I don't remember my android debug.keystore password
Usually the debug.keystore password is just "android".
You can delete it and Eclipse will automatically generate a new one, as described here.
The Default Configuration of debug.keystore file:
Keystore name: "debug.keystore"Keystore password: "android"Key alias: "androiddebugkey"Key password: "android"CN: "CN=Android Debug,O=Android,C=US"where is this file located?
For Windows User: C:\Users \ [username]\ .android\debug.keystore
For Mac OS User: ~/.android/debug.keystore
After you will get SHAH1 by below command using Command Prompt:
keytool -list -v -keystore "C:\Users\username.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android
Note :above answer has just information of android studio default configuration to access debug.keystore(debug certificate) file you can make you custom certificate if you want you own password and configuration.
If you are not certain that the password has been set before, try just empty password. It worked for me.
