Metamask Wallet Setup and Security: A Step-by-Step Walkthrough

by Svein

MetaMask is a wallet that allows users to store, manage, and exchange their cryptos. Available as a browser extension, it offers simplified access to decentralized applications (dApps) and the Web3 ecosystem, thanks to an intuitive and user-friendly interface for securely managing your funds.

This tutorial will guide you step by step through installing and setting up your MetaMask wallet. You will then be ready to explore the world of Web3 and take advantage of innovative platforms like Kryll³ to maximize your crypto experiences.

1) Go to the MetaMask download page and download the extension on your favorite browser

2) Add the extension to your browser

Once the extension is added, you have the option to pin the extension to your toolbar:

3) Click on the "Create a new wallet" button

4) Choose whether or not you want to share your data with MetaMask to improve the wallet

4) Set a password

6) Carefully write down the recovery phrase (seed phrase) that MetaMask provides you on the screen on a physical medium

The seed phrase is like the code of a safe that allows you to regain access to your crypto wallet in case of lost access. You are entirely responsible for it, and if you lose this sequence of words, you will not be able to recover your wallet. Therefore, it is crucial to follow these simple rules:

  • Write down the seed phrase on a physical medium: Write the seed phrase on paper or a metal plate to protect it from damage. Store this medium in a secure place, safe from fire, flood, and theft.
  • Test the recovery phrase: After recording your seed phrase, test it to verify that you have copied it correctly and that it takes you to the same wallet with the same address.
  • Never take a photo of the seed phrase: Photos can be stolen or retrieved by malicious software. Keeping a digital copy of the seed phrase is risky.
  • Do not store the seed phrase in a password manager: Even if password managers are generally secure, they are not immune to security flaws. Keeping a digital copy of the seed phrase is risky.
  • Never share the seed phrase and never enter it on unverified websites: The seed phrase is confidential. Never share it with anyone, even if the person claims to work for a wallet or exchange platform's customer service. Only use official and reputable websites and applications to manage your wallet.

12) Fill in 3 of the missing words among the 12 words that were given to you previously

Congratulations! You have now successfully set up a MetaMask wallet and secured it with a well-protected seed phrase, ensuring the safety of your funds. You are now ready to dive into the crypto universe and explore the Web3 ecosystem!
