Once I got good lesson from my former girlfriend. So I visited her and was need to show her some docs from my gmail mailbox. So I did it. Then I went home. In road I decided to check my mail notifications form social media. And so that one of them was opened. But I was sure that I didn't read it.
I started to think how it could happen. And then decided to look last actions in my account. And saw that last actions were at that time when I was in metro and even didn't touch my devices. Than I put 1 to 1 and remembered that I didn't log out from my gf's laptop.
When I came to her in next time I asked her to log out and to forget password.
So it was good lesson for me.
Since that time I don't use someone's laptops to enter to my account. And also always remind myself that I need to log out and keep my sensitive data in safety!!!
