Google has updated its security app for two-factor authentication to include the ability to sync passcodes across devices. Prior to this update the free Google Authenticator app lacked the capability for synchronization, meaning that users who lost their device also lost access to their two-factor authentication codes. However, Google announced on Monday that this limitation will no longer be an issue.
Thanks to policy changes at Twitter, SMS two-factor authentication (2FA) is no longer available for free. Users must have a subscription to Twitter Blue in order to use SMS for 2FA when securing their accounts. Twitter claims that requiring membership will reduce abuse of the platform by "bad actors". While SMS verification is a convenient and popular way to increase account security, it's not the most secure. Using an authentication app provides improved protection for your account.
This week Apple released two iOS updates delivering new features, bug fixes, and security enhancements. While iOS 16.4 was widely anticipated, the company also rolled out iOS 15.7.4 to ensure iOS 15 users are protected from the most recently discovered security threats. iPhone owners are strongly encouraged to update to the latest versions of iOS as soon as possible. Navigate to Settings -> General -> Software Update to start the process.
Twitter requires a paid subscription for Twitter Blue to use SMS two-factor authentication. While SMS or text messaging is a popular way to increase security, the new company policy is to reduce abuse by "bad actors" by demanding Twitter Blue membership for the service. This does not mean that 2FA cannot be used by those without a blue check mark on Twitter.
With the release of iOS 16.3 Apple now supports physical security keys. To level up your 2FA iPhone users will need two or more hardware keys. Apple does not produce its own security keys, however the company does maintain a list of recommended keys for iPhone, iPad, and Mac. FIDO-certified security keys are the way to go.
