i feel like deleting character should take more than just entering character name

I think that's a non-issue. I believe FFXIV doesn't allow for account sharing outside a minor child who's parent pays for the account.

We're talking a bannable offense here if you let someone else play on your account.

That's what I was referring to; there's technically no need for a secondary password check after login because we are prohibited from sharing our accounts. As someone else already suggested; if you happen to have a mischievous co-inhabitant, it would be best to lock the computer (assuming password protected windows/ios login) or logging out entirely if you need to step away.
