Hi,

The "Customize Login Page Style" app on the Odoo apps store . We can configure the login page according to our needs. For this a new option is added in the general settings and based on that we can change the alignment of login to the left, right, middle or default. Also, there is an option to change the background of login page as image, url or color.

Here is link to the app:

You can use these apps (search apps in odoo apps by names provided below) to change the whole login page style.

Moreover, these apps provide the ability to define your own favicon and logo as you wish.

Minimalist Login Form

Creative Login Form

Hi, what changes do you want to make? If they are cosmetic changes you could create a module with a static/src/css folder with a css file that overrides the default stylesheet. You don't have to hack the source code.

The simplest way is to call /web/session/authenticate using JSON as follows:

{"jsonrpc": "2.0", "method": "call", "params": {"session_id": "SID", "context": {}, "login": "' + username + '", "password" : "' + password + '", "db" : "mydatabase"}, "id": null}

That is from a jquery function I created to handle authentication and the return value is the user ID. You'll have to retrieve the session ID from the cookie named sid to use in subsequent requests. If you use Firebug with the Net console active during a login it is very useful to see the entire process and the format of the JSON calls as well as the responses.
