Yes, your idea is duly noted and valid - we could create a dedicated shared email address expressly for THS. We use individual email addresses.
But our viewpoint remains unchanged. We wonder what portion of THS couple members use joint email addresses. Or are willing to create one. Or are able to execute a workaround. We suspect that a high proportion of THS members will struggle and seek support.
We predict - perhaps wrongly - that by springtime then THS will have withdrawn its subpar 2FA implementation or significantly improved related functionality & customer experience. This is on the belief that THS may have saved $small on one-time software development costs but will spend $lots on ongoing remedial customer support. Very odd decision for a private equity backed organization. Against prevailing business culture of using great technology to reduce operational costs. Guess we’ll see.
For those interested, we have successfully circumvented THS 2FA with a workaround that uses a server-based rule on Apple iCloud+ to auto-forward emails related to THS 2FA. Rules needs to be on icloud.com rather than an email client, otherwise forward function requires email client to be open - which may be challenging given limited time of 2FA codes.
