Facebook and Twitter admit that marketers accessed the phone numbers people gave them for security verification. Here’s how to protect yourself without handing over your digits.
While most major sites allow authenticator apps, some are still stuck on phone numbers. But you have an option here too: Instead of your cellphone number, give them a Google Voice number.
For years, Google has allowed people to get free virtual phone numbers that can receive calls and texts just like a real number. (You can access it online or have messages forwarded to another phone.) Using them when you sign up for services is a great way to cut down on spam phone calls and also ensure that the company doesn’t have your real phone number forever. (A dedicated Gmail for spam is another good idea.)
