I have 3 e-mail addresses. Since the way we log in has changed I have found that I am presented with a choice of 5 addressess. 2 of them are duplicated . Both duplications will work with either one.
Is there any way to take out the duplicate 2 entries so there is just a choice of the 3 e-mail addresses
It is your web browser that stores the username and password. You will need to go into your browser settings and go to either Stored Passwords or something similar and look for your BT accounts and delete the ones you do not want stored.
If per chance you delete the wrong one, when you enter the details for the one you deleted you should be offered the chance to store it again the next time you use it.
