# MetaMask の使い方

{% hint style="warning" %}
**注意**

MetaMask は最も人気のある Web3 wallet です。そのため、オンライン詐欺、サイバー攻撃、ハッキングの標的になりやすいです。だからこそ、**seed phrase** を常に安全に保管しなければなりません。

ハッキングを防ぐため、MetaMask の seed phrase をコンピューターや携帯端末に保存し **ない** ことをおすすめします。最も推奨される方法は、seed phrase を物理的な紙に書き留め、その紙を自分だけがアクセスできる安全な場所に保管することです。

***Chiliz チームがパスワードや seed phrase を尋ねることは決してありません。***
