Create new random password

Hi,
I use PHP and MySQL within Dreamweaver
I want my client to be able to generate a new random password
for a new member.
How should I do this?
Create a list of random passwords or
can I create it on the fly while registering a new member?
I don't want the new member to create his own password.
Thanks to all people contributing to this forum.
I learned a lot here allready.
I hope you can also help me out with this one.

> can I create it on the fly while registering a new

That would be the best way.
I have used this to produce random, 8 character passwords
(the database part
is to make sure that they are unique) -
function randomkeys($length)
$pattern =
"234567890abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ";
for($i=0;$i<($length);$i++)
if(isset($key))
$key .= $pattern{rand(0,strlen($pattern)-1)};
else
$key = $pattern{rand(0,strlen($pattern)-1)};
return $key;
mysql_select_db($database_selectData, $selectData);
$query_rsPasswords = "SELECT contactPassword FROM
tblcontactdata";
$rsPasswords = mysql_query($query_rsPasswords, $selectData)
or
die(mysql_error());
$row_rsPasswords = mysql_fetch_assoc($rsPasswords);
$totalRows_rsPasswords = mysql_num_rows($rsPasswords);
$masterList=array();
$passwords=array();
$rsPasswordList = mysql_query("SELECT contactPassword FROM
tblcontactdata",$selectData)
or die(mysql_errno()." : ".mysql_error());
while ($rec = mysql_fetch_row($rsPasswordList)){
$passwords[] = $rec[0];
$unique = false;
while ($unique === false) {
$temp = randomkeys(8); // this is generating a random
8-character p/w
if(!in_array($temp, $passwords)) {
$newPassword = $temp;
$unique = true;

Pages created a random password for my document on my iPad. I have no idea what it is and I can't open my document. HELP!!!

How old is your son?
Under the Spanner in Pages there is Set Password where you create a password with hint. You really have to deliberately dig this out to do it.
Do you get a hint when you are asked for the password?
The Password is very secure, if you can't remember what it is, you will have to recreate the document.

After creating new accounts Password not accepted

On my daughter's G3 iMac (10.4.5) I have always had it set up with one user that was auto-logged in. Today I am trying to add 2 more users but the login window is rejecting the passwords. The set up for the users goes fine, but when the users try to log in their password is not accepted and the box shakes (nice touch btw).
My admin login still works fine. I also tried setting up those new accounts with no passwords, but they still get shaken off. Anyone have any ideas?
To make sure this wasn't user error on my part, I successfully set-up similar accounts on my iBook and they worked fine.
Thanks

sounds like a netinfo database issue to me. if you have applecare you could call to be sure. otherwise, you can rename your netinfo database (which has probably become corrupt) by booting to single user mode (apple+s on startup) and typing the following commands:
mv /var/db/netinfo/local.nidb /var/db/netinfo/local.nidb.bad
reboot
once you do that, the setup assistant will launch on reboot and to be sure you don't lose any of your daughter's data, make her user name, shortname and password are the exact same as they are now. after you've logged back in as her user, go ahead and try to re-create the users again. it should work. if not, you may be looking at an archive or possibly erase and install.
good luck! it may be a good idea to back everything up just in case!

Mac OSX 10.6.8 Cannot create new admin password. Have tried terminal. Password is lost or not recognized.

Have tried terminal. Password is lost or not recognized. I have tried using advice I found online. There is no disk to reboot. If I try to hold the C key it doesn't have a downward arrow it's up. I tried Terminal, doesn't recognize any commands. I'm fed up and tried using 24/7 paying them and for nothing. I cannot upload Maverick, not enough memory. Any other suggestions? I have more downloaded materials I'll try later but this is driving me nuts.

My camera is a 1Ds mk II..
and for that one it says
All versions tested. All versions tested. Supported only through Lightroom 4.1.
however, it also says
Windows XP, Vista, 7; Mac OS X 10.5 or 10.6
which is plain wrong, because Canon never supported any drivers for Windows Vista or Win 7, not to speak of XP 64bit. (You cannot connect the camera via firewire, without the device drivers!)

