secure

I would love a web based password manager that’s completely accessible on all of my devices. I know that there are a lot of tools out there already, and I know there are some inherent security risks with this approach, but here is what I’m thinking:

• It simply stores Title, URL, Username, Password, and maybe a notes section
• It’s web-based
• It’s secure
• It’s responsive so you can easily add information for any device you own*

I’m wondering if there is something out there already, if it’s a good idea, and if people think it’s worthwhile. What do you think?’

*This one is important. I have 3 computers, 2 tablets, and between 2-3 phones depending on what I need to test. I don’t want to buy or download an app every time.
