![]() Security professionals strongly advise against using this method for receiving 2FA codes because they’re more vulnerable to being intercepted by a threat actor.įor example, if you were to become a victim of a SIM swapping attack, in which a threat actor swaps your SIM card to their phone, they would start receiving all your text messages and phone calls. This is the most popular way to receive 2FA codes since it’s the most convenient for users, but receiving 2FA codes this way is also the least secure. SMS text messagesĪnother way you can get 2FA codes is by text message. The 2FA code given to you is time-based so you’ll need to enter it before time runs out, which is usually 30-60 seconds. Once it’s set up, every time you log in to that account, you’ll need to enter the 2FA code generated by the authenticator app. When using an authenticator app, you’ll first need to set it up with your account by scanning the Quick Response (QR) code that is given to you. Google Authenticator and Microsoft Authenticator are two examples of authenticator apps. Authenticator appsĪuthenticator apps are applications you download onto your phone. There are different ways you can receive 2FA codes and some are more secure than others. In the event that your credentials are involved in a public data breach, having a 2FA code on your account would prevent a threat actor from being able to successfully access it. These breaches usually expose customers’ Personally Identifiable Information (PII) and login credentials. Public data breaches are extremely common and often lead to customer data being leaked and published on the dark web. Protects you in the event of a public data breach ![]() It’s strongly recommended that you use more than two authentication factors for your accounts to add that critical extra layer of security. This is because they don’t have the ability to see your 2FA codes – only you do. In the case that someone were to guess your password or compromise it due to weak password practices, requiring a 2FA code would prevent them from being able to gain access to your account. Extra layer of securityĢFA codes, like any other type of MFA, provide your accounts with an extra layer of security. You should use 2FA codes to add an extra layer of security to your accounts and protect yourself in the event of a data breach. To access your account, you’ll need to enter the code sent to you through text message to verify who you are. You typically receive these text messages when you are attempting to log in to your account and have already entered your credentials correctly. SMS OTP codes are sent to you via text message. When using TOTP codes, it’s important to know that once the set time for them runs out, they expire, so you must always enter the most recent code that appears. Some password managers also offer the option to generate and store TOTP codes so you don’t need a separate application. These codes regenerate every 30-60 seconds, so they’re different each time you use them. TOTP codes are typically generated by authenticator apps that you can download on your phone. The first type is Time-based One-Time Passwords (TOTP) and the second is SMS-based One-Time Passwords (OTP). How 2FA Codes Workīefore understanding how 2FA codes work, you first have to know the two types of 2FA codes. For example, when logging in to an account, instead of solely entering your credentials, you would also have to provide a second method of verification by entering a code from an authenticator app or one that is sent to your phone.Ĭontinue reading to learn more about 2FA codes and how you can use them to protect your accounts.
