Putting in my 2 cents:
I use a Password Manager called
SafeInCloud.
I don't use its browser integration features, so I don't know how well those work. I chose it mainly because:
- the UI hits pretty close to having enough features for me to not feel hampered by it, but is simple enough to be easy to use
- there are versions for Windows (free) and the mobile devices I use, Android and iOS, (not free, but cheap). And they all sync without troubles.
- the synchronization uses generally available cloud services - it's not tied to a single vendor
Unfortunately, the synchronization configuration doesn't let me choose something under my own control (I've request support for SFTP, but there's no indication whether that ever got onto his radar). So for cloud and sync support, you need to choose between Google Drive, Dropbox, OneDrive or Yandex Disk.
While not precisely what I want, in my opinion this is far better than being dependent on a service that's run only by the software vendor. If nothing else, it gives an opportunity to migrate to another cloud service if the one you originally choose turns out to unacceptable or stops working for some reason beyond your control. Also, if the developer abandons the product, you still have some hope of it continuing to work.
