Welcome to this guide on securely setting up a MetaMask wallet. This guide focuses on the security choices you can make when setting up your MetaMask wallet; if you are looking for the official setup guide, please click here.
MetaMask is your entry point to the world of Ethereum - a blockchain platform designed for running apps and smart contracts.
This guide is focused on Android. Check out our iOS guide and our browser extension guide.
1. Introduction: What is MetaMask mobile app for Android?
The MetaMask mobile app consists of two main parts: a wallet and a web browser. The wallet supports any token compatible with Ethereum, and the web browser is preconfigured for interacting with dapps and smart-contracts.
MetaMask was first released in 2016, as a browser-extension, by ConsenSys - the first company focused on building decentralized tools and infrastructure. Both MetaMask and ConsenSys have played monumental roles in bringing Ethereum to the mainstream.
It is hard to overstate the effect MetaMask has had on the Ethereum ecosystem. By making dapps and smart-contracts simple and intuitive to use, activity on the Ethereum blockchain has enjoyed consistent growth.
Metamask is an open-source wallet, active development happens on github. The wallet has tons of features, and is constantly being updated and improved.
MetaMask is available as a browser-extension for Chrome, Firefox, Brave, and Edge. In September of 2020, MetaMask released a mobile app for iOS and Android.
2. How can you download and install MetaMask for Android?
- From your mobile device, open the 'Play Store' and search for 'MetaMask' or click this link: MetaMask - Apps on Google Play to download.
Trust, but verify. When using any cryptocurrency wallet, it is important to make sure you are downloading the correct version. Check the store listing for the following info:
Version: 1.0.10 as of January 26, 2021
Offered by: MetaMask
- The `Version` number and the `Updated on` date will change as the app is updated over time. The important part to verify is the `Offered by` field.
Remember the phrase trust, but verify. Taking the extra step to verify can prevent loss of funds. Trust, but verify is an important concept in having a security mindset.

3. How can you create and set up MetaMask for Android?
MetaMask is a very easy wallet to get started with. No email address or personal identification is required. The process consists of two main steps - creating a password and backing up your seed phrase. You will be ready to explore the world of Ethereum in just a few minutes.
MetaMask supports any token built on the Ethereum blockchain. You might come across terms such as ERC-20 and ERC-721; these are just types of tokens.
ERC-20 tokens are fungible; meaning they are like money - each token represents the same value.
ERC-721 are NFT's, non-fungible tokens - where each token represents a unique digital asset - like a collectible.
On the Ethereum Blockchain, there are a couple hundred thousand tokens in existence. MetaMask includes most of the popular tokens by default.
To add a token, simply tap `Add Token` and search for the token. If your token is not listed, select `Add Custom Token` and input the contract address - MetaMask will then pull the info automatically.
Safely backing up your MetaMask wallet is essential. This guide covers in detail how to securely back up your seed phrase in Section 5. Securely back up your seed phrase.
MetaMask uses BIP39 to generate a seed phrase for your wallet. Your seed phrase will cover every token, address, and transaction generated by your wallet. Think of it as your backup master key.
You can think of your seed phrase as a master backup of all your cryptocurrency in this wallet. It will unlock every single address created by your wallet. Backing up the seed phrase ensures access to your wallet using any BIP-39 compliant wallet. It is important to highlight, your seed phrase only ensures you will have access to your cryptocurrency inside your wallet. If someone steals your phrase, you will still be able to access the wallet, but the funds may be gone - since whoever knows your seed phrase can spend all of that cryptocurrency.
When creating a new MetaMask Wallet, the default method is to create your wallet within the app. The more advanced method is to generate your own seed phrase directly. We created detailed guides on how to create your own seed phrase.
By following the appropriate directions, you can generate a seed phrase that is more secure than the default method used by wallets.
If you already have a seed phrase, proceed to Section 6. Initialize or import seed phrase.
Create a New Wallet in MetaMask
In this section, you are going to create a new wallet in the MetaMask Android app using the wallet's default methods.To create a new wallet with a new seed phrase in MetaMask:
- Open the MetaMask extension and tap on `Get Started`. This will bring you to the `Wallet Setup` screen
- On the `Wallet Setup` screen you will be presented with 3 options:
- `Import using seed phrase`
- `Sync with MetaMask extension`
- `Create a new wallet` ← This is the one you want to select
- The first step is to create your password and set up your login settings
- MetaMask cannot reset your password for you. Check the checkbox to confirm you understand this concept. If you want to reset your password, you will need your seed phase
- Create your password using a combination of upper and lower case, numbers, and symbols. It's recommended to use a unique password that you have not used before.
