To increase the security of your account, Two-Factor Authentication can be enabled from the Preferences of the Dashlane application. An additional code will then be required each time you need to authorize a new device to access your account, or even each time you log in to your account (that is for you to choose). Please note that Two-Factor Authentication completely replaces the security codes which would be normally sent to you by e-mail when authenticating a new device, or resetting/deleting your account.
If you have a U2F Security Key and a Premium subscription, you can add this key to your Dashlane account for an extra layer of security and convenience.
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.
1. To enable Two-Factor Authentication, go to Tools → Preferences on Windows or select Dashlane → Preferences on Mac OS X.
2. 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.
3. Choose one of the two different security levels available for Two-Factor Authentication:
- Only when I add a new device to my account means 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 Dashlane is 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.
4. 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 symbol 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.
5. Tap on Scan a Barcode if your mobile device has a camera. If your mobile doesn’t have one, choose Enter provided key instead.
6. 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.
7. Enter the code generated by your app into the field provided by Dashlane.
8. 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 both your mobile device, we will send a code to that number that will allow you to disable Two-Factor Authentication. You cannot change this back-up number later, therefore if you get a new phone, you will have to disable Two-Factor Authentication and then re-enable it again with your new 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!
9. Make sure to save these codes as a TXT document for later use.
