Hello, in this post i will talk about a way of how to implement a Show/Hide password on Entry control. In our Xamarin.Forms project, we add  a CustomRender for iOS, and  for Android we are using a Effects in order of have a result almost equals. I'm gonna start with the iOS functionality, so I will add a class render: using System ; using Xamarin.Forms ; namespace ShowHidePasswordEntryXF { public class ShowHidePasswordEntry : Entry { public ShowHidePasswordEntry () { } public string EntryText { get ; set ; } } } After that, in the iOS project, i will create the renderer, in which I add a UIButton and add a EventHandler in order to know if the user want to look the password or not: buttonRect . TouchUpInside   +=   ( object   sender ,   EventArgs   e1 )   = >                  {                      if   ( Control . SecureTextEntry )                      {                          Control . SecureTextEntry   =   false ;

Add   ( " USA " ) ;              picker . Items . Add   ( " Mexico " ) ;              picker . Items . Add   ( " Brasil " ) ;              picker . Items .
