Troubleshooting guide · Features and menus may differ by plan, browser and device

What to check first

Check the browser and operating system compatibility and confirm you have the required authentication method.

Before changing account settings, make sure you are using the correct Dashlane account and a trusted device. Note whether the issue occurs on one website, one browser, or all devices. That distinction helps identify the likely cause.

Step-by-step solution

1. Record the exact symptom and when it began. Avoid entering account credentials into unfamiliar websites or forms.
2. Check the browser and operating system compatibility and confirm you have the required authentication method.
3. Install the legitimate extension or supported app, enter the correct account email, and complete new-device verification.
4. After each safe change, repeat the original action once to see whether the issue is resolved.
5. Check that the vault syncs without creating a second account.

Why the problem may continue

Browser extensions, mobile apps, account sign-in methods, subscription plans, and security settings do not always offer identical features. An outdated browser, an account mismatch, a disabled permission, or a missing recovery option can cause similar-looking problems. Check which situation applies before reinstalling or resetting anything.

How to confirm the fix

Check that the vault syncs without creating a second account. When testing a login or autofill issue, use a trusted website and confirm the correct account is selected. When testing a billing or account change, verify the displayed status and save any confirmation.

What to avoid

• Do not download unofficial installers or browser extensions.
• Do not repeatedly guess credentials or authentication codes.
• Do not remove the only trusted device before checking recovery options.
• Do not export passwords into unprotected files unless a necessary migration requires it.

Frequently asked questions

Will the same instructions work on every device?

No. Some steps differ between the browser extension, Android, iPhone, personal plans, and organization-managed accounts. Follow the interface that is actually available to you.

Should I reinstall Dashlane immediately?

Usually not. First check sign-in, synchronization, browser settings, and recovery access. Removing an app or extension before confirming account access can make troubleshooting harder.

What details should I provide when requesting help?

Share the device, operating system, browser, relevant feature, and exact error wording. Do not include passwords, security codes, or sensitive vault contents.
