Phone verification is an essential first step in your online relationship with a user. By verifying that a new registree on your website has the device, they claim in his or her possession (and the provided number is accurate) you reduce spam and fraud while signaling your concern for the user's security.

We've come up with some best practices and practical guidelines that can assist you while implementing phone verification. These best practices are also built into our Verify quickstart - we suggest running through it to see some implementation details.

Plan a User Registration Flow

Phone verification is an important first step when signing up a user, but should be considered holistically in your application's registration and usage flow. Checking that a phone number is legitimate, associated with a device, and in possession of a new registrant will cut down on spam sign-ups before you even grant a new user an account.

Suggested User Registration Flow

Our currently suggested signup and usage flow are as follows (only proceed to the next step if the previous step is successful):

現在Twilio社の推奨するサインアップおよび使用方法のフローは以下のとおりです (各項目の成功時のみ、次のステップに進みます) :

  1. Use Phone Verification to determine if the user has the device they claim currently in possession.
  2. お客との関係が今後も継続する場合:
    1. Register the user for continuous Two-factor Authentication usage.
    2. Twilioの二要素認証を必須とし、ログイン、高リスクな操作、および高額取引の任意の組み合わせについて保護します。
