Why Docker Desktop?

• It can start urbit automatically in the background each time you login to windows
• Has a gui to turn urbit on/off if you don't want it running all the time
• Sets up port forwarding to your host device's ip, which plain wsl makes difficult. So you can access landscape from other devices on your lan, or forward ports to your router to get external access
• Automatic updates to the urbit binary

See https://subject.network/posts/urbit-windows-docker/ for an enhanced take on this guide, with screenshots and more.

Exporting your 2FA tokens from Authy to transfer them into another 2FA application

IMPORTANT - Update regarding deprecation of Authy desktop apps

Past August 2024, Authy stopped supported the desktop version of their apps:
See Authy is shutting down its desktop app | The 2FA app Authy will only be available on Android and iOS starting in August for details.

And indeed, after a while, Authy changed something in their backend which now prevents the old desktop app from logging in. If you are already logged in, then you are in luck, and you can follow the instructions below to export your tokens.

If you are not logged in anymore, but can find a backup of the necessary files, then restore those files, and re-install Authy 2.2.3 following the instructions below, and it should work as expected.
