[FEATURE REQUEST] Better login form

[frandj99]

Hi cheems, before everything I would like to thank you for this amazing version of GoIndex.

I would like to ask if it would be possible to get a better login form for the authentication.
I'm using Bitwarden as password manager (and probably I'm not the only one) and seems it has some problems with the pop-up in browser. It can't understand it's a form with a login so it can't neither auto-fill.
I guess it would be better if the form was inside the page, not as a pop-up.

All GoIndex fork have this issue, so I wonder if you could make a different login method.

Thanks in advance if you can help me :D
