Delete all users from firebase auth console

Question

Is there an easy way to delete all registered users from firebase console? For example, I created a hundred users from my development environment, and now I want to delete all of them.

Update 2016-11-08 original answer below

We just released the Firebase Admin SDK, which supports administrative use-cases, such as deleting a user account without requiring that user to sign in first.

original answer

There is currently no API in Firebase Authentication to delete a user without requiring that user to sign in. We know this limits the usability of our API and are working to add such functionality in a future release. But as usual, we don't provide specific timelines for when the feature will be available.

For the moment your only work arounds are to:

• sign in as each test user in the app and delete the user from there
• delete each user in turn from the Firebase Console

Solution 2

As in updated answer, you can probably use firebase admin tools now, but if you don't want – here is a bit more solid javascript to remove users in the web:

var intervalId;

var clearFunction = function() {
  var size = $('[aria-label="Delete account"]').size()
  if (size == 0) {
    console.log("interval cleared")
    clearInterval(intervalId)
    return
  }
  var index = Math.floor(Math.random() * size)
  $('[aria-label="Delete account"]')[index].click();
  setTimeout(function () {
     $(".md-raised:contains(Delete)").click()
  }, 1000);
};

intervalId = setInterval(clearFunction, 300)

Just run it in developer tools

Solution 3

For the new Firebase update

Try this code for the latest Firebase update. Open the console, paste this code and hit enter!!!

setInterval(() => {
    document.getElementsByClassName('edit-account-button mat-focus-indicator mat-menu-trigger mat-icon-button mat-button-base')[0].click()
    let deleteButtonPosition = document.getElementsByClassName('mat-focus-indicator mat-menu-item ng-star-inserted').length - 1
    document.getElementsByClassName('mat-focus-indicator mat-menu-item ng-star-inserted')[deleteButtonPosition].click()
    document.getElementsByClassName('confirm-button mat-focus-indicator mat-raised-button mat-button-base mat-warn')[0].click()
}, 1000)

Solution 4

Because I'm pretty lazy at clicking buttons and elements in the UI, I set up a small client script:

$('[aria-label="Delete account"]').click()
setTimeout(function () {
   $(".md-raised:contains(Delete)").click()
}, 1000);

You may need to run it multiple times, but it is much better than wasting the time clicking things on the screen manually.

Solution 5

setInterval(() => {
  $('[aria-label="Delete account"]').first().click()
  setTimeout(()=>{
    $(".md-raised:contains(Delete)").click()
  }, 100)
}, 2000);

designed to avoid calling delete endpoint very often, since google fails with 404 error.

Can you please consider removing the 'Are you sure prompt' in the Firebase Console if you 'Shift' + click 'Delete account'. This would mimic the behaviour in the database and would significantly speed things up.

[krv]

Thanks a lot...works great..saves me 2 clicks and moving the mouse around :)

[makkasi]

Can I "sign in as each test user" from appengine , without browser? Can I delete users from app engine directly somehow or via some web services?

[Snewedon]

in the NodeJs firebase-admin SDK is there no way to get all users then for each user admin.auth().deleteUser(uid);

[Aldasa]

Is this right so far? "Löschen" = "Delete" "Konto löschen" = "Delete account" "Nutzermenü öffnen" = ?

[Luis Mejía F.]

Thanks, this is really helpful :)

[Ionică Bizău]

@LuisMejíaF. I expected it to be useful when posting the answer :) Always, automate the stuff when there's something repetitive to do :-)

[Mark Okhman]

yo, very useful bro)

[makkasi]

@Frank van Puffelen I see there is not python admin SDK. Is there some way to use the nodeJS admin SDK inside python.

[Thanh Truong]

Thanks, bro. Very helpful. :)

[mjpablo23]

how do i run this script?

[Ionică Bizău]

@mjpablo23 Open the browser developer tools (Right click on the page and Inspect or Inspect Element), then go to the Console tab and paste the code and press the return / enter key.

[mjpablo23]

what do I right click on? I'm on the Firebase->Authentication page in the Firebase console.

[Ionică Bizău]

@mjpablo23 Simply right click anywhere on the page.

[KrauseFx]

This works, however make sure to have the tab open not switch to a different one while it's running

[Drew Szurko]

Worked for me too. Thanks. It's sad this has to be the workaround.

[brs14ku]

Yes! Thank you. The delay was needed apparently.

[ashish]

How to delete only single user by uid?

