Native Apple mobile apps like Mail, Contact, and Calendar use security tokens for authentication, which means the devices themselves don’t need to store your iCloud password. Two-factor authentication makes your devices more secure by requiring both a password and a six-digit verification code to access your accounts. ICloud provides several industry-standard security features, such as two-factor authentication (2FA), security tokens, and TLS 1.2 encryption. After choosing from a series of topics, you’ll eventually end up on a page where you can provide your phone number, and someone from Apple will call you back. If you have a problem that you need more direct help with, there is the Get Support section, which works in the same way as it does for any other Apple product or service.

ICloud has its own dedicated support page on the Apple website, which contains links to various help articles a page to check the iCloud system status and the Apple support community forums, where you can ask questions for other Apple users to answer. The web interface will run on any device that has a web browser, making it truly cross-platform. This is very similar to both Mac and iOS apps, although closer to what you see on an iPad. You can then send and receive emails from the Mail app on your Mac, iPhone, or iPad - or you can choose the web interface.
