It doesn’t matter what type of gadget you use. It may be a PC, smartphone, or tablet but it’s important to keep the device secure. With the use of numerous apps, it is imperative that you should see that usage happens in a secure way. For that, the best option is to use two-factor authentication. 2FA works great with Google Authenticator. This app generates OTP based on timestamps. Along with login details the user has to put the 6-digit code. The OTP will only be available to the person who has the secret key for the particular app the user needs to sign-in.
Sometimes it may happen that Authenticator may not work with iPhones. As a result, the apps on which 2FA is enabled will not allow the user to login. In this guide, I will tell you how to fix the issue if Google Authenticator is not working on your iPhone.
