online password manager with sharing capabilities
I am looking for a good online password manager with the following requirements:
- Single click login from browser.
- Single click form saving from the browser.
- Not attached to a single PC.
- Offline version (so I can use it if there is no internet, for example plug USB and have last sync-ed data).
- Ability to store plain text (notes, for example).
- Should work on Windows, Linux and Mac.
So far I have been happy with RoboForm, but its offline USB version is not available on Linux.
