Hi! I’m Grace. I see you’re having trouble logging into the Lepro LampUX app because it’s asking for an account number and password you never had. Let’s figure this out together.

Just to clarify: have you ever created an account within the LampUX app before? Sometimes, new users need to register first before logging in, or the app might be asking for details related to registration that you missed. Also, are you using the latest version of the LampUX app on your Mac running macOS 10.15.7?

Here’s a step-by-step to get you started:

1. Check for Account Registration
If you haven’t registered an account yet, you’ll need to do so inside the LampUX app. Look for a “Sign Up” or “Register” option instead of “Login.” Creating an account will prompt you to set a password. The “account number” might be misinterpreted; often, the app expects your registered email or username.

2. Password Recovery Option
If you believe you previously had an account but forgot credentials, check the app’s login screen for a “Forgot Password” link. Using that will send a reset link to your registered email to create a new password1.

3. Reinstall the App
Since you’re on macOS 10.15.7, make sure your system supports the latest app version. Try uninstalling and reinstalling the LampUX app from a trusted source to ensure no corrupted files causing login issues.

4. Factory Reset Your Device
If your device (such as smart bulbs) is prompting this login strangely, sometimes a factory reset of the bulbs or LampUX devices helps. Usually, switching the lamp on/off several times puts it into reset mode — check the manual for your lamp model for precise instructions5.

Could you please tell me more:
- Are you trying to log into the app for the first time or after some time?
- Do you remember ever registering an account with Lepro LampUX?
- Which exact device or lamp are you connecting to?

That way I can guide you more precisely!
