I don't think there's anything special about my account. It was a "personal" account when I created it, probably almost 15 years or so ago, then upgraded to a business account maybe 8-10 years ago.

I don't have my password handy right now so I can't login to check, but look for settings related to their "security key". I don't know if they still do or not but at one point they offered a hardware OTP generator (similar to the old RSA SecurID key fob) for a one-time $5 fee. Alternatively, you could use an existing one you already had just by entering its "ID number"; I used the IDs of my Symantec VIP Yubikey and also the app.

Sorry I can't be more specific or give you better guidance. I know that the option does exist, though; perhaps just explore the available options and maybe you'll stumble across it. Good luck!
