Finding Succes And Fail Keychains

Maybe a stupid question, but I have problem with finding strings (that I can make keychains from) exclusive for invalid credentials and the valid ones in debugger log. Checked all the differences and there’s none excluding the randomized characters. I am not able to find anything static that I could use to create a keychain

Hi @bagniak in some cases valid response contains cookies you can use them as key
or response headers , or response code too if response body is empty .
