FBI warns against using two-factor text authentication | Morning in America https://www.yahoo.com/news/fbi-warns-against-using-two-133502690.html "The FBI is warning Americans to stop relying on text messages for two-factor authentication in the wake of a major network hack that could expose unencrypted messages to cybercriminals. Earlier this month, the FBI urged cell phone users to use encrypted messaging apps, like Signal or WhatsApp, to ensure their communications stay hidden from an alleged Chinese cyberattack. The warning came after hackers, believed to be linked to China, allegedly hacked AT&T, Verizon and Lumen Technologies to spy on customers."
