I really don't understand the point of these cloud password managers. Use something like KeepassX. Encrypt it with AES256, upload it to Dropbox, Google Drive, whatever. I personally throw the encrypted p/w file in an encrypted MacOS disk image with a secondary, separate memorized passphrase as well. Literally solves the problem without having to trust or pay some random sketchy service.
I create accounts quite often, so I would expect collisions to happen, the cost of mistake is high.
The other problem is that there is stuff you want for yourself, stuff shared with your partner, stuff shared with all the family (children included) and stuff shared 1-on-1 with each child.
