Answer 1

Change your html code similar code below. (add another anchor to toggle password visibility, and add data-l attribute to the anchorss for using in js code):

window.onload=function(){
   var links=document.querySelectorAll("[data-l]");
   var pass=document.querySelector("#password");
   pass.addEventListener("keyup", function(){
        links.forEach(function(l){
            l.style.display= !!pass.value.trim().length==(l.getAttribute("data-l")=="true")?"":"none";
         })
   });
   document.querySelector("[data-l='true']").addEventListener("click", function(){
      pass.type=pass.type=="password"?"text":"password";
      this.innerHTML = pass.type=="text" ? "Hide Password" : "Show Password";
   });
};

<div class="input_field">
  <span>
         <i class="fa fa-lock" aria-hidden="true"></i>
  </span>
  <input type="password" class="password" id="password" name="password" placeholder="Password" maxlength="30" minlength="8" autocomplete="new-password"/>
   <a class="hyperlink link" data-l="false" href="forgot.com" id="link" style=" margin-right: 5px;position: absolute;top: 7px;right: 0px;" title="I forgotten my password" >Forgot?</a>
   <a class="hyperlink link" data-l="true" href="javascript:;" id="link" style="display:none;margin-right: 5px;position: absolute;top: 7px;right: 0px;" title="toggle password" >Show Password</a>
</div>

New part: If you want to show eye icon instead of anchor's text, you can use code below:

window.onload=function(){
    var links=document.querySelectorAll("[data-l]");
   var pass=document.querySelector("#password");
   pass.addEventListener("keyup", function(){
        links.forEach(function(l){
             l.style.display= !!pass.value.trim().length==(l.getAttribute("data-l")=="true")?"":"none";
         })
   });
   document.querySelector("[data-l='true']").addEventListener("click", function(){
       pass.type=pass.type=="password"?"text":"password";
       this.setAttribute("data-tp", pass.type=="text" ? "hide" : "show");
   });
};

[data-tp='hide']{
