How to Set Up & Use Passkeys in Telegram
Eliminate SMS login codes forever. Log into Telegram instantly using Touch ID, Face ID, Android Biometrics, or hardware security keys with zero phishing vulnerability.
Traditional SMS login codes are vulnerable to SIM swapping, cellular carrier intercepts, and roaming outages when traveling abroad. Telegram now supports industry-standard Passkeys built on FIDO2 and WebAuthn standards. By registering a passkey on your device, you can authenticate into Telegram in milliseconds using your fingerprint, facial recognition, or screen PIN—without ever needing a cellular verification text.
SIM Swap Proof
Cryptographic private keys remain locked inside your device's Secure Enclave. Even if an attacker clones your phone number, they cannot compromise your passkey.
Works 100% Offline
Log into new tablets, laptops, or secondary devices via QR code scan and passkey approval even when you have no active carrier roaming or cell coverage.
Password Manager Sync
Passkeys sync seamlessly across your personal ecosystem through Apple iCloud Keychain, Google Password Manager, 1Password, or Bitwarden.

Technical Protocol: MTProto Passkey Export & WebAuthn Ceremony
Telegram passkeys leverage the W3C WebAuthn standard integrated directly with MTProto authentication endpoints. During registration, the client generates an asymmetric ECDSA or Ed25519 keypair inside the hardware Secure Enclave and registers the public key with Telegram servers.
