But I can back up the secret in multiple places, and as another commenter mentioned, TOTP is an open spec, so I don't have to rely on exactly one sim card being in range of a cell tower. I have options.
My bank requires SMS confirmation every time I send money online, and when I was in the US for 10 days, even with my SIM, I couldn't get SMS's, and thus couldn't do banking. This is extremely annoying.
- cdubzzz 10y agoHow is TOTP being an open spec relevant? If $TOTP_APP does not work when you need it, it doesn't really matter. Even with a backed up secret. All I'm really saying is that limited options does not mean "broken". It just means limited options.
- heartsucker 10y agoIt's relevant because it means there are N apps out there instead of the exactly one pair of "my SIM" and "a tower my provider can use to reach my phone."
