Says to create app specific passwords and I’m afraid I’m gonna mess my new Appleid and password

An app-specific password is a unique password generated by Apple that allows you to securely access your iCloud Mail account when using third-party apps or services that don't support two-factor authentication. It provides an extra layer of security by creating a separate password specifically for that app or service, while keeping your main Apple ID password safe.

In the case of iCloud Mail, an app-specific password is required only if you intend to use the email service on an Android device. Android devices use different protocols and authentication methods compared to Apple's devices, which is why an app-specific password is necessary in this scenario. By generating an app-specific password, you can ensure that your iCloud Mail remains secure while accessing it through an Android device.

However, it's important to note that using an app-specific password does not affect or modify the existing passwords you use for any email accounts accessed through a web browser. If you regularly log in to your iCloud Mail account on a web browser, such as Safari or Chrome, you will still need to use the original password associated with that account.

The purpose of app-specific passwords is to provide a secure method of accessing specific services or apps on different platforms. This means that you can continue using your regular passwords for web-based access while utilizing app-specific passwords for applications on platforms that require them, like Android.

By implementing app-specific passwords, Apple ensures that even if a third-party app or service is compromised, your primary Apple ID password and iCloud Mail account remain protected. It's a security measure that allows you to grant limited access to specific apps without compromising the overall security of your Apple ID and iCloud Mail.

In summary, the use of an app-specific password does not alter or modify the Apple ID password.
