I have a shared e.mail account and when I log into my e.mail, 2Fa sends a pin no. to my mobile phone which is very inconvenient for the other person. I asked BT for help to avoid this and my e.mail went to the Executive Complaints team. They more or less said that I had to accept the situation , although in one e.mail they did say that I might be able to have the pin no. sent to a shared landline. When I pressed further my " complaint" was closed by BT who suggested I take matters to the ombudsman. Has anyone else had this sort of experience? If so, has the matter gone to the ombudsman and with what result.
There are numerous posts about 2FA and BT will not remove it. reading the other posts may give you a suggestion of how to solve your problem
2FA can only be sent to one mobile number and I doubt there is a procedure where it can be sent to two mobile phone numbers or for instance for an email account that is shared by more than two people.
The email account is "owned" and managed by the BT Broadband account holder and as such any PIN number is sent to the BT Broadband account holder's chosen mobile number or any email account they have chosen to receive it.
If the BT Broadband account holder wishes others to access their email account that is entirely their decision and it is not BT's responsibility to accommodate another users use of that email account.
If the BT Broadband account holder wants to they have another 10 email accounts allocated to them that they can "gift" to family and friends or anybody else they choose and if the account holder follows the correct procedure those email account will be "gifted" and this in turns transfers the "ownership" and management of the email account to the recipient and this email account can in turn have 2FA set up on that and the recipient will then have the 2FA sent to their chosen number.

If you are both using a shared email account you should consider using an email client or email app on your devices in order to access the email account.
This will negate the need for 2FA to be used as the email client/app is device specific and the email account can not be accessed unless the security of that device is overcome where as using a web browser (webmail) can access the email account using any device any where in the world that has a web browser hence the need for enhanced security.
If you complain to the Ombudsman you will need to go through BT's complaint procedure allowing them six weeks to resolve the complaint or get a deadlock letter explaining why it has not been resolved.
I find the concept of sharing a personal email address bizarre in the extreme. Why on earth would anyone want to?
As has been said, the easiest way to avoid having to contend with 2FA every time you want to look at your email, is to use an email client. You'll need your password and have to contend with 2FA just once, when you set up the account. After that, opening the email client app will give you instant access to your emails. Most mobile phones come with an inbuilt email client so you may well already be using such a client when you access your emails on your mobile phone. But it's also simple to install an email client on a computer and use it there.
