Do you use Gmail? If so, it’s probably a good idea to set up two-factor authentication to ensure that even a stolen password isn’t enough for someone to break in. You can use SMS (text message) or, preferably, more secure methods like the Gmail mobile app to confirm each new login attempt.

It’s possible to log in to Facebook with your phone number and to send SMS messages via Facebook Messenger. However, there’s some risk involved, as your number might be sold to marketers or be used by strangers to look up your profile without even knowing your name. Stick with your email address if possible.

If you use two-factor authentication, it’s best to rely on codes sent to other devices or applications such as Duo or Google Authenticator instead of SMS texts. That’s because SIM hacking is on the rise. This practice entails a cyberattacker tricking a customer service representative into reassigning a phone number to a new SIM card.
