Hi there! I understand you're having trouble locating or accessing your sign-in account for the NYC ACCESS HRA app. Let me help you get this sorted out.

First, just to clarify:
- Are you trying to sign in on the web or via the mobile app on your Mac?
- Do you remember if you have an ACCESS HRA username or if you typically use your email address to sign in?
- Have you tried the password reset option yet, or is the system not recognizing your account at all?

Meanwhile, here’s a straightforward way to check:

1. Visit the official ACCESS HRA login page here: https://a069-access.nyc.gov/accesshra/login
2. Enter your email address or ACCESS HRA username if you have it.
3. If your account is not recognized or you forgot your password, use the "Forgot Password?" link to reset it. This will send password reset instructions to your email.
4. If you still cannot locate your account or reset password successfully, you can request help online without needing to log in:
Go to the ACCESS HRA Help form and select the reason “I need help with my ACCESS HRA account/login/password” (source).

Because you’re using a Mac with OS X 10.15.7, be sure to try logging in using a reliable browser like Safari or Chrome and clear your browser cache if you’ve tried multiple attempts without success.

Could you let me know what step you’re on or if you see any error messages? That way, I can guide you with more specific steps.
