Several people have recommended KeePassXC - Thanks - I have started using it and it is amazing. In addition to just storing passwords, it also does TOTP (Authenticator) and automatically pushes keys to an SSH-Agent.
KeePassXC is truly amazing, youcan find it on all possible operating systems, it can work fully portable or as appimage for linux, and there are nice browser extension to improve it.Browser extension is made by KeePassXC Team and it works great in both Firefox and chromium browsers and all their forks.
Note that it's better to keep TOTP Authenticator secrets in separate database from password.
So, in that same spirit I created a new bounty for KeePassXC.
Unless mistakes is made with somebody finding their backup keys, I doubt this will ever be broken and hacked, unless some major quantum change happens in future.I think this challenge will get very interesting as the price increases for all of these crypto's over the next couple of months 
Maybe you should post this challenge in social media like twitter to have more attention, if you didn't already do that. I would tag all three accounts for KeePass, lastpass and 1password, and maybe few bitcoiners and hackers like Kingpin aka Joe Grand.
