B1/B2 visa for parent

[km5]

I need to schedule an appointment for my father for a visitor's visa, I used my email address to create an account for scheduling his appointment. Is there any way I can remove his information from my account? Will I be able to use my account to schedule an appointment for myself in the future or will this create any issues and I might have to create a new account for myself?

Any leads are appreciated.

Thanks!!
