Oxwall does not have a default password. It is called masking. The dots are not values at all but just appear in the filed as a mask effect. There is nothing to reset.

What she is referring to is that if you tab to the field it will automatically highlight the mask, but if you click in the field the mask doesn't automatically highlight. On click you have to manually highlight the mask to remove it.

oh ok got it... thanks for clearing that up 

That is a password field so it is going to have the masking by default.  The click or tab issue is a js deal i believe and since i am not good with js i would have no idea how to do that. 

I always get this on my website. How to deal with it

not much you can do, that fields type is a password field as in.. 

<input type="password" blah blah blah..... 

And any password type field is going to have masking in it. Now that being said what you are seeing is a pre value of the masking because usually on normal pw fields the masking does not show up until after you type(as you type).  So that is what i was saying before is that its probably some javascript doing that pre load value.  And so it would be a custom code mod to change that. 

Actually it is designed that way to be more secure.  

Aditya, what is your software version? 

Since 1.8.3 version we changed such fields with the placeholders

See screenshot 1. 

When you start typing, the placeholder disappears. 

See screenshot 2. 

In your case, I believe this is auto fill of the browser. 

yeah i was trying to find where placeholder is set for the form but have not found it yet. 

Also there's a possibility that this is theme or plugin related. please do the testing with the default plugins and theme enabled only. 

I am using 1.8.3 and shifted to a default theme. The problem still persists.

Same thing here (oxwall website) when you sign you need to delete the dots.

You're right Ross it's the placeholder who do that because this problem does not appear in 1.8.2 with the same theme and plugins.

1.8.2 :
<div class="ow_password">

<input id="input_yj4ziqeh" class="invitation" type="password" value="password" name="password">

1.8.3 :
<div class="ow_password">

<input id="input_yn2lywug" type="password" value="password" placeholder="password" name="password">

I found half the solution but I don't know the consequences (security)

ow_system_plugins > base > bol > user_service.php :

    public function getSignInForm( $formName = 'sign-in', $submitDecorator = 'button' )
    {
        $form = new Form($formName);
 
        $username = new TextField('identity');
        $username->setRequired(true);
        $username->setHasInvitation(true);
        $username->setInvitation(OW::getLanguage()->text('base', 'component_sign_in_login_invitation'));
        $form->addElement($username);
 
        $password = new PasswordField('password');
        $password->setRequired(true);
        $password->setHasInvitation(true);  <- if false the next line will be disabled
        $password->setInvitation('password');  <- no language key here ! if empty ('') same result no more word and dots
        $form->addElement($password);
 
        $remeberMe = new CheckboxField('remember');
        $remeberMe->setLabel(OW::getLanguage()->text('base', 'sign_in_remember_me_label'));
        $remeberMe->setValue(true);
        $form->addElement($remeberMe);
 
        $submit = new Submit('submit', $submitDecorator);
        $submit->setValue(OW::getLanguage()->text('base', 'sign_in_submit_label'));
        $form->addElement($submit);
 
        return $form;
    }

Is it safe to do that ?

Yes! where do I find this default password and how do i delete it. Is it safe to do that?

I believe as long as the pw itself still shows the masking as you type the pw then i dont see a reason that it should be unsafe. However i have not tested this and anytime you edit the core there is always a chance you are taking. 

@Aditya   skaoxine posted the location it in his reply above

One last for the road ;-)

You can do something like that for example !
