Im having some problems about login registered account

I sign up account  nda@ymim.tech and while verify domain "ymim.tech" , unfortunately i closed my browser

And then I go back to verify again, but I can not login with registered account before

I got message need to verify account to login, but i have no any way to login

How can I delete this account and re-sigup again?

Please help me

Thanks so much

An,
