If you registered using Google Sign-In, a password is not created automatically.
To fully manage your account, a password must be set manually.
This applies only if the account was created using the Sign in with Google option.
This also applies if a password reset is requested but no password was previously created.
To set a password, sign in to your account using Google Sign-In:
open your Account page
Scroll to the Personal Information section
Select Set a password, enter the new password, confirm it, and save the changes
After a password is set, login using email and password becomes available in addition to Google Sign-In.
Password reset emails will not work until a password has been created.
Setting a password is required to manage billing and security settings.
