We use Authy for 2FA, which allows you to share keys across phones, so we both have 2FA for each others accounts.Before the age of multi-factor authentication schemes, it was easy to enable both my wife and I to have concurrent, unrestricted abilities on each other's financial accounts. But now there are things that make that harder:
* Using one cell phone number as an SMS second factor
* "Your voice is your password" voice print technology
Before, when trying online access, I could log in as her with user ID password, and complete the email loop (as long as I had the email in the profile configured with one I could get into), or with voice access, I'd just say I was her (they didn't ask about a male sounding voice).
Now, I'm running into more issues, and having to have a realtime exchange of SMS codes or drag my wife down into my office when I'm trying to do some things.
How do you manage this? I haven't tried to add myself to her account as a full access user because I figured I'd be limited. Has that worked for you? Which financial institutions? Was it / is it easy? Any "gotchas"?
Where SMS is still used, we have a shared google voice phone number.
