Facebook Key Hash Does Not Match Any Stored Key Hashes

Facebook key hash does not match any stored key hashes

After hours of trying I've finally found a solution.

1. Delete any app on the website of Facebook (developers.facebook.com)
2. Delete the file debug.keystore under C:\Users\yourUserName\.android
3. Generate a new key (by running your app again)
4. Create a new app on developers.facebook.com and add the new hash key
5. Re-run your app
6. Succes!

The key hash does not match any stored key hashes in facebook react-native app

Try to use file in android/app/debug.keystore

cd <your project>

then

keytool -exportcert -alias androiddebugkey -keystore android/app/debug.keystore | openssl sha1 -binary | openssl base64

Android app Key Hash doesn't match any stored key hashes

Facebook some how replaces +,- and / with _

So just try replacing _ with +, - and / and add that hash-key.

Hopefully it should work.
