The Windows Yubico program allows scraping of the desktop to insert totp 2fa's. I did so today.
They can also use WinAuth https://github.com/winauth/winauth
Or for Linux you can use https://github.com/paolostivanin/OTPClient

I like having TOTPs stored this way, as you can use them with any device, including over NFC on Android, just by installing the Authenticator app.
The desktop app will let you scan QR codes that appear on screen. When 2FA fields show up, the password autofill shortcut (cmd + \ is the default I think) will automatically populate them.
