If Dashlane sync is not working, your passwords and account information may not update across your devices. This can happen because of connection issues, outdated apps, or account settings.

Check Your Internet Connection Make sure your device has a stable internet connection. A poor connection can prevent Dashlane from syncing your information correctly.
Verify Your Account Confirm that you are signed in with the same Dashlane account on all devices. Different accounts will not sync the same data.
Update Dashlane Install the latest version of the Dashlane app or browser extension. Updates can resolve common syncing problems.
Restart the App Close Dashlane completely and open it again to refresh the connection and restart the sync process.
Check Sync Settings Review your account settings and make sure syncing is enabled on your connected devices.
