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 into 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.
The feature is currently not supported on iOS. Instead, you may still wish to use two-factor authentication. For instructions on using 2FA on your iPhone, see here.
