It’s the perfect tool to manage your NFTs or interact with DeFi services (Decentalised Finance), smart contracts, and other dApps (Decentralised Applications).

With an intuitive interface, Metamask offers a simple yet easy to use interface for the best user experience with the so-called “Web3”, or the “Decentralised Web” 🆒.

In this article, we will explain how to use the Metamask extension to create and use a simple Ethereum wallet. The private keys will be stored on your personal computer within the browser data store.

❗️ Disclaimer ❗️ : private keys are needed to get acces to your wallet thus your Ether ($ETH). If you store your private keys on your personal computer, you have to be sure it is not compromised by a malware, a virus or something else…

In order to create your first software wallet, either you can import an existing seed, also called “Secret Recovery Phase” or create a new one.

Let’s create a new seed — a new Secret Recovery Phrase — by clicking “Create a Wallet”.

Metamask will ask you if you want to share some datas with the Metamask team to improve the usability and user experience of the product and the Ethereum ecosystem. It’s up to you to click on “I Agree” but as a newcomer, let just check “Not Thanks”.

Step 3— Set up a strong password

To secure the access of your software wallet, you must provide a strong password. Metamask won’t let you write a password with less than 8 chars but we strongly encourage you to setup a longer one.

Here are some example of good and strong password :

  • MySh@rK%Love8Eth&BTc/fork
  • G1ad2Se3Y0u!nTh3N3xtEvenT$
  • W3d0Lov3S@toCh!p$

Step 4 — Generate your Secret Backup Phrase

The Secret Backup Phrase is — in fact — the seed phrase. This is you very own and secret seed (or mnemotechnic passphrase). This is the only time the seed is shown to you ! Carefully write it down and store it in a safe place ! Along with the password previously setted up, the seed is the only thing you need in order to retrieve your wallet.

❗️ Disclaimer ❗️ : The seed is a mnemotechnic passphrase that will allow you to use your wallet, spend and retreive your funds. If you loose this phrase, you may loose your assets !

Step 5— Confirm your Secret Backup Phrase

As said previously, the seed or Secret Backup Phrase is shown once in your life and Metamask will ask you to confirm it to be sure you have write it down.

Congratulations, you have now a fully functionnal and ready to use Metamask software wallet. It will allow you to interract with the Ethereum blockchain and the Web3 applications such UniSwap, Rarible, OpenSea

Bravo ! You’re done… And ready to use your software wallet.


As you can see, Metamask is really easy to setup and can be resume as :

  • A password that will allow you to open your software wallet
  • A seedphrase that is the true ownership of your cryptocurrencies

Unfortunately the security of such wallet is strongly tied to your computer/network security. In the next article, we will show you how to improve the global security by using a hardware wallet with Metamask.
