Thank you for submitting homework task-2 in Crypto-Academy.

To test the seed, I logged in the part that say restore, and entered the words from the seed, then the wallet was set up again without any problems. (I had to create a new password) The truth is that for a beginner like me, the procedures were quite simple.

That seed is known as Mnemonic key, which is a simplified version of the private key which are generally 12 words phrases (15, 18, 21, 24 words also). When you save your Mnemonic key, pay attention to the correct sequence of words, the correct sequence can only unlock your wallet.

Well the experience presented here with Atomic, Trust Wallet (both mnemonic key type and steemit's tron ​​wallet in which the key is sent as a private file once it is created.

You can also find the other forms of the private key(Mnemonic/Keystore file) of your Tron wallet, by clicking on "Export Account".

I think it is very important to have this secure element in the wallet, many times people put a password and trust that they will memorize it, having these keys allows to be aware of the importance of security and to keep them in a safe place, apart from its main security feature that would be to prevent anyone to duplicate our wallet knowing our key, or in case of theft or loss of the mobile device.

The best practice to secure your keys is to write it down on a notepad/piece of paper, better break it into 3/4 parts and keep them safe, off-line. Never take a screenshot, never try to store them in an email or cloud storage facilities. You can use a brand new Pen drive to store your keys. But always keep a hardcopy.

Thank you.
