Using SMS as an additional means to authenticate your password is better than nothing, but it's not the most reliable. Tom Merritt lists five reasons why SMS should not be used for MFA.

cPanel, a provider of popular administrative tools to manage web hosting, has patched a security vulnerability that could have allowed remote attackers with access to valid credentials to bypass two-factor authentication protection on an account. cPanel and WHM offers a Linux-based control panel for users to handle website and server management, including tasks such as adding sub-domains and performing system and control panel maintenance.

Microsoft last week released an out-of-band update for Windows to address authentication issues related to a recently patched Kerberos vulnerability.
