I have two ideas for you.
1.) Stop hiding PASSWORDS! I've used and paid for Roboform since about a year after they began. But somehow they've become less and less reliable every year. Sites come up, it doesn't even activate the password manager. I open roboform and scroll through the list. I see 7 different logins for the same page, unsure of which it actually is. choose. Wrong. Choose. Yep! OK Which was it? Oh. Do I wish to save this password? Sure although I know you won't display it next time. OR Sites with multiple logins like my Amazon, amazon S3, Amazon Business, etc which all have separate logins, all get listed and named the same thing without anything at all to differentiate them. So the site pops up. I now have multiple identical items to choose from. I KNOW I need to clean them up, but I don't have time, it continues to get worse, which means I would have to set even more time aside.
Then I stumbled across Dropbox passwords. And guess what? It just works! I don't have ANY of those problems. There are a number of sites that roboform doesn't even "see" and it sees them fine.
I don't even remember how I stumbled across it. I think I was just poking around the site. If you load the main site, it's nowhere to be found. If you go to the community, there isn't a category for it. Click on help center and it's not even in the submenus when you hover on anything. I can get to 3rd party integrations more easily than your own password manager which is more reliable than roboform!
I've already imported my passwords from roboform and I'm considering taking the money that I save from dropbox and using it to upgrade dropbox. My main concern however is - is it going to be a product that gets attention and development? Or was it a fluke that will soon die? I have no idea. There's no passwords thread that I can find. There are a few things that need to be done to take it from very good to great, but the foundation - it works - is there. The single thing that prevents me from disconnecting from roboform is that I'm not worried that they're going to disappear. They may figure out the issues they have soon enough. I suspect there is some underlying code or structure from the past that's difficult to break free of, similar to issues Windows had getting to 64 bit processing that requires a rewrite from the ground up to deal with the recent changes in browser security. I don't know. But I'm tired of waiting. Yet I don't want to move only to find out in January that Passwords is going away.
So if you're serious about it, bring it out front and center and show it off. Win over the large number of people with the same complaints I have on their boards and use your free password manager to bring on more dropbox users!
