1. Open Terminal
  2. Paste Below Command (Step 3) And Hit Return
  3. keytool -exportcert -alias androiddebugkey -keystore ~/.android/debug.keystore | openssl sha1 -binary | openssl base64
  4. Enter Password : Android
  5. It will give you Key hash (like MibyjIEJWghOLquRdk9esClXHWH=)
  6. This will give you a debug key hash. Also we can generate a Release key hash with the same Process. Just need to change our keystore path and password.

Happy Coding. Thank You
