I wasn't able to see any way to do even TOTP for PayPal when they insisted I enable SMS a few hours ago.
I don't have any money in there, it just mediates broken payment interfaces (e.g. Patreon rejected all my payment cards, from multiple banks apparently they're all fraud or something? No idea, the cards remain working no problem everywhere else, but I wanted to give people money for what they do, so I used Paypal to manage that)
It's pretty sad that in 2020 PayPal thinks SMS is a reasonable choice for protecting accounts that might actually have money in them...