[Yassine ElBadaoui]

You deserve a Nobel prize for this answer! 😜

[raiser00]

Am glad to know this is now possible via firebase admin sdk. Would be cool to know if these can also be uploaded and used as google https functions? TIA!

[Burhanuddin Rashid]

Please provide some explanation

[Sebastian Ortmann]

200 ms was short in my case. Set to 1000 - 1500 ms and it works!

[Eugene Hauptmann]

haha, thanks @AndroidRuntimeException , now someone should release an international version (seeing all those different languages above) and a version with official API, and this post will become ideal, lol

[Rethinavel]

I didn't even know that I could run Javascript in the console. Lessons learned. Learn the basics of other things too.

[Nguyen Thanh]

This script is better than the others!

[gbhall]

This was awesome to watch in action! Thank you to you.

[Eugene Hauptmann]

@gbhall ahahaha, glad you had fun with it.

[Jorsh]

This worked for me. I'm blocked right now tho, api didn't let me delete more about 8,000 users in

[Sunit Gautam]

Glad it worked. However, I did not face any blocking or restrictions when I tried it.

[Murtuza]

I had slow internet sow I had to put interval of 5000

[Eugene Hauptmann]

That's cool @Murtuza ideally it would be linked to the event handler when XHR requests are finished.

[howdoyouturnthison]

Thanks, but a few things I had to go add on. Required the addition of firebase-functions and also a private key to give the script credentials to run. Followed these steps: firebase.google.com/docs/admin/setup

[Soorya]

Thanks! you saved 342 clicks and 228 mouse moves 😆

[Daniel Fowler]

Confirmed this is still working in Jan. 2020. I was running anonymous users for about about a year, so now I'm using alternate browser to auto-click and delete 13,000 of them, 250 per page at a time (250 per page). THANKS!

[Chris]

I love this solution! I'm adding an if statement to count for the need to go to the next page though.

[Eugene Hauptmann]

hey @Chris, great to hear! Feel free to share your solution. Let's make firebase easier for us all :)

[Chris]

@www.eugenehp.tk posted :)

[Ayyappa]

When trying this script, set "Rows per page" to max and run.

[SuperUberDuper]

just dont let the general public have access to this

[SuperUberDuper]

why cant you tab away?

[ErraticFox]

@Aldasa "Open user menu" is Nutzermenü öffnen

[Narcis]

Brilliant solution, works like a charm! Thank you! 🙌🏽

[ZF007]

If you want to get possible rep for your answer then provide substantial more info to boos quality of your answer. 15 answer were before you...

[melchoir55]

Doesn't work for me. Just says 'interval cleared'

[AAverin]

I would suppose something changed in the UI of Firebase and script needs some updating. I wouldn't risk deleting my users at the moment, so if anyone will adjust the script for the changes, send me a message and I will update the answer.

[Henrique Bruno]

Nice. Here it complained about reaching the limit after ~100 removals, but just executed it again to finishing removing all. I recommend using .gitignore on the cred.json file.

[the korovay]

This works great, thanks! Just note: if there's an anonymous account in the list, change index in second 'getElementsByClassName' from 2 to 1. Also you can set shorter interval, i used 500.

[Reinis]

You are the best :). This works in 21.04.2021

[b.john]

how does this work>? where exactly do i write this code

[Yaman KATBY]

@b.john - Go to the auth page in your firebase console - Open the dev console in your browser - Paste this code and hit enter

[Yunus Yurtturk]

I made it working by changing 2nd command's index to 1, not 2 => document.getElementsByClassName('mat-focus-indicator mat-menu-item ng-star-inserted')[1].click()

[Vinasirajan Vilakshan]

This works for me 17.09.2021. For users authenticate by mail id's just use [2] in second line and others who use mobile authentication use [1] in second line.

[Tiger Abrodi]

THANK YOU, out of all the answers, this one worked perfectly, appreciate it!!!! <3

[Greg Sadetsky]

Still works as of Jan 7 2021. Thank you so much!

[Yaman KATBY]

@GregSadetsky 2022* 🤩

[Greg Sadetsky]

haha, you're right, 2022*!! I'll keep my original comment for posterity. :-) Cheers and best wishes

[Aezur]

That's some beautiful hackery. Still working 21 feb 2022.

[Ant1k]

Thanks. Crazy that this is still needed in 2022.

[Karol Be]

@Jorsh if you want ot avoid restrictions in my case simple timeout helped when calling getAllUsers again: setTimeout(() => { getAllUsers(listUsersResult.pageToken) }, 6000);
