Two-Factor Authentication is also known as 2FA, means an additional login code that is needed to login into your account. These days, accounts getting hacked have become normal, so you need to be very careful by keeping your passwords strong and using two-factor authentication.

If the hacker tries to steal your password and username, it will still be hard to get your account, as it will ask for an authentication code that comes on your smartphone if you use Two-Factor Authenticator apps. When you use 2FA, any service you log in to will ask you two authentications; one is the password you know, and the other is the authentication code in the app.

Using Two-factor authenticator apps on smartphones has fewer options as compared to websites. Here are some of the Two-Factor Authenticator Apps for Android devices.
