Set a username and password for arduino from webserver and write it in EEPROM

Hello everyone,

I am trying to make a setup webserver with a form to enter variables that I will use in another part of the code, I got a code in internet and from there I managed to modify it to enter the ip that I will use, the problem is in receiving the user and the password, not I know how to write that part so that I can store the string or an array with the user and password, I have noticed that if I try to store characters the arduino stores them in their ascii number, sometimes I enter a d and the arduino stores a “100”, I would like to be able to send the user “admin” from the web and that is stored in the EEPROM that way, can you help me?
