MetaMask Extension for Chrome | Official Website 

A well-known and well-respected browser extension, MetaMask Extension connects to the Ethereum blockchain and works as a cryptocurrency wallet. Users no longer need to download the whole blockchain onto their device in order to engage with the vast array of decentralized applications (Dapps) that inhabit the Ethereum ecosystem, thanks to MetaMask. 

For simple access to decentralized exchanges (DEX), gaming platforms, gambling websites, and many other apps, this makes it one of the greatest Ethereum wallet options available.

The most popular browsers, including Chrome, Firefox, Brave, and Microsoft Edge, are compatible with the wallet. In addition to holding ETH, the native currency of Ethereum, MetaMask also stores tokens based on the ERC-20 and ERC-721 specifications of the protocol.

First, only download MetaMask from the official app store for your device/OS. Don't download it from any other source. There are cloned copies of MetaMask that are designed to capture your Secret Recovery Phrase as soon as it is generated. Make sure you download the legitimate MetaMask app from the app store on your device and not from any other source to prevent falling for these scams.

1. iOS

• Click the search button on the lower right corner of the App Store. In the search bar, type MetaMask.

• To view additional information, press the app's name or select 'Get.' Complete the standard download confirmation process from the App Store.

• Open the program after installation, then build your wallet by following the instructions.

• Make a backup of your Secret Recovery Phrase offline and in a secure location!

2. Android

• Search for "MetaMask" in the Play Store after opening it. Make sure not to install a phony MetaMask app by using extreme caution! Choose the one with over 10 million downloads.

• Press "Install," then watch for the procedure to be completed.

• Open the program after installation, then build your wallet by following the instructions.

• Make a backup of your Secret Recovery Phrase offline and in a secure location!

With signatures, you may confirm that you are the original creator of a message or transaction by utilizing MetaMask. Using MetaMask, you can apply your signature to different tasks and manage your private key(s).

The saying "not your keys, not your crypto" may be familiar to you, and it's accurate. We merely need to pay close attention to the 'keys' portion in order to explain this idea entirely.

Your public and private key pair are the "keys." Each MetaMask account contains a pair of keys that, when used together, allow messages to be encrypted and decrypted.

When you send a message, the following happens:

• A lengthy hexadecimal number is produced when you 'hash' the message's contents. (The term 'hash' refers to the process of passing the message through a hash function, which reduces its contents to a fixed-size number.)

• You add your digital signature to the message by using your private key.

• After receiving your message, the recipient verifies it using your public key. They can confirm that you were the original sender of the communication because they utilized your matching key pair.

• That's the primary method; there's a lot of complexity involved, such as assuming that both parties are signing and verifying the signatures using the same techniques.

What is a Secret Recovery Phrase, and how do I back it up?

Most crypto wallets adhere to the convention of using a seed phrase, also known as a Secret Recovery Phrase. It gives you access to every account (address) in your wallet and is generated at random when you create a MetaMask wallet.

When you create your wallet for the first time, you get the 12-word Secret Recovery Phrase. On our servers, MetaMask has no control over any of your private or sensitive information. Everything is secured by your MetaMask password and encrypted in your browser. Therefore, you can only use your Secret Recovery Phrase to restore your MetaMask accounts in the event that you lose them.

In some cases, restoring your MetaMask wallet with your Secret Recovery Phrase also restores your MetaMask accounts. You will need to import accounts again if you have already imported them.

Don't share your Secret Recovery Phrase and private keys

Tokens can be sent out of your accounts by anyone who possesses your private keys or Secret Recovery Phrase. Never provide them to anyone, not even the MetaMask team or a representative purporting to be us.

We won't ever request your Secret Recovery Phrase from you. Insist on not sharing if someone says we do. Please report any suspicious activity by contacting Support if you come across someone posing as a MetaMask or MetaMask Support staff member and requesting your private keys and Secret Recovery Phrase.

This also holds true for apps and websites. You will only be required to submit your Secret Recovery Phrase in the following valid situations:

You have to enter specific words from the phrase to verify that you have recorded it when you are building your wallet for the first time.

If you reset your password (a similar process) or if you're recovering your wallet from a fresh install on a new device.
