However, this feels more like having your sheep be herded by a fox...
Many here have already mentioned great points retorting this, so I won't beat a dead horse.
I will take the selfish opportunity to mention what my solution is that I'm working on: https://app.SrsPass.com
There's some rudimentary docs with a spec outline for those interested. But to sum it up, I share the same fears as others here of one device being some ultimate honey pot, or even worse, losing everything I have due to corruption or losing a/all devices where your pass vaults are when it comes to traditional managers. (Mind you, this coming from someone that runs RAID-Z3 NAS in multiple offsites).
Basically to keep it simple, I required the following aspects
- Available-source or Open-source (duh)
- Accessible on just about any device with a cpu, arm/x86 etc
- Vaultless & as stateless as possible
- No cloud, works completely offline
- Uses modern cryptography with sufficiently strong parameters
- Requires only one password to memorize
- Has uncrackable generated passwords (aka not feasible to crack in a long time period such as with 128 bits of entropy).
I believe SrsPass to meet all those aspects already. That is not to say that there aren't more features being worked on (the workboard is essentially public), however, I think you'd be hard pressed to find a more secure (when you build & run yourself) and accessible password manager than it.