Random Password Generator

Hi everyone, I made this Password Generator that does what I want, but I'd like to extend its functionality. Right now it creates a random password from an array of letters and numbers.
import java.io.*;
import javax.swing.*;
import java.util.*;
*Version 0.1:
*creates several random passwords using numbers,
*uppercase and lowercase letters
*Version 0.2:
*add a save feature
public class PasswordGeneratorV02
    public static void main(String[] args)
         * Define all variables and create all objects here
        // create the Number and Letter arrays
        Integer[] numberList = new Integer[10];
        String[] letterList = new String[12];
        //Variable to continue the while loop
        Boolean cont = true;
        //Scanner used to continue or not
        Scanner input = new Scanner(System.in);
        //Stores the user input
        String answer;
         * End variables
        //fill the letterList array
        //need to find a more efficient way to do this
        //and add all the letters of the alphabet
        letterList[0] = "a";
        letterList[1] = "F";
        letterList[2] = "c";
        letterList[3] = "R";
        letterList[4] = "y";
        letterList[5] = "O";
        letterList[6] = "p";
        letterList[7] = "W";
        letterList[8] = "q";
        letterList[9] = "n";
        letterList[10]= "E";
        letterList[11]= "w";
        // fill it with numbers 0-9
        for (int i=0; i < numberList.length; i++)
            numberList= i;
// make both arrays lists so we can shuffle them
List list = Arrays.asList(numberList);
List list2 = Arrays.asList(letterList);
//Start the output to user
System.out.println("Welcome to the random password generator!");
System.out.println("This program will create a random 20 character alphanumeric password.");
System.out.println();
//Shuffles the array contents then prints it out.
while(cont == true)
// shuffle the list
Collections.shuffle(Arrays.asList(numberList));
Collections.shuffle(Arrays.asList(letterList));
// print out the shuffled array contents
for (int i : numberList)
System.out.print(i + letterList[i]);
System.out.println();
System.out.println("Press Enter for a new password. Q to quit.");
answer = input.nextLine();
//check to see if user wants to quit
if(answer.equalsIgnoreCase("q"))
cont = false;
System.out.println("Goodbye...");
}I would like to change/add two things.
1st, I want to change the array of letters to include the full alphabet(lower and uppercase), with out having to type it in.
2nd, I would like to add a save feature where the user types in "S" at the prompt and it will allow them to save the password as a text file.
Thanks in advance.

Ok well, I googled around and found something.
The output now displays letters, but it no longer shuffles them around. For example:
6A8B7C4D2E0F5G1H3I9J
Every letter is just the next letter in the alphabet. How would I shuffle an array of chars?

Random password generation

Hi All,
We have a link on login page "Forgot Password" ?
As users clicks the link, idea is he goes to page that has emails address and submit button.
As user enters his emails address and clicks submit, the mechanism gemerates a new password and sends it over to his email address.
My question is, "I dont know how to generate that new random password."
Is there a code around, that I can use ?
thanks a lot,
pp

It's easy enough to generate a random password. Use a
constant string containing your alphabet (different
systems have different rules about what characters
are allowed). Then us Random first to generate a
suitable length, then to pick a character from your
alphabet for each slot. If there are further rules
(e.g. "must contain at least one digit") then check
the password you've just generated and if it fails
the test, simply try again.
But this isn't a particularly good system. It allows
anyone to harrass a user by changing their password
if they can guess their user name.
The approach I favour is to send the user a one-time
click-thru URL in an e-mail which allows them to set
their password to anything they chose. That needs a
special table in some data base. You generate a
random token which acts as a one-shot password on a
special "change password" page. As soon as the click
through has been used then the database entry is
deleted so that the token is invalidated. You should
also invalidate the token if they log on in the
normal way.I agree that the 'forgot your password' feature is nasty. I mean, we are normally enjoined from saying "invalid user id" or "invalid password", we have to say "invalid user id / password combination" or something to that effect. But by providing the 'forgot your password' feature, it would be trivial to write a bot to see which sites provide this, determine a good page from a bad (e.g., valid user id) and then have an easier time brute-forcing the password. Sad.
On the other hand, I know personally that many companies are concerned with phishing attacks on their customers. As such, they have a blanket policy prohibiting any URL that hits a secured page in any way.
So, what to do? :^(

How to create a procedure to change randomly passwords

Hello,
I am trying to create a procedure to change randomly passwords for all users in a database. I need this after the database cloning. I have too many users to alter in a manual way...
Is there any option to create a procedure which will fetch all users in a database and alter them by a random password?
I was not able to find any clue.
Could you help me?
Thanks

Welcome to the forum.
change randomly passwords for all users in a database.All users? Including SYS/SYSTEM? I hope not...
But you could use DBMS_RANDOM.STRING and ALL_USERS and dynamic SQL.
http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14258/d_random.htm#sthref4675
http://download.oracle.com/docs/cd/B19306_01/server.102/b14237/statviews_2114.htm#REFRN20302
http://download.oracle.com/docs/cd/B19306_01/appdev.102/b14261/dynamic.htm#LNPLS01101
(easy to find when you do a quick search from http://www.oracle.com/pls/db102/homepage or http://www.oracle.com/pls/db112/homepage)
DBMS_RANDOM.STRING can give you a random password easily:
select dbms_random.string('x', 10)
from   dual
connect by level <= 10;Zo you could do something like:
begin
for rec in ( select t.username
               ,      dbms_random.string('x', 10) new_pass
               from   all_users t
              -- where t.username not in (...)
              -- or
              -- where t.username in (...)
loop
    --execute immediate ' alter user '||rec.username||' identified by '||rec.new_pass;
    dbms_output.put_line ('New password for user '||rec.username||' = '||rec.new_pass);
end loop;
end;
/You'll have to fill in the where-clause yourself/
I also commented out the dynamic alter user statement, since I'm not sure if you really want to reset the pwd's for all users.
Also, instead of using dbms_output.put_line to check the new passwords, you could insert them in a table or spool the output to a file.

