I use 1Password. To my non-security-expert eyes, the two weakest spots in how I use 1Password are: (a) The plugin I use on the browser, (b) The fact that I use Dropbox to sync the password keychain.
I can maybe move the keychain to an encfs encrypted folder in Dropbox. Then, I won't be able to use 1Password mobile app. And for the plugin, perhaps I can disable the plugin and copy-paste the password directly from the app.
Would love to get others' feedback. UPDATE: It appears I can combine sync through encfs folder and manual sync through phone to achieve sync on all devices.
