How to prevent a browser from storing passwords

Question

I need to stop browsers from storing the username  amp  password values  because I m working on a web application which contains more secure data  My client asked me to do this   I tried the autocomplete  off  attribute in the HTML form and password fields  But it is not working in the latest browsers like Chrome 55  Firefox 38   Internet nbsp Explorer nbsp 11  etc   What is the best solution for this

I solved this by adding autocomplete  quot one-time-code quot  to the password input  As per an HTML reference autocomplete  quot one-time-code quot  - a one-time code used for verifying user identity  It looks like the best fit for this

By default  there is not any proper answer to disable saving a password in your browser  But luckily there is a way around and it works in almost all the browsers   To achieve this  add a dummy input just before the actual input with autocomplete  off  and some custom styling to hide it and providing tabIndex   Some browsers   Chrome  autocomplete will fill in the first password input it finds  and the input before that  so with this trick it will only fill in an invisible input that doesn t matter              lt div className  password-input  gt               lt input               type  password                id  prevent autofill                autoComplete  off                style                    opacity   0                   position   absolute                   height   0                   width   0                   padding   0                   margin   0                                 tabIndex  -2                gt               lt input               type  password                autoComplete  off                className  password-input-box                placeholder  Password                onChange  e   gt  this handleChange e   password                  gt             lt  div gt

I just change the type attribute of the field password to hidden before the click event  document getElementById  quot password quot   setAttribute  quot type quot    quot hidden quot    document getElementById  quot save quot   click

I think it is not possible in the latest browsers   The only way you can do that is to take another hidden password field and use it for your logic after taking value from visible password field while submitting and put dummy string in visible password field   In this case the browser can store a dummy string instead of the actual password

I needed this a couple of years ago for a specific situation  Two people who know their network passwords access the same machine at the same time to sign a legal agreement   You don t want either password saved in that situation because saving a password is a legal issue  not a technical one where both the physical and temporal presence of both individuals is mandatory  Now  I ll agree that this is a rare situation to encounter  but such situations do exist and built-in password managers in web browsers are unhelpful   My technical solution to the above was to swap between password and text types and make the background color match the text color when the field is a plain text field  thereby continuing to hide the password   Browsers don t ask to save passwords that are stored in plain text fields   jQuery plugin   https   github com cubiclesoft php-flexforms-modules blob master password-manager jquery stoppasswordmanager js  Relevant source code from the above link    function        fn StopPasswordManager   function         return this each function             var  this     this             this addClass  no-print             this attr  data-background-color    this css  background-color              this css  background-color    this css  color              this attr  type    text             this attr  autocomplete    off              this focus function                  this attr  type    password                 this css  background-color    this attr  data-background-color                           this blur function                  this css  background-color    this css  color                  this attr  type    text                 this 0  selectionStart    this 0  selectionEnd                        this on  keydown   function e                if  e keyCode    13                                 this css  background-color    this css  color                      this attr  type    text                     this 0  selectionStart    this 0  selectionEnd                                        jQuery      Demo   https   barebonescms com demos admin pack admin php  Click  Add Entry  in the menu and then scroll to the bottom of the page to  Module  Stop Password Manager

I would create a session variable and randomize it  Then build the id and name values based on the session variable  Then on login interrogate the session var you created  if   isset   SESSION  autoMaskPassword            bytes   random bytes 16         SESSION  autoMask password     bin2hex  bytes       lt input type  quot password quot  name  quot  lt     SESSION  autoMaskPassword    gt  quot  placeholder  quot password quot  gt

I did it by setting the input field as  quot text quot   and catching and manipulating the input keys first activate a function to catch keys yourInputElement addEventListener  keydown   onInputPassword    the onInputPassword function is like this   assuming that you have the  quot password quot  variable defined somewhere  onInputPassword  event       let key   event key    event preventDefault       this is to prevent the key to reach the input field    if  key     quot Enter quot             here you put a call to the function that will do something with the password       else if  key     quot Backspace quot          if  password              remove the last character if any       yourInputElement value   yourInputElement value slice 0  -1         password   password slice 0  -1               else if   key  gt    0   amp  amp  key  lt    9       key  gt    A   amp  amp  key  lt    Z       key  gt    a   amp  amp  key  lt    z              show a fake     on input field and store the real password     yourInputElement value   yourInputElement value    quot   quot       password    key         so all alphanumeric keys will be added to the password  the  backspace  key will erase one character  the  enter  key will terminate  and any other keys will be ignored don t forget to call removeEventListener  keydown   onInputPassword  somewhere at the end

