I like your tool from a UX point of view, but nothing can fix the security issue that you use passwords created on a website which could at any time choose to store them.
PAAS (Password as a service) can and will never be a thing ;)
The security implications are all rubbish, and obviously it fails if the site goes away, but hear me out and then offer a local way of doing this, cause I'd love it:
Let's pretend you have some set of computer files that are distracting you. (A video game, or old high school/pre-divorce/estranged family photo albums, this could be anything). You want to keep them, but you want to restrict your own access to them.
Password as a service: you go to some little widget site, enter an email address, a date, and it gives you a password. Unless you have a photographic memory, you just paste it into a protected archive, forget it, and then wait until the date to get emailed a password reminder. Until then, you are locked out of your archive and there's nothing to be done until that day.
I haven't figured out a clever way of this that can't be defeated if the password is generated locally.
Browser refuses to load insecure font (that links using HTTP). You can replace "http://" with "//" so it can use HTTPS version while browsing via https.
