Amazon Pinpoint now includes a one-time password (OTP) management feature. An OTP is an automatically generated string of characters that authenticates a user for a single login attempt or transaction. The OTP feature makes it easier to add OTP workflows to your application, site, or service. You can use this feature to generate new OTP codes and send them to your recipients as SMS text messages. Your applications can then call the Amazon Pinpoint API to validate that the OTP code the recipient entered is valid. 

When you use the OTP management feature, messages are sent with a pre-defined template. You can customize the brand name that appears in the message, the origination identity (such as a phone number or Sender ID) that is used to send the message, the length of the OTP code, the amount of time the code remains valid, and the number of allowed validation attempts. You can also select one of 12 different languages for the message body. To learn more about the OTP management feature, see Sending and validating one-time passwords (OTPs) in the Amazon Pinpoint User Guide.
