Do I need a phone for Dashlane 2-factor authentication?

No. Dashlane names Google Authenticator, Microsoft Authenticator and Duo Mobile, but it only checks the six-digit token, and any standard authenticator produces it. The Authenticator extension reads the QR code straight off the Dashlane page and generates the tokens in Chrome. Dashlane does ask for a phone number, but only to text you recovery codes.

Should I choose every login or only new devices?

Only new devices asks for the token when Dashlane meets a device for the first time; every login asks each time and needs an internet connection whenever you open your vault. To change your choice later, turn 2FA off and on again — you will get new recovery codes.

What if I lose access to my authenticator?

On the login screen select “Use a recovery code”, log in, and use a second recovery code to turn 2FA off — then set it up again. Without saved codes, select “Reset 2FA” to get two new ones by text to your setup number. Keep the extension’s automatic backups on too, so a reinstall does not cost you the token.

Why does Dashlane say my token is wrong?

Usually the computer clock is off — Dashlane’s own help warns that the device with the authenticator and the one with Dashlane must show the same time. Turn on automatic date and time and try the next token. If it still fails, remove the account from the extension and set 2FA up again.

Dashlane Authenticator App — Turn On 2-Factor Authentication

Dashlane holds the passwords to everything else, so whoever gets into it gets into all of it. With 2-factor authentication on, your Master Password alone is not enough: Dashlane also asks for a six-digit token from your authenticator — on a new device, or at every login if you choose. Dashlane can store 2FA codes for your other logins, but its own token belongs somewhere else.

Turn on 2-factor authentication in Dashlane

2-factor authentication is turned on in Dashlane in a computer browser, through the Dashlane extension. A passwordless Dashlane account has no 2FA settings, and neither does one you sign in to through your organization’s single sign-on — ask your plan admin. Admins of a professional plan can enforce 2FA for members in the Admin Console’s policy settings.

Log in to Dashlane in your browser on your computer.
In the “Vault” menu in the top left of the page, select “Settings”, then “Security settings”.
Turn on “2-factor authentication” and enter your Master Password if Dashlane asks for it.
Choose whether to use 2FA every time you log in or only on a new device, then enter your mobile number for recovery codes — select “Continue” after each.
Dashlane shows a QR code and a setup code. Leave it on the screen and add it to the extension as described below — then select “Continue”, enter the token and select “Confirm”.

Dashlane’s own instructions

Add Dashlane to Authenticator

Install 2FA Authenticator from the Chrome Web Store and pin it to the toolbar, so its icon is one click away.
Leave the Dashlane page with the QR code open. Click the Authenticator icon, then “Add Account” → “QR Code” → “Scan QR from screen”.
The account appears in the list with a six-digit code that changes every 30 seconds. Rename it if you like — the name is only for you.
Go back to Dashlane and type the current code into the confirmation field. If it is about to expire, wait for the next one.
Dashlane confirms that two-factor authentication is on. From now on it will ask for a code when you sign in — click the extension icon and copy it.

No QR code, or it will not scan? Look for the option to enter a key manually on Dashlane’s setup screen, copy the key, and add it in the extension with “Add Account” → “Manual” → “Secret Key”.

Download your Dashlane recovery codes

Right after you confirm the token, Dashlane shows a list of recovery codes: download them and keep them on a device other than this computer, then select “Done”. Getting back in without the authenticator takes two of them — one to log in and one to turn 2FA off. If you lose them, Dashlane can text two new ones to the number you gave during setup, and on a professional plan that enforces 2FA your admin can generate new ones. Turning 2FA off and on again replaces the old codes.

The code is not accepted?

Almost always the computer’s clock. The codes are calculated from the current time, so a clock that is a minute off produces codes that look right and are refused. Turn on automatic date and time in your system settings — step-by-step for Windows, macOS and Linux.

If the clock is right, check the key itself: paste it into the TOTP code generator and compare the code with the one in the extension. If they differ, the key was copied wrong — add the account again.
