Take a look at cryptocurrency security and see Part 1 if you need to.
Bitcoin security is important. Your bitcoin or any other cryptocurrency has a unique address or identification or private key. Therefore, you need to understand the importance of keeping it safe. If you lose it, it is difficult to restore it, so it is necessary to provide it as well as possible.
I must emphasize this openly, because security should be of paramount importance and should not be taken lightly.
There are countless stories of people who have lost access to their computers (as a result of carelessness or wrongdoing) and are ultimately unable to recover their bitcoins or other cryptocurrencies. This should be equivalent to putting your wallet in a vulnerable position due to pocketing or carelessness outside.
Fortunately, there is a way to double your assets. A secure device wallet, bitcoin, ethereum, litecoin, etc. in case you lose access to your computer or tablet, etc. will ensure that you have the ability to recover.
The hardware wallet allows you to recover your cryptocurrency on any other computer, as this is basically the USB connection you use to secure your transactions.
The vault is an original device wallet and bitcoin is easily set up for your security. There are other products, but for the rest of this article, I decided to deal with the Trezor device wallet first.
The basic principle of bitcoin security is one of zero trust.
Using the Vault screen, you can independently check and physically verify each operation directly on your device.
It also requires you to pin each time you log in. So you are always there.
As a single-purpose device, the wallet has no other functions.
Simple is equivalent to extra security.
The scanner does not exclude the risk of malware or viruses. However, the less the device is connected to the Vault, ie it is not possible to scan Bluetooth, wifi or QR code, so the simpler the communication protocol, the more secure your bitcoin security.
Also, the Vault does not have a battery. When disconnected from the power supply, it is turned off and your coins are safe from any cyber attack.
I hope I have emphasized the importance of bitcoin security. The key issues are zero reliability and concrete security. Also, make sure that your backup process is equally secure, that is, make sure that your information is openly accessible to someone you trust.
