FAQ

Answers to common questions

Account

How do I create an account?
Choose Create account on the sign-in page, fill in your details, accept the Terms, Privacy Policy, and Rules, and confirm with Telegram to finish.
Where do I update my profile?
Open your Profile from your account to edit your name, bio, and the details you share with connected apps.
How do I sign out everywhere?
Open Sessions in your account and choose Revoke others to end every session except the one you are using.

Security

What is Telegram 2FA?
When you sign in, we send an approval prompt to your linked Telegram. A login only completes after you approve it there, so a stolen password is not enough.
What are passkeys?
Passkeys let you sign in without a password using your device biometrics or a security key. Add one under Password & 2FA.
I lost access to my Telegram - what now?
Contact support to recover your account. You will be asked to verify your identity before any change is made.

Developers

How do I connect an app with OAuth?
Register an app from the developer dashboard, then use the authorization and token endpoints. The documentation page has the discovery endpoint and the full reference.
What is an API bearer token?
A long-lived token for server-to-server access. Request one under API bearers; an admin reviews each request before it is issued.
