Apple on Thursday updated its security procedures by adding two-step verification to both iMessage and FaceTime. This added step is meant to prevent someone from accessing your account, even if they know your password.

Two step verification requires that you verify your account to do a number of things, including:

• Sign in to My Apple ID to manage your account
• Sign in to iCloud on a new device or at iCloud.com
• Make an iTunes, iBooks, or App Store purchase from a new device
• Get Apple ID related support from Apple

Apple posted “Frequently asked questions about two-step verification for Apple ID” and “Using app-specific passwords” if you have any questions.
