As technology advances, account security becomes an increasing concern for people. We are constantly hearing news of security breaches, and phishing scams. To protect yourself from such threats, two-factor authentication (2FA) is a must. In 2FA, you need to provide two types of credentials to log in to your account. While your password is something you know, the second factor could be something only you have, like your phone or biometrics. Using an authenticator app to generate codes for 2FA is an excellent way to enhance the security of your accounts. Here are some of the best authenticator apps for 2FA and other enhanced account security in 2021.
