Why does Keychain plug my username in the email field?

I would ask why Keychain enters the wrong item in the email field in the first place, but I think it's just a BUG. It should be pretty obvious that the email goes into the email field. DUH.

When I originally signed up for the site, all the required data was entered into the correct fields, else the account creation wouldn't have gone through. If Keychain saved this data correctly, it should have associated PASSWORD with the password, EMAIL with the email, etc. Therefore, it should also re-enter the data into the correct fields.

I wish Apple would perfect the features it already has rather than introducing new features of dubious value.

I think I see part of the problem. I have THREE entries for Discord: two for discord.com and one for discord app.com (Safari > Preferences, Passwords).

One of the entries for discord.com has my username in the username field, and the other one has my email address. Discordapp also .com has my username in the username field (I'm not sure why it has a separate entry for discord app.com, since it shares the same password, but I will leave that alone).

This brings up a new problem: Why does it have a field for User Name and Password, but none for Email Address, since email address is what many sites require to log in?

Hmm, it seems Keychain is an inadequate password solution then, because some sites ask for the username to login, others ask for the email address.
