How can i delete my orkut account and i don't know my pass word?

To delete your Orkut account without knowing your passWord, you can use the "Forgot PassWord" option on the login page to reset your passWord via your registered email address. Once you regain access to your account, navigate to the account settings and select the option to delete your account. If you no longer have access to your email, you may need to follow google's support procedures for account recovery. However, please note that Orkut was officially shut down in 2014, so accessing your account may not be possible.
