Replace nextcloud login page with custom login page

Hello partners.
hello, thank you very much for answering.
I currently have a login developed in angular 10.
What I would like to do is replace the Nextcloud login page with my Angular login page. Would this be possible?
Or is it possible to use some method to authenticate me directly without using the login page? e.g loginviapost, oauth2 authentication, credentials in url.

Thank you so much

Hi, i donโ€™t understand the issue, more details please.

If you only need access from internet, you should enable https, and configure portforwarding in your router, not server, so you can access nextcloud from internet.
