It's called Time-based one-time password (TOTP), there are many apps for that, you don't have to use Aegis authenticator, although most apps like this are mobile need there are also some desktop programs for Windows and Linux available
Try wayDroid, it's an android container for running android apps on Linux. There's a way to enable arm emulation too
There is no need to emulate android. There are many good authenticators for Linux.
Use Authenticator by Gnome. It is best. You can also import from aegis
totp.app should work for your use case without the trouble of emulation. It's a web app instead of a mobile app.
