How to fix Dashlane not syncing
When Dashlane stops syncing, new passwords, edits, and deleted items may not appear across your devices.
This guide explains the most common causes and the exact steps to restore sync without losing data.
Dashlane relies on an encrypted cloud sync system tied to your account, device permissions, browser extensions, and network connectivity.
A small issue in any of these layers can make it look like your vault is frozen.
Why Dashlane sync problems happen
Dashlane sync issues usually come from one of a few categories: account authentication, app version mismatch, extension conflicts, offline mode, or device-specific network restrictions.
Understanding the cause helps you choose the fastest fix.
- Outdated app or browser extension: Older versions may fail to communicate with Dashlane servers properly.
- Unstable internet connection: Intermittent connectivity can block uploads and downloads.
- Account session issues: A stale login token can prevent fresh sync activity.
- Conflicting browser data: Corrupted cache, cookies, or extension settings may interfere.
- Device time mismatch: Incorrect system time can break secure authentication flows.
- Temporary service disruption: Dashlane infrastructure or related services may experience short outages.
Check whether Dashlane is actually connected
Before changing settings, confirm that Dashlane is signed in and actively connected.
In many cases, the app is open but not fully authenticated.
- Open Dashlane on the affected device.
- Confirm you are signed in to the correct account.
- Look for any warning about offline mode, session expiration, or sign-in required.
- Check whether the vault shows recent changes from another device.
If you use Dashlane on multiple devices, make one small change on a second device and see whether it appears on the problem device after a few minutes.
That helps determine whether sync is broken in one direction or completely stalled.
Restart Dashlane and the device
A full restart clears temporary memory issues that can block sync.
This is one of the simplest fixes and often works when the app has been running for a long time.
- Quit Dashlane completely, not just minimize it.
- Close the browser if you use the Dashlane extension.
- Restart your computer or mobile device.
- Reopen Dashlane and allow it to reconnect.
If you are using Dashlane in a browser, also restart the browser after closing all windows.
Some extension processes stay active even after a tab is closed.
Update Dashlane on every device
Version mismatch is a frequent reason sync fails.
Dashlane apps, browser extensions, and mobile apps should all be updated to the latest available release.
- Update the desktop app from the official Dashlane source or app store.
- Update the browser extension in Chrome, Firefox, Edge, or Safari.
- Update the mobile app through the Apple App Store or Google Play Store.
After updating, sign out and sign back in if prompted.
Reauthentication often refreshes the secure sync connection.
Verify your internet connection and network restrictions
Dashlane needs a stable connection to sync encrypted data with its servers.
Public Wi-Fi, corporate firewalls, VPNs, and restrictive DNS settings can interrupt that process.
What to test
- Switch from Wi-Fi to mobile data or another network.
- Disable VPN temporarily and test sync again.
- Turn off proxy settings if your device uses them.
- Check whether other apps can reach the internet normally.
If Dashlane sync works on one network but not another, the problem is likely environmental rather than account-related.
In that case, ask your IT administrator whether security policies are blocking Dashlane endpoints.
Sign out and back in to refresh the session
Authentication tokens can expire or become inconsistent after long usage, password changes, or device restores.
Signing out and back in forces Dashlane to establish a new secure session.
- Make sure you know your master password and have access to your two-factor authentication method if enabled.
- Sign out of Dashlane on the affected device.
- Close the app or browser completely.
- Sign back in and wait for the initial sync to complete.
Be patient during the first sync after login, especially if your vault is large.
Large password databases, secure notes, and file attachments can take longer to reconcile.
Check browser extension conflicts
If the issue happens in a browser, the Dashlane extension may be blocked by another add-on.
Ad blockers, privacy tools, script blockers, and password managers can interfere with extension behavior.
- Disable other extensions temporarily.
- Test Dashlane in a private or incognito window if supported.
- Remove and reinstall the Dashlane extension.
- Confirm the browser itself is updated.
In Chromium-based browsers, extension permissions can also affect site access and form detection.
Review whether Dashlane has the permissions it needs to operate on the websites you use.
Clear corrupted cache or app data
Damaged local data can prevent Dashlane from reading or writing sync state correctly.
Clearing cache is especially useful when the app opens normally but changes never appear on other devices.
For desktop browsers
- Clear the browser cache and cookies for Dashlane-related sessions only if needed.
- Reinstall the browser extension after clearing data.
For desktop apps
- Use the app’s repair or reset option if available.
- If necessary, uninstall and reinstall the app from the official source.
For mobile devices
- Force close the app.
- Check whether app updates are pending.
- Reinstall the app if the problem persists after a restart.
Always confirm your data is available on another device before removing local app data.
Dashlane sync is designed to preserve vault content, but it is still wise to verify access first.
Check the system date and time
Incorrect time settings can break authentication certificates and secure connections.
This is a subtle issue, but it can stop sync without producing a clear error.
- Set date and time to automatic on Windows, macOS, iPhone, or Android.
- Confirm the correct time zone is selected.
- Restart Dashlane after changing the settings.
This fix matters most after travel, device resets, or manual time adjustments.
Look for account or plan-related limitations
Although most sync issues are technical, account status can also matter.
If your subscription expired, your sign-in changed, or your organization manages your account, some features may behave differently.
- Confirm you are using the intended Dashlane account.
- Check whether you recently changed your email address or master password.
- For business accounts, ask an administrator whether device policies have changed.
If you are on a shared device or between personal and work profiles, verify that you are not switching between two separate vaults by mistake.
Reinstall Dashlane when nothing else works
If syncing still fails after updates, restarts, and reauthentication, a clean reinstall can remove damaged files or extension state.
This is usually the best next step when one device is the only one affected.
- Confirm that your vault syncs correctly on at least one other device.
- Sign out of the affected device.
- Uninstall Dashlane or remove the browser extension.
- Reinstall the latest version.
- Sign in again and allow the vault to sync fully.
After reinstalling, wait for changes to propagate before making additional edits.
Making repeated changes during initial sync can create confusion about which device has the latest data.
When to contact Dashlane support
Contact support if sync fails across all devices, if the app shows repeated authentication errors, or if you suspect an account-level problem.
Include useful details so the investigation is faster.
- Device type and operating system
- Dashlane app or extension version
- Browser name and version, if applicable
- Exact error messages or screenshots
- Whether the issue affects one device or all devices
Support can help identify server-side issues, account-specific blocks, or bugs that require escalation.
If the problem started after a specific update, mention that timeline clearly.
Quick checklist for fixing Dashlane sync issues
- Confirm you are signed into the correct account.
- Restart Dashlane, the browser, and the device.
- Update the app and extension everywhere.
- Test another network and disable VPN or proxy services.
- Sign out and sign back in.
- Disable conflicting browser extensions.
- Clear corrupted app or browser data if needed.
- Set system date and time to automatic.
- Reinstall the app or extension if the issue persists.
These steps solve the most common cases of Dashlane not syncing and help isolate deeper account or device problems when the issue is more persistent.
