Let me lay out how my Telegram account was hacked. One night, I noticed an extra device had logged into my account. For security, I forced it to log out. The next day, when I logged into my account at work, I found I’d been logged out again. No matter how many times I entered the password, it kept saying it was wrong—and there was no hint I had set. That’s when I should’ve realized the two-step verification password had been changed. Not long after, I got forced out of both my phone and computer. Immediately, they changed my profile picture at lightning speed, bought a premium subscription, and deleted all my chat history. Now my account has been banned, and the UK giffgaff SIM card I originally used to bind the account has also been deactivated.

Sounds like something out of a fantasy novel.
How did he log into your account? And how did he know your password?
What’s the reason?
You didn’t enable two-factor authentication?
Looks like you really shouldn’t open unknown things—it’s dangerous.
Two-factor authentication wasn’t enabled! There might have been unusual activity long ago that went unnoticed!
If two-step verification is turned on, you probably won’t be able to log in.
How does it know your password?
Didn’t get it? Two-step verification has been changed.
Looks like it’s pretty much impossible to get this account back. You can try emailing [email protected] to appeal, and make sure to clearly explain what happened and provide early usage screenshots as evidence. But since the 2FA password has been changed and the account is already banned, the success rate is less than 20%. It’s a shame about the linked Google (gg) card.
One more thing: if you buy or start using a new account in the future, make sure to change your password within the first 24 hours, and clean up your devices after 24 hours. These are the two steps that 90% of people forget, and these two time windows are when it’s easiest to lose your account.

Even if you open it, it’s useless—you have to change the phone number to your own so you can receive the verification code yourself… 
2FA is very important
Enhance your own security awareness; enable two-factor authentication using your own email and phone number!
Is it really that amazing?
I feel like I registered the account myself, without any trading involved. The phone number is also linked to my own SIM card. I can just create another email to receive verification codes via SMS.
That way, I feel pretty secure. I don’t really need to set up 2FA either—after all, having to do 2FA every time I log in is kind of a hassle.
I don’t really understand how the other person is managing it—after all, you basically can’t log in without a common device.
