Can not change or update password because login via google account

I can not ssh to my jetson nano due to not having correct password. How to reset the password with google account login?

Are you talking about logging in using Google directly on the Jetson Nano using Google? As far as I know that is not a thing. You would have set up a user name and password on the OS for the Jetson. Usually you change those when setting up. Please refer to their documentation: Create connection to NVIDIA Jetson hardware - MATLAB jetson
If you are talking about your connection credentials using from one device to another when signing in to Remote.It, if you cannot sign in with your Google Auth and you had not yet created a user name and password signin for your account, create a new account with your Google email address and set a password. You will need to validate the account via email.
