Sorry to jump in here. The "singular they" is the least awkward way of phrasing
this, i.e. "..inform the user that they can sign in..."

Don't be sorry. That's interesting! A good friend of mine told me about singular
they, but I never found an opportunity to use it. I guess now is the right time!
Thanks,
