Setting up two-factor authentication is a straightforward process that will reduce the risk of unauthorized access. ## What is two-factor authentication? Two-factor authentication is a security process in which users provide two different authentication factors to verify their identity. Typically, this involves something the user knows (like a password) and something the user has (like a security token). ## Why is it important to have two-factor authentication enabled? The primary goal of two-factor authentication is to fortify security by introducing an additional layer of protection against potential attackers. Even if someone obtains a user's data for logging in, they would still need the second form of authentication to gain access. This additional layer of defense makes it significantly more challenging to compromise accounts. ## For which application was two-factor-authentication enabled? * Configuration Center - used for managing integration on your end (available in [sandbox](https://sandbox.account.ingenico.com/), [pre-production](https://account.preprod.connect.worldline-solutions.com/), and [production](https://account.connect.worldline-solutions.com/)environments) ## What authentication apps should be used? To initiate the two-factor authentication setup process, start by downloading an authenticator app on your mobile device. Two examples of the popular apps are: * Google Authenticator ([Google Play Store](https://play.google.com/store/apps/details?id=com.google.android.apps.authenticator2&hl=en&gl=US&pli=1) or [Apple App Store](https://apps.apple.com/us/app/google-authenticator/id388497605)) * Microsoft Authenticator ([Google Play Store](https://play.google.com/store/search?q=microsoft+authenticator&c=apps&hl=en&gl=US) or [Apple App Store](https://apps.apple.com/us/app/microsoft-authenticator/id983156458)) ## What should be done from your side? 1. Download one of the authenticator apps to your mobile device. 2. Set up the two-factor authentication in the Configuration Center using [our instructions.](https://docs.connect.worldline-solutions.com/documentation/two-factor-authentication.md) 3. Log in to the Configuration Center, providing the one-time password (OTP) from the authenticator app. ## Additional information * In the future, you'll need to provide the one-time password next to your username and password to log in * For each environment ([sandbox](https://sandbox.account.ingenico.com), [pre-production](https://account.preprod.connect.worldline-solutions.com), and [production](https://account.connect.worldline-solutions.com)), you'll need to set up two-factor authentication separately * The one-time password is specific to the device and can't be used with another one * You can always reset the two-factor authentication by following [our guidelines](https://docs.connect.worldline-solutions.com/documentation/two-factor-authentication.md) ## Using the key instead of the QR code to set up two-factor authentication If you can't scan the QR code with your mobile device's camera, setting up two-factor authentication using the authenticator app is still possible. 1. Log in to the Configuration Center ([sandbox](https://sandbox.account.ingenico.com/), [pre-production](https://account.preprod.connect.worldline-solutions.com/), and [production](https://account.connect.worldline-solutions.com/)environment) 2. You'll see the page to set up the two-factor authentication. Click on the "unable to scan code?" link. 3. You'll be shown a key that you must add to the authenticator app (copy and paste the key into the app). 4. Provide the name for your one-time password (we suggest using "Worldline Connect.") 5. In your authenticator app, you'll see the "Worldline Connect" and the one-time password (OTP): a six-digit code that constantly refreshes. Enter this one-time password and press submit. ## Is it possible to reset the two-factor authentication? Yes, you can always reset the two-factor authentication, and there are several ways to do so: * [resetting two-factor authentication yourself](https://docs.connect.worldline-solutions.com/documentation/two-factor-authentication.md#resetting-yourself) * [resetting two-factor authentication by the account admin](https://docs.connect.worldline-solutions.com/documentation/two-factor-authentication.md#resetting-by-admin) * [resetting two-factor authentication by our team](https://docs.connect.worldline-solutions.com/documentation/two-factor-authentication.md#resetting-by-our-team) ## Support For the frequently asked questions regarding the two-factor authentication, please check the [FAQ section](https://docs.connect.worldline-solutions.com/documentation/two-factor-authentication.md#faq) of our guide.
