This page contains instructions for using U2F on a mobile device. For general information about using U2F devices and Dashlane, please see U2F functionalities with Dashlane.
The instructions below assume you have already added a U2F security key to your Dashlane account. This is currently only possible from our desktop app. For instructions on how to do so, see How to add a U2F security key to your Dashlane account.
Remember that two-factor authentication via U2F is a Premium feature only. Premium Trial accounts and pre-2.0 users do not have the U2F feature.
Starting with version 6.1923.0 of Dashlane, you can use the U2F feature on Android, either with the NFC feature by touching your Yubikey to your phone, or else by plugging your USB key directly in to your phone.
To be able to use the NFC U2F feature with Dashlane, you will first need to make sure that you have a mobile device with NFC capability enabled and an NFC Yubikey.
The easiest way to check if your device has NFC capability is to look for the small NFC tile in your quick settings menu.
Otherwise, go to Settings and verify if NFC is among the other connectivity options like WiFi or Bluetooth.
Once you have verified that your device has NFC capability, and you have added a U2F key to your account, open Dashlane on your Android device.
After you have entered your Dashlane ID, the screen shows that U2F authentication is available with the logo of a little Yubikey on the right of your screen.
Remember that if you do not have your Yubikey with you or do not have the possibility to use it, you can always enter the code from your two-factor authenticator app on the line to the left of the Yubikey logo.
At this point, simply touch your Yubikey to the back of your device so it can recognize your key, and you will see the second authentication screen where you will be prompted to enter either your Master Password, your PIN or your fingerprint, depending on the settings you chose for your account.
Using the USB connector
If you do not have NFC capability on your Android device, you can still use your Yubikey by plugging it into your phone with the USB plug, either directly or with an adaptor.
Once you open Dashlane, and after your email address has been entered, the screen shows that U2F authentication is available with the logo of a little Yubikey on the right of your screen.
At this point, plug in your Yubikey. Be sure to plug it in with the correct orientation, or else the key will not be recognized and nothing will happen!
Once your device recognizes the Yubikey, it will prompt you to allow it to be used for authentication.
After you allowed your device to use the key, you will get this pop-up message saying your key was recognized. At this point, tap on the button or gold disk on your Yubikey. You should feel a slight vibration of your phone when the key is recognized.
You will then be shown a second authentication screen where you will be prompted for either your Master Password, your PIN or your fingerprint, depending on the settings you chose for your account.
Starting with version 6.1931.0 of Dashlane, you can use the U2F feature on iOS by plugging your Lightning Yubikey directly in to your iPhone or iPad.
Please note that on iOS we currently only support Yubikeys with a lightning port and that are plugged directly in to your iOS device. If you plug a USB Yubikey in to your iOS device with an adaptor, it will not be recognized.
Once you open Dashlane, and after your email address has been entered, the screen shows the Two-Factor Authentification screen, where you are prompted to enter your verification code. Here, you will have the possibility to tap on Use security key in the bar at the top of your keyboard.
Remember that if you do not have your Yubikey with you or do not have the possibility to use it, you can always enter the code from your two-factor authenticator app on this screen.
Note: You will be shown the Use Security key message as soon as you have the U2F feature activated for your account and a Yubikey registered, even if the key is not a lightning Yubikey, as there is no way for us to know which type of key you registered for your Dashlane account.
At this point, you will be prompted to plug your Yubikey in and authenticate by touching the gold buttons on each side of your key.
When the Yubikey is recognized, you will see the message just above the keyboard change and switch to "Authenticating".
Finally, you will be shown a second authentication screen where you will be prompted for either your Master Password, your Touch ID or Face ID, depending on the settings you have chosen for your account.
