Today is my last working day at Accenture. What will happen to my blind account?

At midnight UTC, Accenture runs a job to de-register all the accounts that you created using company id including Blind. So good luck OP for the next adventure!!

It will work. Only if you want to reset password or forgot password, you won't be able to recover it since email will go to your work email account. Otherwise Blind won't know if you are still employed or not.

Blind will ask you to Reverify your account sometime and you won’t be able too causing it logout

Gonna self destruct in a plume of smoke
