How to enable 2FA and secure your Apple ID and iCloud

Two factor authentication, or 2FA for short, is one of the best and most important ways to shore up your Apple ID and iCloud security. Here’s how to enable it.

With 2FA active on your your Apple ID, it’s extremely hard for a third party to access your account – even if they somehow know your password. This is why we always recommend users activate the feature when it is available and supplement it with a strong password and robust anti-virus service.

As the name suggests, two factor authentication requires you to provide two pieces of information when you want to sign in using a new device – your password and a verification code sent to a trusted device.
