I’ve configured an Entra External ID tenant with user flows for sign-up and password reset. During both processes, users receive a one-time passcode (OTP) by email.

What is the default validity period of the OTP?

Can the OTP length and the validity be customized?

    The default validity period of the one-time passcode (OTP) in Microsoft Entra External ID is not explicitly mentioned in the provided context. However, it is indicated that the OTP can be customized, including aspects such as the length and validity period. To implement these customizations, you may need to utilize custom authentication extensions or configurations within your user flows.
