Google Authenticator is an Android application that improves the security of your accounts. The utility provides randomly generated numbers users should enter besides their login name and password.
Google Authenticator can be helpful if you want more safety for your accounts. The app is especially useful in case you have the same password for several services or often go online from public places.
Just like another similar app Okta Verify, this utility enables the second layer of protection called two step verification. In order to log in to an account, for instance, email, users have to enter an additional numerical code after entering a regular login name and password. These numbers are randomly generated by Google Authenticator and change every minute. Therefore, it is not enough for hackers to just steal your password to get your account because your smartphone or tablet is needed too.
In conclusion, this method of security significantly improves your online safety. On the other hand, you are going to depend more on your mobile device. If you lose your smartphone or need to do a factory reset, it can be very hard to restore your accounts.
