    User.where(email: data[:email]).first_or_create do |user|
        user.email = data[:info][:email]
        user.name = data[:info][:name]
        user.provider = data[:info][:provider]
        user.uid = data[:info][:uid]
        user.password_digest = data[:info][:password]
    end
end

Answer 1

Do not write the password_digest attribute directly. Use password (and probably password_confirmation) instead and Rails will do the magic for you.

Change

user.password_digest = data[:info][:password]

to

user.password              = data[:info][:password]
user.password_confirmation = data[:info][:password]

I advise to read the docs for has_secure_password.

Answer 2

The password is not being saved as a bcrypt hash.

From the bycrypt documentation

https://github.com/codahale/bcrypt-ruby

require 'bcrypt'

my_password = BCrypt::Password.create("my password")#=> "$2a$10$vI8aWBnW3fID.ZQ4/zo1G.q1lRps.9cGLcZEiGDMVr5yUP1KUOYTa"

my_password.version              #=> "2a"
my_password.cost                 #=> 10
my_password == "my password"     #=> true
my_password == "not my password" #=> false

my_password = BCrypt::Password.new("$2a$10$vI8aWBnW3fID.ZQ4/zo1G.q1lRps.9cGLcZEiGDMVr5yUP1KUOYTa")
my_password == "my password"     #=> true
my_password == "not my password" #=> false

So your code to store your user's password hash would look this

def self.from_auth(data)
  User.where(email: data[:email]).first_or_create do |user|
    user.email = data[:info][:email]
    user.name = data[:info][:name]
    user.provider = data[:info][:provider]
    user.uid = data[:info][:uid]
    user.password_digest = BCrypt::Password.create(data[:info][:password])
  end
end

Then you can test it like the documentation says http://api.rubyonrails.org/classes/ActiveModel/SecurePassword/ClassMethods.html
