@aasimali if you add a user without PW Joomla generates a random PW and send it via Email. Have a look into your emails.

thanks @zero-24

-I am reopening this issue because, There is an usability issue.
-While creating user from front-end all the fields are mandatory
-While creating user from back-end only 3 fields are mandatory!
-In this case, We should display a message 'an email is sent to your email ID containing password'

That's because in the backend an administrator creates a user and in the frontend it is the user itself. I don't see a usability issue here.

@rdeutz
Yes! But I am seeing! For example:
-You are a 'super user' of xyz site & you create an another super user, While creating super user, You
do not enter password & confirm password because they are not mandatory fields.
-Account is getting created and an email is also getting sent to the entered email ID, but who knows that? The only familiar user of Joomla knows! What about the new users?

I still think this isn't a big issue if any. On the other side it doesn't hurt if we have a message you are proposing. Can you make a PR?

When creating a user in back-end, the password and confirm password ARE mandatory, as far as I know (staging)

@infograf768
I also have the staging site and I updated the package yesterday! I need to check this current package. So,give me a minute please!

<input id="jform_password" class="validate-password required" type="password" aria-required="true" required="required" maxlength="99" size="30" autocomplete="off" value="" name="jform[password]">

@infograf768
I am sorry to say, but in the current package, it is not fixed. If it is fixed at your staging site, then, Its amazing.
I have downloaded & installed the package from here: http://developer.joomla.org/cms-packages/

hmm, weird

A clean staging install does the same as you show

Ok, I found out:

The password and confirm password fields become required when the Joomla User Plugin "Notification Mail to User" is set to No.

@infograf768 Hmmm! Yes, Its weird.
It might possible, someone has forgotten to commit the code. So, should I keep this issue open till it is not getting fixed in the package? Or should I close this?

@infograf768 Yes! It works. Thanks :)

@infograf768
Yes! It works. when 'notification mail to user' is set to 'NO'
-But if it set to 'Yes' Then, Can we display a message? 'User is created successfully and an email is sent to entered email ID containing password'

A message would be good indeed. In good English.

@infograf768 Yes! I agree

I am closing this because as explained it is not correct for these fields to be marked as required in this case

If someone wants to create a PR for the message as suggested please create a new PR
