**TL;DR:** Protect API keys, encrypt session files, restrict admin commands, validate payments server-side, and run bots in isolated containers.

Telegram bots often handle payments, user data, and admin privileges. A single leaked API key or session file can compromise your entire operation.

## Secrets and credentials

- Store API keys and bot tokens in environment variables — never in Git

- Rotate tokens immediately if a developer leaves or a repo was exposed

- Use separate bots for staging and production

- Restrict admin commands to verified user IDs only

## Session file protection

Pyrogram and Telethon session files grant full account access. Encrypt at rest, restrict file permissions, and back up securely — never share via Telegram or email.

## Payment security

- Validate transaction amounts server-side before confirming orders

- Reject duplicate payment references automatically

- Log every admin approve/reject action with timestamp

- Never store full card numbers — mobile banking uses reference IDs only

## Infrastructure

Run bots in isolated containers, keep OS packages updated, and use HTTPS for any webhook or dashboard endpoints. BDBOTS [managed hosting](/services/bot-hosting) includes hardened defaults.
