Same here I'm logged in gmail from my mobile. I forgot my password and not able to access my gmail from any other device other than my mobile. Unfortunately I don't remember the secret questions also. Please help me in retrieving my password or changing my password.
Unfortunately, if, when you created the account, you have not registered a secret question which you remember, or an alternate recovery email address or phone number to which you have access to receive a reset code, you cannot prove that you are the account's legitimate owner. Hence account recovery is absolutely impossible and there is no way around it.