When I attempt to send a text from the new iPad, a dialog box appears with the option to either sign in with Apple ID Password or Create New Account. I try signing in using my Apple ID password but IMessage informs me that email address cannot be verified

When I attempt to send a text from the new iPad, a dialog box appears with the option to either sign in with Apple ID Password or Create New Account. I try signing in using my Apple ID password but IMessage informs me that email address cannot be verified because it is already in use ??? What am I doing wrong?

settings -> iTunes & App Store
click on apple ID listed there
select Sign Out
sign in with the proper account
from then on, when the store ask for your password it should be with the correct ID

my friend gave me ipod touch with all his accounts, i created new accounts but when i went on the appstore and tried to update apps installed by him,i was asked his account's password! i dont know his password.how can i use my account to update apps?

You can't. Apps and really all content purchased/downloaded through one Apple ID is forever tied to that Apple ID. In the case of Apps they will always request that Apple ID to update as they are licensed to that Apple ID.
In reality, the Apps were licensed to that Apple ID by the developer. And cannot simply be given away to you for you to use.
He should have wiped the iPod clean so you could set it up for your use without any of his accounts or purchased content as you are not really licensed to any of those Apps.
Your friend should have followed this support document before giving the iPod to you:

Creating NEW CLIENT,USER and PASSWORD Please

Hi ..
I am having this problem ,I am from SD-module. I am trying to work with sending and receiving IDOC's . Here i have problem with creating another logical system.could u please assist me in creating another client/user/password on my existed system.so that i can be able to send an idoc from one logical system to another logical system.i would appreciate your efforts.
regards,
SURIYA.

Hi
You can create a client using transaction code SCC4. Then you need to perform a client copy, use transcation SCCL to perform a local client copy from client 000 using SAP_ALL/SAP_CUST profile.
Once you are done with you need to check whether the parameter login/no_automatic_user_sapstar is set to false (0). This can be achived in transaction code RZ10. You will have to restart the SAP server if the parameter value is altered(if not already 0).
Once the parameter is set then u can login to the client using user SAP* and password "pass". For performing client copy u will log into the destination client that is the client newly created and using SCCL perform the client copy.
Using BD54 u can create a logical system and in transaction SCC4 you can assign this logical system to the new client.
Once you are done with client copy then DDIC user will also be there with the master password given during installation time.
Using transaction SU01 you can create new users according to ur need and assign the roles/profiles as required.
Once this is done you can peform the IDOC sending and recieveing activity in between those clients.
If any more queries feel free to ask.

Have updated email add now passwords don't work and old email is still displayed so created new apple ID and password ,now app store still using old email /password .wat to do now

Have updated apple I D and password
Now appstores still using old apple Id and password
Cannot update or download apps
Created new apple I d and password and now still iTunes using old id and old password doesn't work
Bbaaaaaaaahhhhhhh

Hi Mofomon,
If you want to use the new/updated AppleID and password, you need to sign out of the App Store, sign out of iTunes, etc. and then sign back on with the new ID and password.
To sign out of the App Store on your iPad, go to Settings>iTunes & App Store, then click on your old AppleID, click on View Account, and sign in with your old password that goes with that ID. Then click on Sign Out. Once you have the old ID signed out, you can sign back on with the new ID and Password.
New purchases will be done with that ID, but if you actually set up a totally separate brand new ID from your old one (as opposed to simply changing it) then any past purchases will still be linked to that old ID, and will require the old password for updating.
If you simply changed your existing AppleID, then the new password will be what is needed for updating.
Cheers,
GB

Potentially the issue may be the combination of actual distance and the presence of any Wi-Fi interference at the location of the AirPort Express that may be the culprit here. The bottom line is you would want the Express to be within a 25+ dB range of the Extreme to be sure that it can consistently stay connected to it.

you haven't told us what "Park" the "merry-go-round" is in
tell us what actions you take to get Apple not to recognize your email address...
Are you formatting it correctly? - username @ someDomain .com <- NO Spaces (I did it so the system wouldn't make an email link out of it)
Tell us what happens when you realize that Apple is "not recognizing" your email. What message do you get, exactly? Take screenshot of the entire screen for context
