Lots of regular people use Have I Been Pwned and sending them to 1Password is probably the single best thing you could do for them (I know it's a sponsorship - but it's a very complimentary one).

I'd make the language around that promo banner stronger (ie. "We strongly recommend") and make it stand out more on the page.

So many social media accounts get hacked[0] because of shared passwords and those affected users often end up on the site - funnelling them to a password manager and a reason why it's good hygiene is great.

ps. congrats on the relaunch!
