You manage security: KeePass
I use KeePass with a keyfile and password. The DB is stored and sync'd across devices in DropBox, I have my DB and key regularly backed up on a USB drive. The key is also present on some machines that I cannot easily add the USB to (eg. phone). It's the only password I need to remember -- I have literally hundreds (400+) of accounts. I do not regret it at all -- but it was a huge pain to migrate everything to it.
I also store my Google authenticator initial QR codes on it, in PNG format.
