Slackにログインするのもメールにワンタイムコードを送ってくるようになってたよなあって思ったらタコベルのアカウントもパスワード無しにするとメールでお知らせが来ました。どこもかしこもSSOぽくなってメールのアカウントをちゃんと守らなくちゃいけなくなるのはちょっと怖いんだけど、それぞれのサービスとしては責任を減らせることになるんかなあ
> We're updating the way you sign into your Taco Bell Rewards account. Within the next week, you'll be asked to verify your email address when you log in to the Taco Bell app. You'll receive an email from us to this email address, which is tied to your Taco Bell Rewards account, asking you to click through to verify your email. Once your email address is verified, you'll no longer need a password to log in to your account. This new update is to enhance account security and make it even easier to place orders and earn points, redeem rewards, and access exclusive offers.
