You can use the link shown to clear out your sign-in information from our system to avoid being redirected to the Register for MyDMV Online Services page.  Then you can use the Forgot your Username tool on the NY.gov ID sign-in page to get a list of all of your NY.gov ID usernames.  If you have more than one e-mail address, though, be sure to check all of them.
I'm still trying to sign up and I got the email from you so what do I do next?
You should enter your username and temporary password on the MyDMV homepage
What if I think I made a typing error entering my photo document?
