Public OAuth information
L3 DC OTP Mailer is a dedicated email-delivery service for the private L3 DC Template. It sends a short-lived, one-time login code only to an individually entered work address that exactly matches the private approved-staff allowlist.
01
When an authorized user enters their approved work address, the service creates a six-digit code and sends it to that same address. Codes expire quickly, can be used only once, and bind the resulting session to the approved identity.
02
The Gmail integration cannot read messages, inspect contacts, access files, or deliver to an address outside the private allowlist. This public information site contains no login form and collects no form submissions.
03
The dedicated sender authorizes the narrow gmail.send permission so the private mailer can deliver authentication codes. Google authorization is completed only by the dedicated sender account.
Important
Operational users access the separate protected L3 DC Template. Never send passwords, verification codes, or operational information to the support address.
