Active Sessions
Every device and client that currently has access to the account.
Free Security Check
See who has access to your Telegram
The check pulls your account's security state into one result: which devices are authorized, where Two-Step Verification stands, and what access you have granted to outside services. It takes about a minute and runs inside Telegram.
Scope of the check
What the check covers
Only what the check actually reads.
Device details
The app, the time of login and last activity, and the region by IP.
2FA and Recovery Email
Whether Two-Step Verification is on and whether a recovery e-mail is set.
Connected access
Websites and services authorized through Telegram.
Assets at risk
The channels, chats and subscribers that would be exposed if you lost control.
Risk Score and priorities
One score for the account's state, plus the list of what to close first.
More than a list of devices. The session list in Telegram settings is raw data: rows with no interpretation. The check reads them against the state of your protection and your connected access, flags what looks risky, and hands you a clear next step instead of a puzzle to solve yourself.

FAQ
Questions and answers
How long does the check take?
The scan itself takes about a minute. Reading through the Risk Score and the recommendations takes a couple of minutes more.
Is the check free?
Yes. The account check and the Risk Score are entirely free and available in the Telegram Mini App.
Do you read my messages?
No. The check works with the account's security parameters — sessions, 2FA and connected access — not with the content of your chats.
What happens to the temporary access after the check?
The access granted for the scan is revocable: it is used for the analysis only and does not stay with us permanently.
What should I do after the check?
The Risk Score shows the priority actions. If you want continuous monitoring of new logins, move on to TG Cerber Continuous Protection.
