Hello, riantopanddhu ,
First of all, try to use the “Forgot password?” option on login page.
After password restoration, you can login and delete all units and geofences from your account.
Then you can create a new account or use your current.
If this does not help, write to us mail firstname.lastname@example.org, in the letter indicate what you wrote to us in the topic on the forum, then we will be able to send additional instructions.
