However, some methods of 2FA are inherently insecure. In addition to what you know (your username and password), you use something that only you have - a phone, an app or a specialized hardware token, in order to login securely.

Two-factor authentication (2FA) is currently the most common way how you can protect your online accounts from unauthorized access.
