How does 2FA work on Lemmy? - Lemmy

When I try to add 2FA, I see the following in my settings, but clicking on it tries to open some external program through my browser: [https://lemmy.world/pictrs/image/a76d908e-359e-4339-b7bc-084f81d9ad1e.png] I just want to add an OTP through my 2FA app on my phone. Does lemmy not support this? How do I use what it does have? I saw this [https://github.com/LemmyNet/lemmy/issues/2363] issue on GitHub, which appears to say that 2FA was added, but I’m not sure if it is referring to this or something else.
