The other day, I got asked for my Gmail password, and then a page popped up that asked for all sorts of personal information.
"This is weird"
I immediately terminated the process, but the password had already been entered.
I could change my password, but now more than one or two machines have tied to my Gmail.
I thought my password had been stolen by this my mistake.
However, if my Google account is hijacked, I will be severely damaged.

So, this time, I hurriedly decided to add two-step verification to my Google login.
Two-step verification may sound like an ostentatious name, but in essence, it is a system that "Whenever my account is accessed from a new device (PC or smartphone), I can know the fact by voice or message of my home phone (smartphone).
This, psychologically, is quite reassuring.
If there's a login from other's device, the information comes to my phone. So I can immediately know the unauthorized access has occurred.
So far, there is no history of unauthorized access.
Even if you use "two-step verification", it's not perfect (I can imagine how to break this verification (in an old-fashioned analog way)).
-----
Of course, there are other methods of two-step verification besides the above, such as using a token system installed on your phone or a card-type token system to authenticate each time you log in.
This is the default method for financial matters (Bitcoin and online banking).
After my "unexpected death," I'm terribly worried about whether my wife and daughter will be able to get through this certification and get my money in order.
I made a manual, but there is a high probability that they will not be able to find it.

Incidentally,
In Bitcoin, an estimated 4 to 6 million BTC are in storage due to the loss of private keys (digital sequences).
The current conversion rate would be 24 trillion yen to 36 trillion yen.
With a hot wallet, if your private key in the cloud is stolen, you can easily lose all your money and
Even with a cold wallet, if the local hard disk crashes, you won't be able to get all your money out.
I think Bitcoin is scary in that aspect as well.
