If you've got anything in Authy that isn't using the authy custom authentication scheme (ie. just regular TOTP) now is the time to get it out.
Exporting the raw totp tokens can only be done from the desktop version that is currently deprecated and scheduled to be nuked from existence later this year. It requires getting the tokens loaded into the desktop app, then downgrading to an older version so you can use the chrome remote debugger to run a javascript function against the desktop app (embedded chromium) which pulls out the raw tokens and gives them to you.
