    Do you means that you want to save the username and password in the PIC?

    PIC16f877A has internal eeprom. you can save the passwd/username in the eeprom.

    May I know what is the output of DTMF generator? I never use it before:)

    Why its DTMF, of course :)

    Those touch tones you hear when dialing a landline telephone. Dual Tone Multi Frequency.

    You will need a DTMF decoder IC. That will "hear" the sounds and report them as a code you can use in the software.
