The most common Authentication template — a one-time passcode for logging into an account, sent as a copy-code button message that many phones can auto-fill directly into the login field.

}Meta restricts Authentication templates to a fixed structure — a short body with the code, an expiry mention, and a COPY_CODE button — so there's less freedom to customize wording here than with Marketing/Utility templates. The {{n}} placeholders still map to real generated codes when sent through Lead Notifi.
