Hi @jeeva t
Thank you for posting your query on Microsoft Q&A.
We have a guide here on how to reset the users password via the Entra admin portal -
Sign in to the Microsoft Entra admin center as at least a Password Administrator.
Browse to Identity > Users > All users.
Select the user that needs the reset, then select Reset Password.
Do let me know if you have any further questions, I would be happy to help!
