2-Step Verification helps protect a user's account from unauthorized access should someone manage to obtain their password. Even if a password is cracked, guessed, or otherwise stolen, an attacker can't sign in without access to the user's additional verification. This verification can be in the form of codes which only the user can obtain via their own mobile phone, or via an encrypted signature contained on a security key.
2-Step Verification should always be enabled and enforced for all Super Administrator, VIP, sensitive access accounts, and all user accounts. http://www.livetechnicians.co
