Authenticator for Telegram

A Telegram Mini App for generating One-Time Passwords (OTP) for your 2FA-protected accounts.

Your data stays yours. All secrets are stored exclusively in Telegram's encrypted cloud storage. The app has no server, no database, no analytics — it never sees, collects, or transmits your data. The code is open source, so you can verify this yourself.

Available everywhere. Your codes are automatically synced across all your Telegram clients — mobile, desktop, and web. Wherever you have Telegram, you have your authenticator.
