Signs of unauthorized access to your account
Understanding what exactly happened helps you choose the right protection strategy. Often users ignore the first alarm signals, considering them to be failures in the application. In fact, these are clear traces of third party activity on your system.
Pay attention to the behavior of the device. If your battery Samsung starts to drain faster than usual, and traffic is being consumed even in the background, this may indicate that hidden scripts are running. Hackers often use captured accounts for mining or sending botnet attacks, which creates a load on the processor.

Emergency blocking and restoration of access
The most effective way to stop an attacker is to intercept the session. Telegram is designed so that logging in from a new device breaks old connections, if you correctly confirm your identity, you will need physical access to the SIM card. registered to the account.
Try to log into the application again by entering your phone number. When an SMS with a code arrives, enter it. If the system reports that the code has been sent to another active chat, this means that the hacker is already inside. In this case, it is useless to wait for the SMS; you need to wait for the timer to expire and request the code via a voice call.

☑️ Emergency checklist recovery
Analysis of active sessions and devices
After restoring control, it is necessary to conduct a thorough revision. The menu Settings → Devices (or Privacy → Active sessions) displays the complete login history. Here you can see the device model, IP address and time of last activity.
Pay attention to unfamiliar locations. If you are in Moscowand logged in from an IP address in another country or even another city, this is a clear sign of compromise. Modern smartphones Samsung often display an approximate location, which helps identify the threat.
| Device type | Access status | Action |
|---|---|---|
| Your phone (Samsung) | Online | Leave |
| Unknown PC (Windows) | Was 2 minutes ago | End |
| Unknown iPhone | Was 1 hour ago | End |
| Telegram Web | Active | Finish |

What to do if you forgot your password 2FA?
If you have forgotten your two-factor authentication password and have not linked your email, the only option is to reset it, which will delete all secret chats and will take 7 days of waiting. During this time, you will not be able to use your account.
When installing 2FA, pay close attention to the prompt. It should not contain the password itself, but should remind you of the password. For example, if the password is associated with the date of birth of the pet, the hint may be “Name of the dog.”
This security measure makes your account virtually invulnerable to standard attacks. Even if hackers gain access to the SIM card, without a second password they will enter an empty shell.
