At the moment you can only sign in to the community using your password and email address. Your old password will still work and you can still reset passwords in exactly the same way as before.
We have improved the sign in process for managing your account in my.bulb.co.uk by not needing a password. Just put in your email and then click the link we send you. Much easier, as well as being more secure. You can read more about it here. We’re working on bringing this to the community.
