Introducing the First Two-Factor Authentication (2FA) for TON Wallets

Tonkeeper Pro introduces a new feature that is new for all crypto wallets: on-chain second factor authentication for TON wallets with Telegram.

When 2FA is enabled, all transfers require two signatures: one from Tonkeeper and one from the Telegram bot. The bot sends a confirmation request to approve or cancel the transaction.

Why is it a big deal?

Instead of assuming users will do the impossible — safely storing their recovery keys in a vault — Tonkeeper acknowledges that many people keep them in notes apps, photo libraries, or even drawers. The nature of cryptographic material is such that once it’s leaked, it cannot be taken back. Tonkeeper’s 2FA acts as a safety belt for recovery phrase.
