Sync between macOS and iOS devices with externally imposed limitations
I've been happily using 1Password for years, of late syncing between a few macOS computers and a few iOS devices with iCloud since Dropbox was banished by my employer (US government), but now they are also banning iCloud. The only cloud storage we are permitted to access that can be shared between my work Macs and those outside of my work network is Box, which is not supported for syncing by 1Password. If not for the iOS devices, I guess I would sync each 1Password to a local folder that I would sync between platforms using Box, but I can't see how I could tie into that method with iOS, though I'm unsure if the 1Password local folder sync would even play nicely with the Box sync. I'm a long-time Unix geek and am comfortable with such handy utilities such as rsync, but sadly the only Macs that are reliably connected to the internet 24/7 are inside my work network, so I'm rather stuck at present. Wondering if anyone knows how I might sync across my devices with these constraints.
