I have found my YubiKey quite nice for password sercurity, but I use it in a slightly different way. I use password-store, which is a git repository of GPG encrypted passwords. While I'm on my main laptop, which has Qubes, I can access passwords using a key stored in my keys vault using Qubes split GPG. Encrypted passwords are synced through SSH to my serwer. On my other computers, I can decrypt passwords with my YubiKey as a gpg smart card. This is probably way overcomplicated, but it works.

I am security conscious but not as conscious as jgc, I am doing the same with the database on the drive and the drive is encrypted. I have a "smaller" password in the head plus a Yubikey password which is appended to my smaller password. For each website I am using a randomly generated password.

What is important is that in my daily life, this is working perfectly well and I do not feel at all the annoyance of the added security against using the same dadada password on all the websites.

I really recommend a head stored + hardware generated password too, this is working wonderfully.

Sounds like a good system. Having something easy that you will actually use is the most important thing.

There is no one-size-fits-all solution and it should clearly depend on the threat model. I can imagine why someone who could be expected to have the keys to CloudFlare's infrastructure might want to take extra care.

Actually, I don't have the keys to CloudFlare's infrastructure. I don't have access to our production systems at all.

I thought this might be the case, but it doesn't stop people from believing you may be a high value target. So the good security practices are very prudent.

I suppose I'm even less security conscious, as I'm storing my file in ownCloud and sync it also to my Android. I assume this use case prevents using a Yubikey password for enhanced security?

You can always put your files in OwnCloud in a TrueCrypt container, and anything that's unlocked by a password can use a Yubikey password with head-stored additions.

I'm not aware of ready-made solutions to locally decrypt cloud-stored data on mobile phones though, I don't think you can mount TrueCrypt volumes on your phone. Anyone know of a way to do this?

Hetzner (Germany) has quite cheap storage. https://www.hetzner.de/de/hosting/storagebox/bx30

Based on the protocols they offer it is easy to mount encrypted. LUKS is available for Android (rooted) https://play.google.com/store/apps/details?id=com.nemesis2.l...

Does OwnCloud do the block-sync like Dropbox for TrueCrypt containers, or does it need to reupload the entire container if the container is modified?

Just had a look at KeePassX, as it looks as though it has a sleeker UX, when compared with KeePass2.

It may be considered a faux pas, but I have come to like the http plugin, for KeePass2, which allows Firefox to reach into my database when I come to sign into an online account.

do you have a backup yubikey? I'd be worried about losing mine and then losing all my data.

I printed a copy of the key, sealed it (and other stuff I wanted backed up) and give it to person that I trust to keep.
