SMS is an absolutely unacceptable system to require for authentication. I just went overseas and got locked out of half the apps on my phone. Some of them permanently. Tinder now bans your account for life if you ever change phone numbers. I suppose if it's just one option then it's okay.

I think if you arent willing to fully lock yourself out if you lose your backup code, it should be a fallback that you can get a text, otherwise rely on a 2-factor app. Key would be that nobody in support should have any access to change your 2 factor number or disable 2 factor. Now if you lock down your account to just your backup code, no SMS, no take backsies.

> Tinder now bans your account for life if you ever change phone numbers Huh? I've got at least 5 different SIM cards for various countries and I've never noticed any issue with Tinder. I didn't even know it used your phone number for anything. For SMS auth it's usually no big deal to put back in your old SIM if it needs to send a 2FA code; even the most brutal roaming charges won't come to more than a dollar or so for a single SMS.

  > even the most brutal roaming charges won't come to more than a dollar or so for a single SMS Receiving SMS is generally free (or goes against your monthly bucket) while roaming. I’m actually not aware of any cell carriers (and I have SIM cards from over a dozen providers each in different countries) that charge for receiving anymore, but leaving a little wiggle room in my statement above just in case there’s an odd ball out there.

    Cruise ships: https://www.cruisecritic.com/articles.cfm?ID=1752 https://www.cruisecritic.com/articles.cfm?ID=1752 It's possible to send and receive text messages at sea, as long as you have a signal through your ship's roaming network (just make sure you turn off data roaming in your settings). Texting costs a lot less than a voice call -- usually in line with standard, international "pay as you go" rates: Most major carriers charge $0.50 to send a message ($0.25 for a picture or video message); AT&T also charges $1.30 for an outgoing picture or video message. For messages received, Verizon charges $0.05/text ($0.25 for a picture or video message), and Sprint charges $0.05, while T-Mobile and AT&T deduct incoming messages from your monthly allotment.
