AuthToken Generation Error

AuthToken Generation Error

https://accounts.zoho.com/apiauthtoken/nb/create?SCOPE=ZohoCRM/crmapi&EMAIL_ID=[Username/EmailID]&PASSWORD=[Password]&DISPLAY_NAME=[ApplicationName]

I had tried this url to generate AuthToken but inspite for entering correct username and password it shows "Invalid Password".

Please help me as soon as possible.
Thanks.
