Locked out in n2048 switch

Hi There,

I have Dell N2048 switches in stack configuration. I have changed the password by using below command:
"username admin password mypassword privilege 15 encrypted"

Now, I am not able to login with the new or old password. This is a dummy password in the above command.
I had found out later that encrypted keyword expected an encryption before entering it.

Is there a way to get encrypted password?

Thanks in advance!
