-factor authentication with Face ID or Touch ID. If you don't see the Sign in option, it means the app or website doesn't support the feature yet.

How can I find out which apps support this feature?
- Open the Settings on your iPhone, iPad, or iPod Touch and tap your name.
- Tap Passwords and Security.
- Select Apps Using Your Apple ID.
From there — if you used Sign in — you should see a list of apps. You can tap each app and see what settings you have set or change them, as well as read the app or website's privacy policy. You can also turn off email forwarding here, as well as stop using your Apple ID with the app.
Here's how you can do it on a Mac:
- Select the Apple menu.
- Open System Preferences.
- Click Edit.
Below you will find how to do it from a browser:
- Sign in to appleid.apple.com.
- Find the Security.

If you're using Hide My Email and need to make some changes, here's how on mobile:
- Open Settings.

- Tap Name, Phone Numbers, Email.
- Click Forward under Hide My Email.
- Select a new email address to use when forwarding.
The new address you enter will apply to all applications with which you use the Hide My Email.

Signing in with Apple is different from using Facebook or Google login. Sign In With Apple is only visually similar to the icons that allow you to use your Google or Facebook credentials. While signing in with Facebook or Google may seem easier, a lot of personal information is attached to these accounts, such as your nicknames, hometown, and birthday. This data may seem insignificant at first glance, but some of it is a major source of security risk to your bank account and other sensitive information.
Sign In With Apple also gives you more control over the permissions that apps and websites have access to. You can choose which apps should ask for your permission whenever they need your location data from Wi-Fi and Bluetooth. This is handy if you're trying out a new app or don't plan to use an app often, for example.
