Hi there, @sumanta_tewari.
Is there any error message or prompt message when attempting to log in to your account? Please specify or attach a screenshot, this will help us identify what causes the issue.
Here's a workaround to help you log in to your account:
- On the sign-in page, select I forgot my user ID or Password, then enter your phone number or email address and click Continue.
- Follow the on-screen instructions. If you used your email address to verify your account, you'll receive an email with your user ID.
- Please check your spam or junk folder f you don't receive an email from us within an hour.
- If you don’t have access to the email you used when you created your account, you can request to change it.
Here are some common sign-in issues and how to fix them: Get help if you can't sign in to your account.
Let me know if it works for you by leaving a comment on the thread. Have a great day.
