serialize :params

def self.create_from_omniauth(params, user, provider)
    token_expires_at = params['credentials']['expires_at'] ? Time.at(params['credentials']['expires_at']).to_datetime : nil
    create(
            user: user,
            authentication_provider: provider,
            uid: params['uid'],
            token: params['credentials']['token'],
            token_expires_at: token_expires_at,
            params: params,
