Not sure what you mean by a vault, but you have one ultra long password (think 10-20 word sentence) you enter every time you restart your computer (or when it times out if you prefer the extra security), and that opens the application where you store all your information. For the iPhone, you just need your fingerprint. It does have optional browser plugins to receive and inject password information, but they're completely optional to download/use. I use the plugins on all 3 browsers and have had no issues; I use the same concept of data important dictates password strength i.e. coinbase > banks > amazon > social media > etc.)
Example of what by 1pass looks like (I also love the different type of data that you can save and easily access, like my personal idendtity information):

Yes you can export stuff but I'm not sure what you would do with that export.
