That’s my problem with TOTP second factor authentication. I’ve used Authy for years because it works on Windows and mobile, but now they’ve decided they aren’t going to work on Windows anymore (but they still force update a perfectly working Windows app and there’s no way to opt out). I have no way to export my 30+ TOTP accounts to a new system. I often don’t want to have my phone around when I’m trying to focus and get work done, but now I have no choice. It’s infuriating. Is there any cross-platform TOTP system that has the ability to export your keys? Is that even a thing that’s technically feasible?
