In order to prevent others from knowing my login username to my protonmail account, , it woul be very helpful if one could disable or enable the use of additional email addresses as user login name. Currently I can login into protonmail with all my email addresses. But I would like to choose which adress I exclusivley use for login into my account. For this it would be very helpful, if I could enable or disable for every email adress the login option. This would enhance account security drastically because "regulary" used email addresses to not reveal the username of the account.
