Hackers have had a lot of success tricking wireless carriers into switching the SIM card associated with a person's phone number and receiving the two-factor codes sent to your phone number. Most websites give you the option to receive your 2FA codes through SMS texting or by using a dedicated app such as Google Authenticator, but we don't recommend using SMS. As privacy concerns continue to rise amid breach after breach, two-factor authentication (along with a password manager) is an important step that can help fortify your online security by making it harder for others to take over your accounts. Two-factor authentication adds an extra layer of security to your online accounts by requiring a randomly generated six-digit code after you've entered your password. Thankfully, both iPhone and Android let you easily transfer your accounts from one phone to another. Without those codes, you could very well end up locked out of your online accounts. Using a two-factor authentication app like Google Authenticator is the preferred way to protect your accounts (better than text), and if you're a user, it's important that you move your information over when you get a new smartphone, like the iPhone 13 or Pixel 6, for example (it's the holidays, so many people will be getting upgrades!).ĭoing so will ensure you can still access your two-factor codes and sign in to those accounts on your new phone. Don't forget to transfer Google's Authenticator app when you set up a new phone.
