PlayerInfo[playerid][Password] needs to be a string and

pawn Код:

PlayerInfo[playerid][Password] = dini_Get(pFile,"Password");

is correct, since passwords are strings, not integers (unless you can only have numbers for passwords on your server)

You can't do this

pawn Код:

new param = strval(params);

that will try and transform your string into a number and will always return 0, since you don't have any numbers in your password.
And since the same thing happens here

pawn Код:

PlayerInfo[playerid][Password] = dini_Int(pFile,"Password");

then both variables hold zero, which means every login will be correct.

Use strcmp for comparing strings
