Invalid key hash. The key hash does not match any stored key hashes.

[francisrod01]

I generate the key hash from android keystore following Facebook docs:

https://developers.facebook.com/docs/android/getting-started/#release-key-hash

So.. I implemented all of this lib needs to and I received this error message in my emulator:

The problem is that key hash is not my key hash generated and saved in the facebook developers app configurations.

I make a test: put this "new" key hash in facebook developers key hashes too and tried again and I was able to login successfully.

My doubt is: WTF's going on with this key hashes?
Please I need your help with this.

[nguyenvanphuc2203]

add key hash in message error to app setting 🗡️

[francisrod01]

The problem is that key hash is not my key hash generated and saved in the facebook developers app configurations.

This key hash it was add in facebook app settings but it is not my key hash.

[saimonventura]

I'm having the same problem.
As did what ma7modtaweelz talk about but the key was the same I get from the facebook mode.

if you can resolve this, plz post, I want to now to.

[saimonventura]

If your login is working without installing facebook app and not working when facebook app is installed due to error "hash key has not match" then do following steps

1 ) Launch your app and try to log in with facebook. A dialog will open and tell you: "the key has not been found in the facebook developer console and also show the hash key.

2 ) Note down that hash key.

3 ) Put it into your facebook developer console where you first generated your api key and remove the hash key with new and save. Now you are done. Anyone that downloads your app, published with earlier used keystore can log into facebook.

[delw]

@saimonventura what do you mean by step 3? I copied the key hash that the error was showing me and replaced it with the one in the facebook app but it still shows me the same error.

[francisrod01]

I make a test: put this "new" key hash in facebook developers key hashes too and tried again and I was able to login successfully.

The problem is that key hash is not my key hash generated and saved in the facebook developers app configurations.

@saimonventura Does you continues do use this hash key in your facebook developer as production? 0.o

This is a security fail and needs to be solved!

Firebase Facebook Login Hash Keys Issue

Hi, guys.
Regards from Colombia, I'm gonna ask you about this problem because today it was kicking my head.

I was working with firebase facebook auth into the react-native app, my problem is the same "key hash".

I thought this link should help me, but I did everything and the result is the same problem.
https://developers.facebook.com/docs/facebook-login/android/advanced

Another issue related:
https://goo.gl/Myd38Q

For this reason, I need to stay here as an active subscriber if anybody finds the solution, please reach out here.

this is my email: [email protected]

I will try to solve this problem.

SOLVED::::::

The solution just avoids closing facebook session, in develop when you will be in production this problem desapeears.

[francisrod01]

I think you guys didn't understand the bug here.

This is how to show up the hashkey:

~$ keytool -exportcert -alias my-key-alias -keystore my-release-key_pkcs12.keystore | openssl sha1 -binary | openssl base64
Enter keystore password: xxxxxxxx
xxxxxxxxxxxxxxxxxxxxxxxxxxxxx=

See more details: https://stackoverflow.com/a/7506445/3332734

Go to Facebook Developers and set the hash key to Settings > Basic - add Android platform and put the key in Key Hashes field and save it.

BUT the problem is to authenticate after this configuration.

In the RN the authentication returns error message containing the key hash yyyyyyyyyyyyyyyyy= does not match any stored key hashes.

I set the xxxxxxxxxxxxxxxxx= key hash in Facebook Developers, but returns me a error message with a yyyyyyyyyyyyyyyyy= key hash. I mean, a different key hash setted in FB Developers.

The thing that should be different here:

1 + 1 = 2 (mathematic)
1 + 1 = 10 (binary)

[bleedweedsuz]

i have the same error but when i didn't set any password in "Enter keystore password:" [here i just hit enter] then it works O.O
it give me some warning but it works (literally just now 😆 )

[ulrick]

I also had the same problem. I just emptied the cash and the app data on my phone after making sure to follow the whole procedure again

[ulrick]

it may also be necessary to add the key mentioned in your error in the "hash keys" field of the interface facebook for developper

[francisrod01]

I'm not use this lib anymore.
I'll try with a clean project this month.

[akyGit]

Please note, two types of key hashes exist: debug and release.

If you use react-native run-android: debug key hash will be used.
If you use ./gradlew assembleRelease and install app-release.apk: release key hash will be used

So, when you run keytool -exportcert -alias androiddebugkey -keystore ~/.android/debug.keystore | openssl sha1 -binary | openssl base64 you will see debug key hash

When you run keytool -exportcert -alias YOUR_RELEASE_KEY_ALIAS -keystore YOUR_RELEASE_KEY_PATH | openssl sha1 -binary | openssl base64 you will get release key hash

YOUR_RELEASE_KEY_ALIAS it's alias from gradle.properties (in most cases)
YOUR_RELEASE_KEY_PATH it's path to your release.keystore in your project (see gradle.properties file)

[madmax124]

After trying every possible solution (with no luck), downloaded a hash key extractor app : https://apkpure.com/key-hash-key/notimeforunch.keyhash

Copy pasted the hash key using the app and no more invalid hash key errors.

[nucklearproject]

If the hash code has be changed, try delete the app from facebook.

