Right, grabs helmet and ducks for cover, I use 1Password and it's not managed from the NAS. This might sound like an advert but it's just because I've used it for so long and had no issues (so far). I'd have looked at BW if I'd heard of it before and hadn't already got 1P setup with the family.
Prior to this I used SplahID on Palm OS and Mac, and it was a chore to keep synchronised. I migrated to 1Password after getting it in one of the software bundle sales about 10 years ago. Initially sync was local or WiFi to iOS, then I used via Dropbox (cos the 1P vaults were encrypted) and I could add items to a shared vault for my wife.
Since then I moved to the 1P family account (early sign-up got 7 users and 2GB storage) and now everyone has their own vault and we have shared vaults between my wife and me and each one of the kids, plus also a family vault ... helps to securely pass info since 'mum' is organised and manages us all
Don't use it just for passwords, all my software licences are in there and it's a TOTP app too.
We can still use local, WiFi and Dropbox within the various apps, if we don't want to use the 1Password cloud storage.
Cons:
- the mobile apps have limited locations for vaults: local to them (un-sync), Dropbox, 1P cloud.
- it uses a third party cloud, so trust is required ... though they are responsive to discuss their implementation and the security philiosophies behind
Pros:
- subscription includes access to all apps (inc browser plugins) for all platforms for all users... no excuses for not using it.
- price-wise it's similar to BW for what we use.
- works well on Mac and is pretty good on PC too.
- separate vaults for projects / whatever with access control.
The validation is that my family do use it, which isn't the case for everything I suggest!
