Allow Password Creation for Accounts Created with Google/GitHub Auth

If a person login to the application using Google first, no password is saved in the database. If then the same person try to register/login with email/password the application find the existing user by email and will try to compare the hash password, however the current one on the database is `nil` which break the password check:


We can not update the password when the user login as it will allow anyone to set the password for this user.
My idea is to send an `reset` email to the user when she can will be able to setup the new password via a specific link