[yaibait]

@madmax124 thanks bro, your solution help me 💯

[edgargrs]

@madmax124 thanks,
before they close this error,
Someone can explain me why the application that provides @madmax124
generates a different keyhash than the one generated by the console.
To generate the keyhash of an apk that I have already signed is the following
keytool -list -printcert -jarfile [path_to_your_apk] | grep -Po "(? <= SHA1 :). *" | xxd -r -p | openssl base64
that command gives me a different keyhash than the one generated by this app

The keyhash generated by the application helped me and there were no problems with facebook, but who knows the difference?

[hoekeat]

but the point being, key hash is unique to devices, can someone confirm that is the nature of debug environment?

Solved mine too in Android Studio but with slight different approach.

To get the SHA-1 value in Android Studio.

1. Click Gradle
2. Click Signing Report
3. Copy SHA-1

4. went to website & Paste the SHA-1.
   Thanx ! Man !

[smileforandroid996]

@madmax124 thanks
can anyone know how this app work and get key hash ?

[RomuloDevelop]

I have the same issue today. Looks like it is an error of the openssl tool

[luatnd]

Exactly my issue, it ruins some of my hours.
My solution is "DO NOT USE PASSWORD" when you generating hashed key.

[pacozaa]

@bleedweedsuz man you just save me. It works!

[UzairAhmedSiddiqui]

extending @VickySalunkhe answer.
for anyone wondering where does new hash which your app complains about after being published comes from.

[MMujtabaRoohani]

Was facing the same issue. Just realized that I was generating Android App Bundle so the app signing was managed by Google Play Console. Just use the SHA1 fingerprint from Play Console under App Signing to generate base64 hash and it will work.

[LosYondris]

@MMujtabaRoohani Thank you very much, it has worked for me.

[jagmel]

Recently found this Hasher App which helps in extracting keyhash from sha1 (from google play store console) and vice-versa

[JosephineAkello]

I also had the same error, but I found two ways on how to solve it.

1. Add the key hash in the error message xxxxxxxxx= to the apps key hashes in facebook developers pagehttps://developers.facebook.com/, save then rerun the app.
   or
2. Find your sha-1 configuration by coping keytool -list -printcert -jarfile YOUR_APK_NAME.apk
   to your your terminal, then convert it to base 64 using http://tomeko.net/online_tools/hex_to_base64.php
   copy the key hash to your facebook developers account hashes, rerun the app and it will work.

Google play sign it if you use app bundle to release, so generate new hash key from signing key SHA 1 from google play store

Google play sign it if you use app bundle to release, so generate new hash key from signing key SHA 1 from google play store

@hafsalrahman elaborate please on how to to do it? i am facing the problem, the hash didn't match from facebook login error,

[limkokhole]

To get rid of tomeko.net site, you can simply use this shell command to get the same output:

echo -n aa:bb:xx | sed s/://g | xxd -pu -r | base64

[tomoima525]

@ariona Open PlayStore console -> App signing

Then copy SHA1

[iamabdulhaseeb]

The error doesnt show any hash key!

[chahalrohit]

if this message comes:
invalid key hash. The key hash **************** does not match any stored key hashes.
actually the key hash on screen is the correct key hash,
copy that key hash and paste it into facebook developers app id key hash section
if you use debug app than debug key hash work else if you use release build apk then release key hash work

[FetFrumos]

@madmax124 thank you. It is working. I entered it manually but got one character wrong. just copy.

[jomey-12]

I generate the key hash from android keystore following Facebook docs:

I make a test: put this "new" key hash in facebook developers key hashes too and tried again and I was able to login successfully.

While creating the hash key , the default password is 'android'. If you give any other passwords it wont show an error instead gives you a wrong hash key. That might be your problem.

[elaneri]

I just type the hash value into fc console XD

[russcarver]

Mine has had several lower case L and upper case I. It look forever to figure out, but after zooming in and comparing to their word "Invalid" in the error message, I was able to determine that lower case L are slightly taller than upper case I. The lower case L will go "above" the top of any capital letter. Upper case I will not.

[kcibdev]

Go to your google play console -> Setup -> App Intergrity
You will see a new key generated by google
use that in your facebook and console

[Abdo2021-a]

thank you so much :# @madmax124

Thanks bro, I tried many ways but this was a best way. Download "hash key app" and open it to generate a hash key by click your "project" icon in the srcreen. After that copy and paste in your facebook developer app settings.

[kunalnathinfotech]

I have just solved the issue of the invalid hash key issue

1. use the following code in terminal keytool -list -v -keystore ~/.android/debug.keystore -alias androiddebugkey -storepass anndroid -keypass android to generate the SHA1 key.
2. use the following website to generate keyhash: http://tomeko.net/online_tools/hex_to_base64.php
3. store the kehash in your app here: https://developers.facebook.com/apps
4. Don't forget to delete the keyhash you used which causes the issue.

[HossamBhi]

My issue was when i uploaded app to google play store there are a two App signing ( one is my release, second may be auto generated by google not my .debug ) in store.
You can find App siging in

Go to Google console => your project => Setup => App Integrity => App signing key certificate.

take your sha1 and convert it to key hash then add to key hashes in facebook app.
You can use this command to generate key hash.
echo {sha1} | xxd -r -p | openssl base64;

[JaySyntax]

If you are coming from flutter world, what i did was to set behavior to web only

loginBehavior: LoginBehavior.webOnly
