I'm not using any lib right now

You're using AI to create the site, aren't you. You could ask it to look at the log in library and extract the parts you want, if tou don't want to use the full library itself, I guess. That'd be my solution. I'll be adapting thevlog in flow soon, for people creating accounts and I'll be incorporating elements from Amber to create BIP39 seed phrases into the account creation flow, while still using the rest of the library.

Good to know, thanks. I'm building a desktop client so I don't need it right now.

You're welcome - Plume is primarily also a desktop client but its definitely handy having the option there for people viewing on mobile...when it works.
