@RajkumarIlanchelian thank you for helping to resolve the issue. It has been fixed now. I'm not sure if you have any influence over the support team, but the email that eventually came through looked like a generic sign-in help email. You have to scroll to the very last line at the bottom to see them mention "Important: By providing this information, you consent to Autodesk sending you a One-Time Password to the email address you are currently using to communicate with us."
For anyone else struggling with this issue, the email you will receive looks like the below. Once I responded to this, I then received a phone call and they provided the OTP over phone while I was signing in and then made sure I changed my email address as well. Make sure you have a spare email address available to use.
I’m from Autodesk's Client Services team, and I will be assisting you with signing into your Autodesk account.
Before proceeding, please confirm that you have checked the following:
Emails from signin@autodesk.com and noreply@autodesk.com are not blocked by you or your organization.
The email is not in your spam or junk folder.
Your email mailbox is not full and has space to receive new messages.
If the issue persists after checking all of the above, please reply with these details:
1. What URL do you see in your browser’s address bar on the sign-in page?
Please reply with one of these options:
A. accounts.autodesk.com
B. signin.autodesk.com
2. If applicable, share a screenshot of the page where you're experiencing the problem.
Once we receive your response, we’ll guide you through the next steps.