- Sign in with Biometrics? MetaMask supports biometric authentication if enabled on your device. Decide if you want to use biometric authentication with your MetaMask account by switching the toggle on/off.
- When finished - tap on `Create password`
- MetaMask will now create your wallet and bring you to the next screen in the setup process
4. Verify your seed phrase
At this point, you will have a fully functioning cryptocurrency wallet that is able to store, send, and receive cryptocurrency. Before you put funds in your wallet, you need to create a backup and then verify your recovery phrase.
The process of backing up involves displaying your recovery phrase, backing it up, and then verifying that you have the correct phrase. To create a robust back up see Section 5. Securely back up your recovery phrase.
WARNING: When you follow the steps to find your seed phrase, you will be writing the seed phrase on a piece of paper. It is very important that you back up the seed phrase on a more reliable medium, and then destroy that piece of paper. Paper is vulnerable to accidental loss, theft, and damage. It is not the safest method of backing up your seed phrase.
- Secure Your Wallet - This is the most important step in creating your wallet. Here you will find your seed phrase, detailed instructions in Section 5 Securely backup your seed phrase.
- MetaMask will give you two options on the `Secure Your Wallet` screen.
- `Remind me later (Not recommended)`
- `Start (Highly recommend)`← This is the one you want to select
- MetaMask will display a warning before displaying your seed phrase:
- Writing your seed phrase on paper comes with risks!
- There are other options besides paper: Section 5. Securely back up your seed phrase of this guide is dedicated to teaching you how to safely backup your seed phrase.
- Tap on `Start` after you finish reading the warnings

- Tap `Complete Backup` when you are done
MetaMask reminds you on the last screen that it can't recover your wallet so that you have to back up your seed phrase in a safe way, It's your responsibility and an ultra-important task! Leaving a hint where you saved your backup is a good idea, but be careful of revealing the location of backup in a direct way, use something that no one can interpret, and of course, don't paste in your seed phrase.
Before you put funds in your wallet, you need to create a safe backup of your seed phrase. Your seed phrase is the only way to restore access to your funds if you lose access to your wallet.
You are now ready to proceed to Section 5. Securely back up your seed phrase and securely back up your funds.
Recommended Action: After you securely back up your seed phrase, it is important to destroy the paper you temporarily wrote your seed phase on.
5. Securely back up your seed phrase
If you used Vault12 to generate your seed phrase, then congratulations! Your seed phrase is already securely backed up in your digital vault.
Your seed phrase is the master key to all of your cryptocurrency funds. MetaMask Wallet uses BIP39, which is the current industry best practice for generating seed phrases. The majority of modern wallets today use BIP39. This means your MetaMask seed phrase can be used to access your funds across many different wallets without knowing your MetaMask password.
Securely backing up your seed phrase is the most important step in creating a new wallet. To emphasize how important this is, consider how someone with your seed phrase could access your funds without you knowing.
Imagine a bad actor has your seed phrase, and you have your Metamask Wallet locked down with 2FA, IP address whitelisting, blocked tor access, and all the other security features. The attacker could simply open any wallet application, and import your seed phrase. The attacker now has access to all of your funds.
We want you to have a secure backup, so this never happens to you.
Nine out of ten wallet providers only mention one way to backup your seed phrase - by writing the seed phrase on paper. Wallet providers only mention this paper backup method because it is easy for beginners to do. Paper backups are simply not that secure.
We did extensive research and compiled the best ways to backup your seed phrase. We cover all the most well-known options, including next-generation options like how to back up your seed phrase in Vault12.
Once you have safely backed up your seed phrase, you can initialize your wallet using any BIP39 compatible wallet. In the next section, you will learn how you can initialize a MetaMask wallet using your seed phrase.
6. Initialize or import seed phrase
If you are following this guide from the beginning, and created your MetaMask Wallet the default way, using the app to `Create a Wallet`, then congratulations! Just be cautious about storing high amounts of funds with a wallet-generated seed phrase.
You are now ready to start using your MetaMask wallet.
If you followed one of our guides for generating a more secure seed phrase, and you want to use that seed phrase in the MetaMask Wallet - this section is for you!
In this section, you will learn how to initialize your wallet using a pre-generated seed phrase. There are 3 main reasons to generate your wallet using this method:
- You lost access to your wallet, and you need to regain access to your wallet and your funds.
