Electrum: There was a transaction that I did not do

[Vitboo]

A transaction appeared in my wallet, which I did not do.
Please, help to understand - is it a hack or a mistake?
What should I report?

[bauerj]

Well, did it send coins to you?

[Vitboo]

All coins are transferred to another address

[Vitboo]

Transaction is on the blockchain.info

either you've been robbed, or you are misinterpreting change addresses.
closing, because there's not enough information in your report to say anything else.

[Vitboo]

I will add the necessary information. Tell me what to add?
Here is one transaction that I did not do. And the purse was closed.

well, it looks like your bitcoins have been stolen.
if that is the case, there is nothing you can do, except learn to secure your wallet.

[Vitboo]

Please tell me what I did wrong - the password from the wallet is unique, not used or where. In the password of 19 different characters and was stored only in the head.
The computer was used only by me, there are no viruses on the computer.
Prompt please, in what there can be an error
Thanks in advance

either someone got access to your seed, or your computer was compromised.
the best way to prevent this is to use hardware wallets or two-factor authentication

Thank you very much for your help
Allow only one question - there were 35 addresses in the wallet. The receipt was always only for 4 of them.
After the withdrawal of money, these 4 addresses were lost from the address list.
One of my addresses- 1JauUnWnPZ34ZTW5t6FaLckRsc8xaEkr5J
And here on the screen in the list it is not

Please tell me why it happened, why did they disappear?
And where in Electrum two-factor authentication?
Can I cancel an unconfirmed transaction?
Sincerely, Vitalii

addresses were probably moved to the "used" section
no, you cannot cancel an unconfirmed transaction.

you need to create a new wallet if you want two-factor authentication.
I strongly suggest that you wait for the 2.9 release, because we are bringing some improvements there
(it will be this week)

[Vitboo]

Exactly, I forgot for two-factor authentication.
Thank you very much for your help and your time.
