🔑Adding your SHA-1 Key

if you did NOT add your SHA-1 Key you will face some errors while verifying Phone Number

1. go to Android Studio > Build > Generate Signed APK > (choose APK if prompted) > then create a New Key and fill in the needed information.

you can skip step 1 if you already have .jks key.

1. after getting your jks key open the folder Firebase Console - Files\Generate SHA1 Fingerprint Tool then choose your OS type (x86 or x64) and open the file release.bat (make sure that you have Java JDK Installed)

2. it will ask you for key alias that you have set when generating the .jks key

if you did not define key alias the default key alias would be key0

1. you have to either type the key path like: D:\Folder\key.jks or simply drag and drop it

2. then you have to enter the key passowrd that you have set for the key ,the tool will show nothing as you type to make it more secure.

finally hit enter and you will get the SHA1 Fingerprint like this

Please make sure that you got SHA-1 NOT SHA-256, if for some reason you've got SHA-256, search for 'keytool' in Java directory and execute the command:

keytool -list -v -keystore <your_keystore_jks_file_path> -alias <your_alias_name>

copy the SHA1 key and go to your Firebase Project Console and click on little Gear icon > Project Settings >General

scroll down and you will find your package name, click on Add Fingerprint and paste in the SHA1 key that you've copied before. then click save
