This article seems to indicate that the ${oneTimePassword} variable is usable in the Registration - Activation email template. However, when I tried to use that variable, it does not render a value and simply remains ${oneTimePassword} in the email.
Is there a way to switch from magic links to e.g. a 6-digit OTP in the email? We are having issues with things like Microsoft Safe Links automatically accessing the magic link and inadvertently activating the user.
