To authenticate a user we deserialize the cookie and attempt finding the record in the database. If the attempt fails, we pass to another strategy handle the authentication.

# File lib/devise/strategies/rememberable.rb, line 19
def authenticate!
  resource = mapping.to.serialize_from_cookie(*remember_cookie)

  unless resource
    cookies.delete(remember_key)
    return pass
  end

  if validate(resource)
    success!(resource)
  end
end

A valid strategy for rememberable needs a remember token in the cookies.

# File lib/devise/strategies/rememberable.rb, line 11
def valid?
  @remember_cookie = nil
  remember_cookie.present?
end
