Ad b2c custom policies - msverify otp sms message localization

Question

In AD B2C Custom policies, is there anyway to translate the msverify otp sms message that send to user mobile device.

This is the content of sms message:

"Use verification code [ some code ] for [ b2c tenant ] authentication"

I need to set a different content for this message, as in german my IOS device can not recognize the otp code then auto-fill code does not work.

This is TechnicalProfile in custom policy:

        <TechnicalProfile Id="GenerateOtp">
          <DisplayName>Generate one time password</DisplayName>
          <Protocol Name="Proprietary" Handler="Web.TPEngine.Providers.OneTimePasswordProtocolProvider, Web.TPEngine, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" />
          <Metadata>
            <Item Key="Operation">GenerateCode</Item>
            <Item Key="CodeExpirationInSeconds">1200</Item>
            <Item Key="CodeLength">6</Item>
            <Item Key="CharacterSet">0-9</Item>
            <Item Key="ReuseSameCode">true</Item>
            <Item Key="NumRetryAttempts">5</Item>
          </Metadata>
          <InputClaims>
            <InputClaim ClaimTypeReferenceId="email" PartnerClaimType="identifier" />
          </InputClaims>
          <OutputClaims>
            <OutputClaim ClaimTypeReferenceId="otp" PartnerClaimType="otpGenerated" />
          </OutputClaims>
        </TechnicalProfile>

I find here the localization specification from MS : https://learn.microsoft.com/en-us/azure/active-directory-b2c/localization-string-ids But I can not find the translation for sms message.

Hi @Nghia Tien Nguyen ,

Thanks for reaching out.

Unfortunately, Azure AD B2C localization do not provide SMS customization. However, it provides the capability to the use of a third-party SMS provider such as Twilio or your own custom SMS provider.

You can leverage DisplayControls and a third-party SMS provider which will help you to use your own contextualized SMS message, custom Phone Number, as well as support localization and custom one-time password (OTP) settings to your application.

Hope this will help.

Thanks,

Shweta
