Telegram account risks (third-party client auth)

This applies when you connect a personal Telegram account to trip2g over the Telegram API (MTProto) — for publishing posts as yourself, importing channels, or letting an agent act through your account. It does not apply to bots created via @BotFather, which are safer (see the end).

The core risk

Telegram tightly polices accounts used through non-official (third-party / API) clients. If you generate too much activity in a short time — especially re-requesting the login code over and over — Telegram temporarily flags the account. After that, authorization through third-party clients stops working for a while: the login code silently never arrives, or the login fails. Your official apps keep working fine — only API logins are blocked.

We hit exactly this: repeated login attempts → the code stopped being delivered, and a fresh app_id/api_hash did not help, because the flag is on the phone number / account, not on the app.

What triggers it

  • Re-requesting the login code many times in a short window (the single most common cause).
  • Trying to log in rapidly from many IPs / data centers (e.g. switching servers between attempts).
  • Bulk/burst actions through the API — mass sends, fast loops.
  • Note: a new app_id/api_hash does not fix it if the number itself is flagged.

Symptoms

  • The login code does not arrive (no SMS, nothing in the Telegram service chat) — silently.
  • Login fails or returns FLOOD_WAIT with a wait time.
  • Actions get rejected. Duration is typically hours to a few days, occasionally longer.

How to avoid it

  • Request the login code once, then wait. Do not re-request it repeatedly — each retry can extend the block.
  • Use a number that already has an active official session (phone/desktop). For API logins Telegram delivers the code inside the Telegram app (the "Telegram" service chat), not by SMS — so an account with a live session gets the code reliably.
  • Don't switch servers/IPs between login attempts. Pick one place and stay.
  • Use a dedicated, warmed-up number; avoid bursty mass actions; respect FLOOD_WAIT — when Telegram asks you to wait N seconds, wait.
  • For publishing through an account, keep volumes sane (trip2g queues sends; don't blast hundreds at once).

If you're already flood-banned

Stop retrying — more attempts can lengthen the block. Wait (hours → days), then make a single attempt and check the Telegram app for the code. There is no way to force-lift a Telegram flood limit; only time does.

Safe fallback (no API auth needed)

To read or analyze your own chats without touching the API auth, use a Telegram Desktop export (Settings → Advanced → Export Telegram data, or per-chat Export chat history; choose JSON, no media). It's read-only and carries no risk to the account.

Bot vs. userbot

Posting via a Bot (BotFather token) is far safer and not subject to this login risk. Reserve the userbot (personal account over MTProto) for what genuinely needs it — posting as a real person, premium custom emoji, importing private history. When a bot can do the job, use the bot.
