IMPORTANT: This information applies to Dashlane's desktop apps, which are no longer available. Our desktop app allowed you to use a U2F security key as a second layer of Two-Factor Authentication (2FA). We will not be adding this aspect of U2F security key support to the web app in the near future. However, if you own a U2F security key and want to use it to make logging in to Dashlane easier, learn how you can use a security key instead of your Master Password to log in to Dashlane. You can continue to use the U2F feature on Android if you have already added a U2F security key to your Dashlane account.
About U2F on the Dashlane desktop app
Dashlane supports the FIDO Alliance™ universal two-factor (U2F) authentication standard, and we have partnered with Yubico, the provider of U2F YubiKeys. FIDO U2F is a convenient and secure way to complete two-factor authentication, freeing you from having to hunt for a code whenever you need to authenticate your Dashlane account.
After adding a U2F security key to your Dashlane account using only the desktop app, and with nothing else than a simple touch (depending on the U2F security key model you are using), your key executes a public and private key exchange, successfully authenticating you into your Dashlane account on the desktop app or your Android device.
Note that while your U2F security key replaces entering 2FA codes, it does not replace your two-factor authentication app. If you lose your key, Dashlane will ask you to enter the code from your 2FA app.

What is U2F, and what does it protect you from?
Dashlane was the first password manager to support U2F, an innovative and universal two-factor authentication standard backed by Yubico and the FIDO Alliance. U2F is an open authentication standard that brings convenience and security to your Dashlane account by allowing you to complete two-factor authentication (2FA) using a security key instead of having to enter codes generated by a two-factor authentication application.
Real-time challenge-response schemes like U2F address vulnerabilities with one-time passwords (OTP), such as phishing and various forms of man-in-the-middle attacks. As the legitimate server is issuing the challenge, if a rogue site or middle-man manipulates the flow, the server will detect an abnormality in the response and deny the transaction.
If you do not have a security key that is U2F-compatible, you will not be able to complete these steps. If you possess a security key compatible with both OTP and U2F, we strongly recommend that you do not use its OTP function to replace your two-factor authentication app.
Two-factor authentication via U2F is a Premium feature only. This means you can add a U2F security key to your Dashlane account only if you have a Premium subscription. Premium trials do not unlock our U2F feature.
How to add a U2F security key to your Dashlane account
To add a U2F security key to your Dashlane account, two-factor authentication must already be enabled. If you haven't done so, learn how to enable two-factor authentication.
To add a U2F security key:
- Open the Preferences of your Dashlane app (from the Tools menu on Windows or the Dashlane menu on Mac OS X).
- Go to the Security tab and then the two-factor authentication sub-tab.
- Ensure that two-factor authentication is ON.
- Next to the U2F security key, click Add.
- Name your U2F security key.
- Plug in your U2F security key and tap the key or gold disk, depending on your key. If your security key was already plugged in and does not have a button or gold disk, you'll have to unplug it and then plug it back in again.
Dashlane will display the following message to tell you it's added your U2F security key. Click OK.
If you want to review the keys added to your Dashlane account or add another key, click Edit next to U2F security key.
How to sign in to your Dashlane account with your U2F security key
Now that you've set up two-factor authentication via U2F, you can start using it.
It is important to note that your U2F security key assumes whatever security level you chose when setting up two-factor authentication. Depending on your choices during setup, you need to authenticate with your security key either only when adding a new device or each time you log in to Dashlane. If you want to change this setting, please disable two-factor authentication and enable it again while choosing your preferred setting. Learn more about protecting your account.
On Windows or Mac OS X
- To log in to Dashlane, open Dashlane, enter your Dashlane email address and Master Password and click on Log in.
- Insert the U2F security key added to your Dashlane account and select the key or gold disk, depending on your key. If your security key was already plugged in and does not have a button or gold disk, you'll have to unplug it and then plug it back in again.
On Android or iOS
On the web app
Unfortunately, you will not be able to sign in to our web app using two-factor authentication via your U2F security key. But we do support Yubikeys as an alternative to typing your Master Password (similar to using Face ID on an iOS device).
You'll still have to use security codes generated by the two-factor authentication app on your phone. To do so:
- Open our web app, provide your Dashlane email address, and click on Log in.
- Open your two-factor authentication app on your mobile device.
- Copy the 6-digit code shown in your two-factor authentication app into the Security code field on the web app.
- Enter your Master Password in the first field, choose a name for this computer or device if you like (such as My laptop, Jim's computer), and click Log in.
How to delete a U2F security key from your Dashlane account
You can delete a U2F security key only from Dashlane on Windows or Mac OS X and only if two-factor authentication is enabled for your account.
To remove an existing U2F security key from your Dashlane account:
- Go to the Security tab in Dashlane's Preferences and then to the two-factor authentication sub-tab.
- Click Edit next to U2F security key.
You'll see a list containing all U2F security keys added to your Dashlane account.
- Click Delete next to the key you want to remove.
This will only delete the U2F security key from your account and will not disable two-factor authentication. Learn how to disable two-factor authentication.
How to sign in to your Dashlane account if you lost your U2F security key
If you lost your U2F security key, you can always log in to Dashlane with your two-factor authentication app instead.
To log in using your two-factor authentication app:
- In the Dashlane login window, click Use mobile authenticator instead.
You're asked to enter a code generated by the app you used to enable two-factor authentication, as shown in the following example.
If you do not have access to the device you used to set up two-factor authentication, please review the list of available options.
