Securing iCloud Mail With Two-Factor Authentication

Keep your Apple email and other accounts safe

Apple's cloud storage system, iCloud, includes a free web-based email account you can access from any Mac, Windows, or iOS device via the iCloud website or the Mail app. Two-factor authentication is a great way to protect your iCloud Mail account from theft, hacking, and other misuses by unauthorized parties.

Here's how to enable two-factor authentication for your iCloud Mail account as well as any other programs associated with your Apple ID.

We'll look at setting up two-factor authentication for your iCloud email from a Mac, iOS device, and from a web browser.

Turn on Two-Factor Authentication for iCloud Mail

Two-factor authentication adds an additional barrier between whoever's logging in and the account by requiring authentication in two separate ways, such as your computer and phone. This is far more secure than a password alone.

If you don't already have one, you'll first need to set up an email address before you can use Mail on and set up two-factor authentication.
