If you lose access to the phone number linked to your Telegram account, signing in with an SMS code can become a problem. A Passkey allows you to sign in without an SMS code using Face ID, fingerprint, a PIN, or another device authentication method.
What Is a Passkey in Telegram
A Passkey is a way to sign in to Telegram without a one-time SMS code. The key is stored on your device or in a password manager, while your identity is confirmed using biometrics, a PIN, or a password.
The main advantage of a Passkey is that you do not need to receive an SMS every time you sign in.
Where Is a Passkey Stored
A Passkey is stored in your device's secure storage or in a compatible password manager.
iPhone — in the Passwords app and iCloud Keychain when synchronization is enabled.
Android — in Google Password Manager or another supported storage service.
Windows and macOS — in a supported password manager or another compatible Passkey storage system.
How to Create a Passkey in Telegram
- Open Telegram.
- Go to Settings.

How to Sign In to Telegram Without an SMS Code
After creating a Passkey, you can use it to sign in to Telegram instead of an SMS code when Passkey login is available on your device.
- Open Telegram on the new device.
- Enter the phone number linked to your account.
- Choose to sign in with a Passkey.
- Confirm your identity using Face ID, fingerprint, PIN, or password.
- Complete the sign-in process.
Why Use a Passkey With a Virtual Number
If your Telegram account is registered with a virtual number, access to SMS may only be temporary. After the rental or activation period ends, it may no longer be possible to receive a new code on that number.
A Passkey allows you to save an additional login method in advance and reduces your dependence on SMS access.
Can a Passkey Replace SMS
Yes. A Passkey is designed to allow sign-in without an SMS code in supported login scenarios.
However, a Passkey does not remove or replace the phone number linked to your account. It is an additional authentication method.
What to Do If You Lose Your Device
If the Passkey was stored only on the lost device, your ability to sign in will depend on whether the key was synchronized with another device or password manager.
For this reason, it is better to store your Passkey in a synchronized storage service when this option is available.
How to Protect Telegram After Creating a Passkey
A Passkey does not eliminate the need for additional account protection.
Enable two-step verification, add current recovery methods, and regularly check your active Telegram sessions.
A Passkey can reduce your dependence on SMS codes, but the key itself should be protected as carefully as a password.
