Frankly, I'm glad Authy Desktop is dead. It didn't allow exporting of TOTP secrets, so migrating off of it was a pain. I've been much, much happier with a tiny shell alias to oathtool and gpg.
For extra benefit, bind a keyboard shortcut and use xsel (Linux) or pbcopy (Mac) to drop the TOTP code into the clipboard. Now entering a frequent TOTP code is as simple as two keyboard chords.
(I only do this because my employer offers very limited options for MFA and I don't have a smartphone. I'd much rather use the Yubikeys I already have...)
