Sharepoint: Page Login

[LNeaga]

Hi All,

I have a question regarding Sharepoint Online.

Is there any possibility to create a page in Sharepoint Online where customers can login with user name and password, upload or download documents? We need a page for each customer, like an account, through we can communicate with them.

In this page we should have separate sections: upload / download documents, payment information, news.

Thank you!

No, it's not possible. Login into SPO is done through Office 365 Login page that in the end is powered by Azure AD

Since login is done through the page provided by MS only, it is not possible to create a custom login page.

However, after the logging in, you can toggle controls/redirect users based on the permission.
Also, you can achieve this using custom code in Application Customizer for Modern Pages.
