Someone (like App Store reviewers) ask you for credentials to a service. You don't want to send them the seed and they wouldn't bother using it even if you did send it. You use this site to generate a link that will show the token. You share the link. Recipient can use it easily. The site has no idea who the seed belongs to, but you're smart enough to not use it for truly sensitive tokens. You're fulfilled with peace and happiness.
