Hello everyone! I am trying to start using KeePass DX on my phone and KeePass XC on my computer, and I am looking for a way to sync my passwords across devices. With Syncthing being discontinued for android, how should I sync the password database, so that changes made on any device are merged together?

I am considering Proton Drive, since it seems more secure for storing passwords than trying to use google drive, dropbox, or something similar. Is this a good idea, and if so how would it work? I have not been able to find much information about setting up Proton Drive to sync KeePass databases, so I don't know if it requires any special set up for everything to work correctly.

Once I have KeePass synced, how should I back up 2FA stored in either Aegis, or a separate KeePass database without losing the benefit of 2FA? Is it fine backing up 2FA using the same method I use to back up my passwords as long as they are in separate databases?

I need the setup to be sufficient for storing sensitive data that the average person has, like bank account info, and work reliably. Thanks.

    GrapheneOS The fork has major issues due to raising target API level without testing:

    Recommend using a different sync platform instead.

    They still seem to be running into problems with supporting Android 15, so I am worried that they may not be able to maintain the app properly in the future if they are a month behind now. Also, @GrapheneOS recommended against using it for these reasons, which is why I am looking for an alternative.

    I do it manually, in the same session as I run a backup on the computer. First USB cable to phone, copy across. Another possibility, if you have a secure cloud (I use Proton) is to upload to cloud, download to phone. Then do computer backup as per usual. It adds about 10 seconds to the whole thing.
