The HTTP Permissions-Policy header otp-credentials directive controls whether the current document is allowed to use the WebOTP API to request a one-time password (OTP) from a specially-formatted SMS message sent by the app's server, i.e., via navigator.credentials.get({otp: ..., ...}).

Specifically, where a defined policy blocks the use of this feature, the Promise returned by navigator.credentials.get({otp}) will reject with a SecurityError DOMException.
