• Two-factor authentication (2FA) malfunctions.
  
  

• Dashlane web app loads slowly or not at all.
  
  

Whether you’re using the mobile app, desktop platform, or browser extension, the troubleshooting steps below can help restore functionality.

Step-by-Step Solutions to Fix Dashlane Not Working

1. Restart the Application or Device

Sometimes, the issue is temporary and can be resolved with a simple restart.

• On desktop: Quit Dashlane completely and relaunch it.
  
  

• On mobile: Force-close the app and reopen it.
  
  

• On browser: Close all tabs, restart the browser, and try again.
  
  

Restarting clears memory and restarts background processes that may be stuck.

2. Check Your Internet Connection

Dashlane requires a stable internet connection for syncing passwords, verifying login credentials, and connecting with its servers.

To troubleshoot connectivity:

• Ensure Wi-Fi or mobile data is active.
  
  

• Restart your router or switch networks.
  
  

• Disable VPNs or proxy settings that may interfere with Dashlane.
  
  

If you're offline, some features (like accessing your vault in offline mode) may still work, but syncing and updates won't.

3. Update Dashlane and Your Browser

Using an outdated version of Dashlane or your browser can cause compatibility issues.

• Mobile app: Check your device’s app store for updates.
  
  

• Browser extension: Visit the extensions or add-ons manager and ensure Dashlane is updated.
  
  

• Web app: Dashlane’s web version updates automatically, but clearing cache helps load the newest version.
  
  

• Browser: Keep Chrome, Firefox, Edge, or Safari up to date to ensure smooth performance.
  
  

Regular updates improve security and fix bugs that may cause malfunctions.

4. Clear Browser Cache and Cookies

If Dashlane isn’t autofilling or the browser extension appears unresponsive, the issue could be a corrupted cache.

To fix this:

• Go to your browser settings.
  
  

• Clear cookies and cached data.
  
  

• Restart your browser and try again.
  
  

This can help Dashlane load properly and restore lost functionality.

5. Check Extension Permissions

Dashlane browser extensions require specific permissions to function correctly.

To verify permissions:

• Click on the Dashlane icon in your browser.
  
  

• Go to settings or “Manage Extensions.”
  
  

• Ensure the extension has permission to run on all sites and read page content.
  
  

• Toggle the extension off and back on.
  
  

If permissions are restricted, Dashlane may not be able to read website fields or offer autofill suggestions.

6. Log Out and Back In

If your passwords aren't syncing or your vault looks empty, a session refresh might help.

Steps:

• Log out of Dashlane completely on all devices.
  
  

• Log back in using your master password.
  
  

• Wait a few moments for syncing to complete.
  
  

This can resolve sync conflicts and refresh your account connection.

7. Disable Conflicting Extensions or Software

Some browser extensions or security software can interfere with Dashlane.

Common culprits include:

• Ad blockers
  
  

• Script blockers
  
  

• Other password managers
  
  

• Antivirus/firewall software
  
  

Try disabling them one at a time to identify the conflict. Once found, you can either whitelist Dashlane or adjust your settings to allow compatibility.

8. Reinstall Dashlane

If none of the above solutions work, a fresh installation may be needed.

On desktop or mobile:

• Uninstall Dashlane completely.
  
  

• Restart your device.
  
  

• Reinstall from the official source (app store or Dashlane’s website).
  
  

• Log in and set up as new.
  
  

On browser:

• Remove the Dashlane extension.
  
  

• Restart your browser.
  
  

• Reinstall the extension and log in.
  
  

Reinstallation can clear corrupted files or settings that may be causing Dashlane to fail.

9. Fix Autofill Issues

If Dashlane isn’t autofilling login fields, try the following:

• Check that Dashlane’s autofill feature is enabled in the app or extension settings.
  
  

• Ensure the login fields are not on unsupported or custom-coded websites.
  
  

• Manually add login details and try autofilling again.
  
  

• Adjust autofill permissions in your browser settings.
  
  

Dashlane uses advanced autofill technology, but on some websites with non-standard code, you may need to fill in manually once and save the credentials again.

10. Resolve Two-Factor Authentication Problems

If 2FA codes aren't working or the prompt isn't showing:

• Check that your mobile device’s date and time are set correctly.
  
  

• Use the most recent authentication code (TOTP changes every 30 seconds).
  
  

• Reinstall your authenticator app if needed.
  
  

• If you’re locked out, use recovery codes if you saved them during 2FA setup.
  
  

Specific Fixes for Mobile Users

If Dashlane isn't working on your smartphone:

• Make sure the app is not restricted in the background by battery-saving settings.
  
  

• Enable biometric login (Face ID or fingerprint) for faster access.
  
  

• Check app permissions for storage, internet, and notifications.
  
  

• Ensure your device OS is up to date.
  
  

Specific Fixes for Web App Users

If the Dashlane web app isn’t loading:

• Try a different browser to rule out browser-specific issues.
  
  

• Disable any content blockers or pop-up blockers temporarily.
  
  

• Refresh the page using Ctrl + F5 (Windows) or Command + Shift + R (Mac).
  
  

• Try opening the web app in Incognito or Private Browsing mode.
  
  

Preventing Future Issues with Dashlane

While it's normal for any software to have occasional hiccups, here are tips to reduce the chances of Dashlane failing again:

• Regularly update Dashlane and your browser.
  
  

• Clear your browser cache monthly.
  
  

• Keep two-factor authentication enabled but properly set up.
  
  

• Avoid using multiple password managers simultaneously.
  
  

• Monitor Dashlane’s status page or social media for known outages.
  
  

• Back up your data periodically using secure export options (only if needed and stored safely).
