iCloud for Windows 11.4
To improve the overall security and privacy of Mac users, one of the major features in the new update is iCloud for Windows 11.4. This feature allows users to access their files securely on either platform. In addition, whether on a Mac or a Windows PC, users can set up two-factor authentication for their iCloud accounts and store their passwords in an encrypted format.
Since all data is stored in Apple’s secure iCloud servers, user information is always encrypted and never sent to other devices for access or sharing. In addition, all synchronisation data (such as photos, contacts and calendar entries) remain secure and protected by Apple’s security protocols. For added protection, Apple also requires regular password changes for users who log in from a different location than previously used.
Using iCloud for Windows 11.4, users can check on up-to-date information from wherever they are located; documents that have been updated while away can be quickly accessed once they are back at home or work with no need to re authenticate the device used previously.
In addition, increased security changes have been added to better protect against phishing attacks, which have become increasingly common with social media platforms used on Mac and Windows computers worldwide. These safety features provide an additional layer of protection every time you log onto your computer or mobile device through your iCloud account with enhanced password guidelines and other improved authentication measures being utilised as well.
Apple Pay is a feature available to Mac users running the latest macOS Big Sur 11.4 update. With Apple Pay, users can use their Mac to make secure payments online, in stores, or within apps using their Apple ID and a connected card.
When making an online purchase with Apple Pay, the user’s credit card information provides an extra layer of protection coded using chip-enabled technology that displays as a set of random numbers to help keep customers safe while paying online. In addition, they can authorise a payment with biometric authentication such as Face ID or Touch ID depending on their device and system settings.
When making a payment in-store or within an app with Apple Pay users will tap their device against supported contactless readers like cards do. The transaction is completed securely requiring no signature at the point of purchase. The process takes only seconds to complete and can be done from any iOS or macOS device (iPhone or Mac computer) that supports the feature and is properly configured for payments.
