Hi there! I understand you're entering your username and password correctly in the Alight app, but when prompted to select your mobile number for two-factor authentication (2FA), you're not receiving the code. Let's work through this together.

First, a couple of quick questions:
- Have you received 2FA codes previously on this mobile number with the Alight app, or is this your first time setting up 2FA?
- Have you checked if your phone has any message filtering such as spam or blocked numbers?
- Are you connected to a stable mobile network or Wi-Fi when requesting the code?

Meanwhile, here are some troubleshooting steps you can try:

1. Verify Mobile Number Selection: Double-check that you are selecting the correct mobile number on the app for 2FA. Sometimes if multiple numbers are linked, the code may be sent to a different one.

2. Check Message Filtering: Look in your phone's SMS spam or blocked messages folder to ensure the code message is not being filtered out.

3. Resend the Code: On the app, try requesting the 2FA code again and wait a few minutes. Codes can sometimes experience delays due to network conditions.

4. Network Connectivity: Make sure your phone has a good signal or is connected to Wi-Fi. Poor network connections can prevent code delivery.

5. Restart Your Device: Sometimes restarting your phone can resolve temporary SMS delivery issues.

6. Alternate 2FA Methods: If the app supports it, check if you have options to receive the code via email or through an authenticator app (like Google Authenticator).

If after trying these, you still don't receive the 2FA code, it could be an issue with the service provider or your account settings. In that case, contacting Alight support at [email protected] would be the next best step to verify if there is a known issue or to reconfigure your 2FA setup1 10.

Let me know what you find, and we can proceed from there! Are you okay to try these steps now?
