I was wondering if it was possible to check user input from custom login screen (the login data are already created and saved in an entity) and authenticate while clicking on the login button. If the inputted values are true go to page1 or if not stay on same page with an error. My plan was to check the user input with the entity where the data is saved. I hope that I have expressed my question well

I have achieved this functionality using microflow. Please find an snapshot of a microflow. Here I am passing my student object to this microflow,I am checking the username and password in student object is already exist in database using loop.
Create a custom login form by using the tools provided in the modeler.
Set page 1 as the homepage for a userrole, authentication will provide the error message by default.
