Find my Phone with Google credentials

I used my Google credentials when I signed in to AirDroid. When I click on Find my Phone, I am asked for my AirDroid password. I don't have one of those. I tried to make an account and it said that email was already found. I couldn't even sign in here because of an error and had to use a different email address. Can somebody please help?

@rgordon Sorry for the late reply.An AirDroid account should be created when you sign in with Google for the first time, namely, the AirDroid account is your Google email. And a password for AirDroid account is supposed to set the time you created AirDroid account. Would you try to reset your password and try again?
