This guide walks you through the most common causes of Dashlane error codes and how to fix them effectively. Whether you're using Dashlane on Windows, macOS, Android, or a browser extension, these steps will help get you back up and running.

What Is a Dashlane Error Code?

A Dashlane error code is an alert that appears when the app or browser extension runs into an issue — usually related to:

  • Connectivity (issues with your internet or Dashlane servers)

  • Login problems (invalid credentials or account mismatch)

  • Browser extension errors

  • Outdated software or installation problems

Sometimes, the error code appears as a specific number or message, like "Error connecting to server," "Error code -1015," or simply "Something went wrong."

The good news? Most of these problems are fixable with a few simple steps.

Step-by-Step: How to Fix Dashlane Error Codes 1. Check Your Internet Connection

Since Dashlane requires a stable connection to sync and access encrypted data, the first thing to check is your internet.

  • Restart your Wi-Fi or switch to a different network.

  • If you're using a firewall or VPN, try disabling it temporarily to see if Dashlane works without it.

  • On a work or public network, firewall rules may block Dashlane’s access. In that case, try connecting from a different location.

2. Update the Dashlane App or Extension

Running an outdated version of Dashlane is one of the most common causes of errors.

  • Make sure your app is updated through the App Store, Play Store, or software settings on your desktop.

  • For browser users, update the Dashlane extension and your browser (Chrome, Firefox, Edge, etc.).

Once updated, restart your device or browser and check if the error persists.

3. Clear Your Browser Cache and Cookies

If you’re using Dashlane in a browser and seeing error messages, your browser cache may be interfering.

  • Open your browser’s settings.

  • Navigate to privacy or history settings.

  • Clear cache, cookies, and browsing data.

  • Restart the browser and log in again to Dashlane.

This often fixes login and sync issues.

4. Reinstall Dashlane

If updates and connection checks don’t work, reinstalling Dashlane is a strong fix.

  • Uninstall the Dashlane app or extension.

  • Restart your device or browser.

  • Reinstall the latest version from the official source.

After reinstalling, log in with your account credentials and verify if the problem is resolved.

5. Disable Conflicting Extensions or Software

Other browser extensions (like ad blockers or VPNs) may interfere with Dashlane.

  • Try disabling other extensions one by one.

  • Restart the browser and test Dashlane again.

If you're using another password manager (like LastPass, Bitwarden, or 1Password), it might conflict with Dashlane. Disable or remove it temporarily and try again.

6. Use the Web App Instead of the Desktop App

If the desktop app continues to show errors, log in using Dashlane’s web app from a supported browser. This can act as a temporary workaround while you troubleshoot the installed software.

Make sure to bookmark the site and use a trusted connection for better security.

Special Case: Error Code -1015

Some users report encountering error code -1015 when trying to sign in or connect with older or unsupported Dashlane versions.

Fix:

  • This usually happens when using discontinued Dashlane apps (like old desktop versions or non-supported browser platforms).

  • Install the latest browser extension via Chrome, Firefox, or Edge.

  • Do not use third-party software bundles to install Dashlane—stick to official sources only.

What If You Can’t Log In to Your Dashlane Account?

Sometimes the error may relate to login problems rather than software malfunction.

Try the following:

  • Double-check your email and master password.

  • Use the "show password" option to avoid typos.

  • Use the "Forgot Password" feature if necessary.

  • If you’ve changed devices, Dashlane may require identity verification. Check your inbox for verification emails.
