Android : Typeface is changed when i apply password Type on EditText

The following might solve it for you.

pass.setTypeface(user.getTypeface());

Essentially it just passes the Typeface of your username field and passes it as the Typeface for your password field.

I found an explanation of this in the Dialogs API Guide.

Tip: By default, when you set an EditText element to use the
"textPassword" input type, the font family is set to monospace, so you
should change its font family to "sans-serif" so that both text fields
use a matching font style.

In otherwords, a fix that can be done in XML would be as follows:

<EditText
    android:id="@+id/password"
    android:inputType="textPassword"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:fontFamily="sans-serif"
    android:hint="@string/password"/>
