If its open a new tab you need to switch to that tab window before performing actions of that tab window.try below

  // this is to keep your parent window
 String parentWindow = driver.getWindowHandle();
 driver.findElement(By.linkText("Sign in")).click();
 Thread.sleep(3000);

 // since new tab is opened get new winodw handles and switch
 ArrayList<String> tabs = new ArrayList<String> (driver.getWindowHandles());        
 driver.switchTo().window(tabs.get(1));

driver.findElement(By.xpath("//input[@id='identifierId']")).sendKeys("abhi.abhib5");

Thread.sleep(2000);

// if you have further actions in parent window you need to switch back to the parent window
driver.close();
