Can you remove ALL 'multiple passwords' from a multiple password id?

Hi

I have an id that has been secured with ‘multiple passwords’ that I no longer require to be so secure?

Does anyone know if it is possible to remove ALL ‘mulitple passwords’ from it (assuming I know enough of the required passwords to access it) so that it operates from then on like a normal, or the original id

I only ask as the ‘Edit Multiple Passwords’ UI allows me to delete / reduce the required ‘multiple passwords’ to 1, but not to 0 - i.e. forcing the id to only prompt me for the ‘id’ password and not a user/password combination configured via the ‘Multiple Passwords’ UI

Regards

Paul
