Hello,
I have an issue how to solve a problem and make my project working.
First, I want to tell you that I do not start it yet because  I do not know where to start and how. I need guidance of what to read and where.
What I want:
With a brand new 8266, at power up, has to check a memory location (let’s say 50), and if it is empty, make a web page and ask me a password. This startup password is on the EEPROM at location 00. After I enter the original password, it has to change the web page and ask me to enter a new password TWICE. Then the new password will be recorded on EEPROM at location 10, and also write a 01 at memory 50. 
The second scenario, is if at power up, the location of EEPROM 50 has an 1. Then, you are presented with a web page where you put the password.
In the middle of the page, it is a black button. After you enter the password, you press the button like an ENTER button. If the password is OK, then the button turn GREEN, and an LED on the esp8266 PCB will turn ON. If the password is wrong, the button turn red, and after 30 seconds get black again and ask you to enter the password again. The LED, stay ON until power is removed from the esp board. This is my problem. If somebody wants to help me, I am wiling to pay for the work. If not, at least guide me what and where to read. You can write me directly at igeorge688@gmail.com, thank you.
