but unfortunately the parameters in the URL (log/pass) are not accepted and OHAB asking me for login and password
How to configure URL to the page protected by log/pass?
There is nothing unusual about OH’s web frame card, so this is just a standard html question. Much of this is going to depend on the web page you are trying to log into, so you really are better off working through the support for that web page.
That said, html does not support setting user and password via query parameters, but if your page is using basic authentication, then it should support something like https://username:password@your.page.url
