Is it OK to use text messages for 2-factor authentication? [Ask ZDNet]

Welcome to the first installment of a new weekly advice column, Ask ZDNet. It’s a time-honored editorial format, like Dear Abby but with a much better grasp of modern tech. 

This week, we tackle three thorny questions: Are text messages too dangerous to use as a second factor for 2FA? Do you really need Windows 11 Pro edition? And why do smoke detector batteries always seem to die in the middle of the night? 

If you’ve got a question about any of the topics ZDNet covers, one of our team of editors and contributors probably has an answer. If they don’t, we’ll find an outside expert who can steer you in the right direction. 

Questions can cover just about any topic that’s remotely related to work and technology, including PCs and Macs, mobile devices, security and privacy, social media, home office gear, consumer electronics, business etiquette, financial advice … well, you get the idea.

Ask away.
