Can you provide some screenshots? How’s it working?

I’ve tried it. It works great.

I’m anxiously awaiting rclone release 1.64. It will add support for Proton Drive. Instant support on Mac & Linux.

I switched to 2FAS.

You can’t export from FreeOTP. Ente doesn’t appear to be open source. Tofu is an option but I’m afraid it might not be maintained.

Edit: Use Ente. It’s the best option.
