Protect Your Privacy by Choosing a More Secure Telegram Client
Telegram now officially supports Passkey authentication, so users no longer need to rely on SMS verification codes to protect their accounts. By enabling biometrics such as fingerprint or face recognition, users can establish stronger account protection. This new feature directly addresses security risks such as intercepted SMS codes and SIM card theft.
How Passkey Biometric Authentication Works
Passkeys use public-key cryptography to replace traditional passwords. When a user enables a Passkey in Telegram, the system generates a private key and a public key on the device. The private key is stored securely on the user's device and is never sent to Telegram's servers. The public key is uploaded to the server to verify login requests.
Unlike SMS verification codes, Passkey authentication is completed entirely on the device. Users prove their identity with a fingerprint, face recognition, or device PIN. This biometric data never leaves the user's device. Even if hackers intercept network traffic, they cannot obtain any usable authentication credentials.
The encryption used for biometric authentication follows the FIDO2 standard, an international security standard developed by the Fast Identity Online Alliance. It has been adopted by technology leaders such as Google, Apple, and Microsoft. Telegram's use of the FIDO2 standard means its security has been verified by leading security research organisations worldwide.
Complete Steps to Enable Passkey on Telegram
Enabling Passkey is straightforward. First, open the Telegram app and go to "Settings." Select "Privacy and Security," where you will see a new option called "Two-Step Verification" or "Login Security." Tap it, then select "Add Passkey."
The system will ask you to choose a verification method. If your device supports biometrics, you can choose fingerprint or face recognition. Some devices support only one of these methods, depending on their hardware. After this step, the system will ask you to complete a biometric check to confirm that you are the owner of that biometric data.
After verification succeeds, Passkey is activated. Starting with your next login, Telegram will first confirm your identity with an SMS code, then ask you to use biometrics to complete the final sign-in step. You can also choose in Settings to disable SMS codes and rely entirely on Passkey for authentication, but you must ensure that you can reliably access the device.
For existing login sessions, you can view all authorized devices under "Active Sessions." The system shows each device's login time, IP address, and location. If you find any suspicious login activity, you can remotely terminate that session immediately.
Advantages of biometric verification over SMS codes
SMS codes were once the standard way to protect account security, but they have several vulnerabilities. First, SMS messages travel over cellular networks, a channel that is vulnerable to man-in-the-middle attacks. Second, users may accidentally share a code with someone else or enter it over an insecure network. Third, SIM-swapping is a serious security threat: hackers can trick a carrier into issuing a duplicate SIM card for the target number.
Passkey eliminates these risks through biometric verification. Biometric features are unique: fingerprints are extremely difficult to duplicate, and face recognition uses three-dimensional depth sensors, making it similarly difficult to spoof. Biometric verification takes place on the user's device and does not rely on external communication channels. Even if a hacker obtains your Telegram account password or intercepts network packets, they cannot pass verification without the corresponding biometric data.
Passkey is also more convenient for users. There is no need to wait for an SMS or manually enter a numeric code; one fingerprint scan or face recognition is enough to sign in. For users who frequently switch between multiple devices, this quick verification method can significantly improve efficiency.
In addition, Passkeys support offline sign-in. Even if you temporarily cannot connect to a cellular network or Wi-Fi, you can still authenticate with a Passkey stored on your device, as long as you authorized that device previously. This is especially useful in airplane mode or areas with unstable signals.
Common Passkey authentication issues and solutions
A common question is: how can I access my account if my device is lost or damaged? This is a reasonable concern. Telegram generates a set of recovery codes when you enable a Passkey. Store these codes somewhere secure, such as in a password manager or on paper in a safe. If you lose your device, you can use the recovery codes to regain access to your account.
Another issue is how to handle biometric authentication failures. If a user's fingerprint cannot be recognized because of dry or worn skin, or facial recognition fails due to poor lighting, Telegram provides backup verification options. Users can authenticate with their device PIN, password, or the recovery codes mentioned earlier. This ensures they can still access their account if their primary biometric method temporarily fails.
Regarding device compatibility, not all devices support the same biometric methods. Older devices may support only fingerprint recognition, while newer devices may support both fingerprints and facial recognition. Telegram clearly indicates in Settings which biometric methods your device supports. If your device does not support any biometric technology, you can still use the traditional approach of two-step verification with a strong password.
Some users are concerned about synchronizing Passkey data. When you sign in on a new device, a Passkey must be generated again on that device. You cannot export a Passkey directly from one device to another. Each device has its own independent Passkey. This is intentional: even if one device is compromised, Passkeys on your other devices remain secure.
Layered strategies to improve Telegram account security
Enabling a Passkey is only the first step in protecting your account. To establish a truly layered security system, users should configure other safeguards as well. After enabling Two-Step Verification, signing in requires a custom passphrase in addition to the SMS verification code. Even if an attacker obtains your phone number and device, they cannot sign in without this passphrase.
Regularly checking Active Sessions is another important safeguard. In Settings, open the “Privacy and Security” section to see a list of all devices currently signed in. Each session shows the sign-in time, IP address, and device type. If you find any unfamiliar sign-in, log it out remotely immediately. This feature is particularly useful for detecting unauthorized account access.
Password management is equally important. If you set a passphrase for Telegram, make sure it is sufficiently complex. Use a combination of uppercase and lowercase letters, numbers, and special characters. Avoid using personal information such as birthdays, relatives’ names, or usernames as part of your password. Use a password manager such as 1Password or Bitwarden to generate and store strong passwords so you do not have to memorize them.
Privacy Settings should also be configured carefully. In the Telegram Privacy and Security menu, you can control who can see your phone number, last seen time, and profile picture. We recommend limiting the visibility of this information to strangers. You can also choose who can message you and add you to groups.
Use the Secret Chat feature for sensitive conversations. Secret Chats use end-to-end encryption, so even Telegram servers cannot read the message contents. Chat histories are not backed up to the cloud and exist only on the sender’s and recipient’s devices. Note that Secret Chats work only in one-to-one conversations and do not support groups.
For network security, avoid using Telegram to handle sensitive information on public Wi-Fi networks. If you must use it on a public network, encrypt all network traffic with a VPN service. Reputable VPN providers such as ProtonVPN or Mullvad VPN can help keep your online activity from being intercepted.
