Hi there! I understand you're having trouble logging into the Driver Pulse app using the last four digits of your SSN. Let's work together to resolve this.

Can you please confirm whether you're entering the last four digits correctly? Sometimes it can help to double-check for any typos. If you’re confident that the information is correct, there are a few things we can try:

1. Clear Cache and Cookies: Sometimes, clearing your browser's cache and cookies can resolve login issues. You can do this in WebKit by accessing Settings > Privacy > Clear Browsing Data.

2. Update your App: Ensure that your Driver Pulse app is updated to the latest version. An outdated version may have bugs or issues with logging in.

3. Try a Different Browser: If possible, try logging in using a different browser or device to see if the issue persists.

If you've already tried these steps and are still unable to log in, the issue may be more specific. I recommend checking the following how to login to Driver Pulse for additional guidance.

If you're still having difficulties, please let me know, and we can explore further options, such as contacting support for assistance. Are you satisfied with the solution I provided?
