What is Two-Factor Authentication?
Two-Factor Authentication (2FA) is a feature that will keep your account even safer in the event someone manages to get access to your master password. With 2FA, a hacker will not be able to access your data unless they also have a hold of the device you set up Two-Factor Authentication with. Of course, this means that you must always have access to that device (or the back-up solutions that we offer when activating Two-Factor Authentication!)
Two-Factor Authentication needs to be activated on your desktop, using at least Dashlane 2.0 on either Windows or Mac OS X. Two-Factor Authentication cannot be activated from an iOS device (iPhone, iPad, iPod) or from an Android device.
You need to have any TOTP-based mobile authenticator installed on your mobile device to enable the Two-Factor Authentication feature in Dashlane. You can install any authenticator, however, a few examples are Authy (for iOS and for Android), Google Authenticator (for iOS and for Android), and FreeOTP (for iOS and Android). If you do not have a mobile device, you can, for instance, use WinAuth.
How to enable Two-Factor Authentication
- To enable Two-Factor Authentication, go to Tools → Preferences on Windows or select Dashlane → Preferences on Mac OS X.
- Open the Security tab, and click on the Two-Factor Authentication sub-tab. Here, click on the lock icon at the bottom of the window to unlock the Settings (you will be prompted to enter your master password), then click on the switch to enable Two-Factor Authentication.
- Choose one of the two different security levels available for Two-Factor Authentication:
Only when I add a new device to my accountmeans that you will need to authenticate yourself via your second factor only when an unauthorized device is used to access your Dashlane account. Once authenticated, we will never ask you to repeat this step on that device.
Each time I log into Dashlaneis the most secure setting. You will need to authenticate yourself via your second factor each time your Dashlane account is accessed.
Note: you will need to disable Two-Factor Authentication and re-enable it altogether if you wish to switch between security levels.
- Now it is time to use your Two-Factor Authentication app! We are going to use Google Authenticator here, but all Two-Factor Authentication apps normally work like this. Open the Two-Factor Authentication app on your mobile device, tap on the Menu icon located at the top-right corner and choose Set up account to add a new entry. If it’s your first time using a Two-Factor Authentication app, you should be able to add a new entry by choosing Begin setup at the bottom.
- Tap on Scan a Barcode if your mobile device has a camera. If your mobile doesn’t have one, choose Enter provided key instead.
- Then, flash the QR bar code that is currently displayed by Dashlane with your mobile’s camera, or manually enter your Dashlane email address and the secret key displayed above the QR code into your Two-Factor Authentication app. In any case, your Two-Factor Authentication app should then start generating 6-digit codes that change every 30 seconds.
- Enter the code generated by your app into the field provided by Dashlane.
- Dashlane will then offer you two different back-up solutions in case you lose your mobile device or cannot use it anymore:
Choose a back-up phone number. If you lose your mobile device, we will send a code to that number that will allow you to disable Two-Factor Authentication. The back-up number cannot be changed later unless Two-Factor Authentication is disabled in your Dashlane account. If you have changed your cell number, you need to disable Two-Factor Authentication first and then re-enable it with your new phone number.
The other way of disabling Two-Factor Authentication is to use one of the unique back-up codes you will be provided with. Use one of them (in addition to your master password) instead of your second factor to temporarily bypass the Two-Factor Authentication and access your account. Note that each of back-up code can only be used once!
- Make sure to save these codes as a TXT document for later use.
Two-Factor Authentication should then be set-up with your account!
