find out login parameters

[boyboy400]

Hello,
So I'm trying to figure out what the login parameters of this site are. These are the information that might help you:

This is the login page: https://aaaa.com/wp-login.php

and these are the lines from the source:

input type="text" name="log" id="user_login" class="input" value="" size="20" tabindex="10" /></label>
</p>
<p>
<label for="user_pass">pass<br />
<input type="password" name="pwd" id="user_pass" class="input" value="" size="20" tabindex="20" /></label>
</p>

In other words I'm looking for a URL that allows me to directly log into the account by only substituting the username and password. If it helps, I can give you the name of the site too. It's one of those blogging sites.
Thank you so much

PS. Long time ago I had a similar post but guess I didn't learn that very well sorry about that
PS2. The website is https BTW