In such a situation  I populate the password field with some random characters just after the original password is retrieved by the internal JavaScript code  but just before the form submission  NOTE  The actual password is surely used for the next step by the form  The value is transferred to a hidden field first  See the code example  That way  when the browser s password manager saves the password  it is not really the password the user had given there  So the user thinks the password has been saved  when in fact some random stuff is what got saved  Over time  the user would know that he she can t trust the password manager to do the right job for that site  Now this can lead to a bad user experience  I know because the user may feel that the browser has indeed saved the password  But with adequate documentation  the user can be consoled  I feel this is the way one can fully be sure that the actual password entered by the user cannot be picked up by the browser and saved   lt form id  frm  action  quot https   google com quot  gt      Password   lt input type  quot password quot  id  quot pwd quot    gt       lt input type  hidden  id  hiddenpwd    gt       lt button onclick  subm    gt Submit this lt  button gt   lt  form gt    lt script gt      function subm             var actualpwd       pwd   val                hiddenpwd   val actualpwd                 Do whatever Ajax  etc  with this actual pwd               Or assign the value to another hidden field             pwd   val  globbedygook                frm   submit           lt  script gt

At the time this was posted  neither of the previous answers worked for me  This approach uses a visible password field to capture the password from the user and a hidden password field to pass the password to the server  The visible password field is blanked before the form is submitted  but not with a form submit event handler  see explanation on the next paragraph   This approach transfers the visible password field value to the hidden password field as soon as possible  without unnecessary overhead  and then wipes out the visible password field  If the user tabs back into the visible password field  the value is restored  It uses the placeholder to display     after the field was wiped out  I tried clearing the visible password field on the form onsubmit event  but the browser seems to be inspecting the values before the event handler and prompts the user to save the password  Actually  if the alert at the end of passwordchange is uncommented  the browser still prompts to save the password   x000D   x000D  function formsubmit e      document getElementById  form password   setAttribute  placeholder    password       function userinputfocus e        Just to make the browser mark the username field as required      like the password field does    e target value   e target value     function passwordfocus e      e target setAttribute  placeholder    password      e target setAttribute  required    required      e target value   document getElementById  password   value     function passwordkeydown e      if  e key      Enter         passwordchange e target          function passwordblur e      passwordchange e target      if  document getElementById  password   value               var placeholder                  for  i   0  i  lt  document getElementById  password   value length  i            placeholder   placeholder                         document getElementById  form password   setAttribute  placeholder   placeholder       else       document getElementById  form password   setAttribute  placeholder    password           function passwordchange password      if  password getAttribute  placeholder        password         if  password value                 password setAttribute  required    required          else         password removeAttribute  required          var placeholder              for  i   0  i  lt  password value length  i              placeholder   placeholder                           document getElementById  password   value   password value      password value              This alert will make the browser prompt for a password save       alert e type         x000D   form password not  placeholder  password     placeholder     color  red    change to black     opacity  1    x000D   lt form onsubmit  formsubmit event   action   action page php  gt   lt input type  hidden  id  password  name  password    gt    lt input type  text  id  username  name  username  required   autocomplete  off  placeholder  username    onfocus  userinputfocus event     gt   lt input type  password  id  form password  name  form password  required   autocomplete  off  placeholder  password    onfocus  passwordfocus event     onkeydown  passwordkeydown event     onblur  passwordblur event    gt   lt br   gt   lt input type  submit   gt  x000D   x000D   x000D

One thing you can do is ask your users to disable saving the password for your site  This can be done browser wide or origin wide  Something else you can do is to force the inputs to be empty after the page is loaded  and after the browser auto completed the fields   Put this script at the end of the  lt body gt  element  userIdInputElement value    quot  quot   userPasswordInputElement value    quot  quot

While the previous solutions are very correct  if you absolutely need the feature then you can mimic the situation with custom input using text-field and JavaScript   For secure usage  you can use any cryptography technique  So this way you will bypass the browser s password saving behavior   If you want to know more about the idea  we can discuss that on chat  But the gist is discussed in previous answers and you can get the idea

This is not possible in modern browsers  and for good reason  Modern browsers offer password managers  which enable users to use stronger passwords than they would usually  As explained by MDN  How to Turn Off Form Autocompletion   Modern browsers implement integrated password management  when the user enters a username and password for a site  the browser offers to remember it for the user  When the user visits the site again  the browser autofills the login fields with the stored values  Additionally  the browser enables the user to choose a master password that the browser will use to encrypt stored login details  Even without a master password  in-browser password management is generally seen as a net gain for security  Since users do not have to remember passwords that the browser stores for them  they are able to choose stronger passwords than they would otherwise  For this reason  many modern browsers do not support autocomplete  quot off quot  for login fields   If a site sets autocomplete  quot off quot  for a form  and the form includes username and password input fields  then the browser will still offer to remember this login  and if the user agrees  the browser will autofill those fields the next time the user visits the page   If a site sets autocomplete  quot off quot  for username and password input fields  then the browser will still offer to remember this login  and if the user agrees  the browser will autofill those fields the next time the user visits the page    This is the behavior in Firefox  since version 38   Google Chrome  since 34   and Internet Explorer  since version 11   If an author would like to prevent the autofilling of password fields in user management pages where a user can specify a new password for someone other than themself  autocomplete  quot new-password quot  should be specified  though support for this has not been implemented in all browsers yet

One way would be to generate random input names and work with them   This way  browsers will be presented with the new form each time and won t be able to pre-populate the input fields   If you provide us with some sample code  do you have a JavaScript single-page application  SPA  app or some server side rendering  I would be happy to help you in the implementation
