SMS two-factor authentication is insecure; use alternatives

A million two-factor authentication codes sent via SMS were routed through a controversial third-party company, raising concerns about the security of this authentication method. This exposes the vulnerability of SMS-based security. The company, Fink Telecom Services, has a history of working with government spy agencies, according to reports. Major tech companies like Google, Meta, and Amazon, along with banks and other services, used Fink for SMS authentication, potentially exposing user data. Experts recommend using authenticator apps or physical security keys instead of SMS for two-factor authentication, as SMS lacks proper encryption. This is because SMS codes are more vulnerable to interception.
