If you forget your password, click on 'Forgot Password' and answer details like your Birth date, Country, City of birth etc. If you answer these correctly you will be asked to answer the 'Hint Question'. The Rediffmail system will then generate a new password and display it on the screen.
You must then login with this new password. After logging in, you can change the password with a password of your choice by going to 'My Settings' > ‘Change Password’. Note: Please note down your new password before you close the window.
