FastCodeManager is a web platform (SaaS) for businesses that manage streaming service accounts for their own customers. It connects the mailboxes the business owns (Gmail, Outlook/Hotmail or custom-domain email via IMAP, and Telegram) and automatically finds the latest verification code or confirmation link (Netflix, Disney+, Max, Prime Video, Crunchyroll, Spotify and more). Each customer gets it instantly from a branded self-service portal and only sees what belongs to them, never the inbox or its password. It also includes customer management, a sales module to track renewals and expirations with ready-to-send WhatsApp messages, payments with Binance Pay, and an AI assistant inside the panel. Credentials are stored encrypted. FastCodeManager does not create, sell or obtain accounts: it only reads mailboxes the business owns or is authorized to use. Built for Spanish-speaking businesses in Latin America.
