Learn the best practices for keeping your assets safe of MetaMask
Setup a password manager
Be able to explain MetaMask to a friend
MetaMask is the most popular non-custodial wallet that holds your Ethereum based assets, be it a token, NFT art, or even your Ethereum identity. Non-custodial means that MetaMask doesn’t host or store your assets. Instead, MetaMask generates passwords and keys locally on your device, so only you have access to your accounts and data. You are 100% in control of what information you share with applications, and what to keep private.
With great power (of control and privacy) comes great responsibility. Here are some simple but essential security habits that will keep you surfing Web3 applications and using DeFi applications with confidence.
The Most Important Section
The two most important things to know are:
DON’T EVER SHARE YOUR SECRET SEED PHRASE.
BACK UP YOUR SECRET SEED PHRASE IN A COUPLE OF SECURE LOCATIONS, SUCH AS A PASSWORD MANAGER, COLD WALLET, OR WRITTEN AND SAFELY HIDDEN ON A PIECE OF PAPER.
KEEP YOUR SEED PHRASE SECRET, KEEP IT SAFE.
- Crypto Gandalf
Remember how we said that with MetaMask, you have unparalleled privacy and control over your assets? Only you will have access to your secret seed phrase. MetaMask is not able to reset your account or get your password. Never trust anyone that asks for your seed phrase to restore your account. This is a phishing attack.
DO NOT SKIP THESE STEPS.
💡 Phishing is a form of social engineering where a hacker impersonates a trustworthy entity to get sensitive information from a target such as data, usernames, passwords or any other sensitive details. An example might be someone on Telegram offering to help you if you send them your secret seed phrase.
Unlike traditional accounts you might have with a Web2 company, neither MetaMask nor anyone else are able to reset your account or retrieve a password.
The point of being decentralized is that you alone have complete control over these important keys. A simple explanation is, “not your keys, not your wallet.” If you do not ultimately control the keys to your financial castle, it’s not yours. We will explain more in depth why this is a powerful new concept for the web in a future post to keep this article focused and actionable.
💡If you could lose sleep because possible lost funds, then you should take this section seriously. Adopting these habits and setup will help keep your funds safe in the long run.
Set up your Password Manager
Before you install MetaMask, you should set up a password manager. Password managers are a unicorn in the security field, since they increase convenience and security. Usually, one comes at the expense of the other.
💡What is a password manager? It is a tool that securely stores your passwords by encrypting them and providing one master password to access all of them. Using one frees you up to only remember one password to access all your other passwords securely.
Why do you need a Password Manager?
They will make your life easier since you will only have to remember one password.
They generate passwords that are random, long, and hard to hack for better security.
They create new passwords so you won’t have to reuse old ones.
You can store your MetaMask seed phrase here initially to reduce the chance of losing your information.
Some popular password managers are 1Password and LastPass. There are others as well. Pick the one that has reviews from credible sources and works best for you. It is highly recommended you get the paid version. If you plan on having more crypto than the cost of a yearly subscription, then it is a good trade off for greater security.
Hackers can access your crypto by breaking into your email accounts, impersonating your phone number and/or leveraging your digital presence to trick others into revealing personal information. By completely hardening your passwords across all accounts, you can reduce these attacks.
If you are not convinced, see the video of this prominent cryptocurrency influencer on how he was hacked and almost lost all his crypto assets. You can search the internet for other cases of funds being stolen due to forgetting good security practices.
How To Create A Strong Password for your Password Manager: The Mind Map Method
Think of the layout of your childhood room or the location of a personal non-public place that doesn’t exist anymore.
List the items in the order you walk into the room or location.
Use this list as a password.
Add special characters and symbols in between each word to make brute force cracking harder.
The longer the password, the more secure.
An example can be:$LedZeppelinPoster.Chair.Be@[email protected]%
Reuse the master password used elsewhere for the password manager.
Save your password manager’s master password in phone’s notes, email or on your desktop.
Practice entering the master password often to memorize it.
Create a unique and memorable master password.
Make your master password type-able and easy enough to remember for you.
Backup your password manager account
Once you set up your password, download the emergency backup kit for your password. Print this piece of paper and save it in a SECURE location. If the location is fireproof, it is even better. This emergency backup kit will help reset your password manager’s master password in case you forget it.
Don’t be like this guy...Sorry Stefan. Hope you get access one day.
Or these guys. Avoid the problems. An ounce of prevention, beats doing the math to calculate how much you would have had.
Configure your password manager in this form to increase your security further.
Ninja Level Password Management
If you have 1Password, download and print your password manager’s emergency kit. Place this in a waterproof ziplock bag. Then place it in a safe place that is ideally fire and waterproof. See LastPass’s security tips for backups.
Set your password manager to auto-lock.
Automatically lock if idle or the screensaver comes on.
Automatically lock when logging off or exiting the application
Configure your password manager to lock the program after 1 minute. This configuration keeps you safe if you walk away from the computer briefly.
Remove Mac’s TouchID as an option to sign in and use the master password. You might have to access your information on a machine without Touch ID. Typing your master password often will help you remember it.
Clear the clipboard 20 - 30 seconds after copying. This option gives you enough time to paste your password, clears fast enough to avoid someone pasting and sending it to themselves.
🤔What if I have multiple password managers?Pick one and consolidate your passwords there. You can opt to have a secondary password manager in case of an emergency with the essential information.NOTE: The more avenues to access the password, the less secure the manager becomes. Choose wisely.
Did you set up your password manager? If not, go back and do so.
Now that you have set up your password manager, you will be able to securely save your seed phrase in an encrypted location. Let’s set up your MetaMask Wallet.
💡 Although some people may say that password managers are not decentralized enough, the article suggests pragmatic and easy to do instructions for people new to cryptocurrencies.

If someone wants to create a decentralized password manager, please have at it.

Your SECRET Seed Phrase
A secret seed phrase is a series of random words which act as your wallet’s password. The SECRET seed phrase opens access to your funds. This SECRET password is generated for your wallet and is FOR YOUR EYES ONLY.
💰🕵️ Treat your secret seed phrase with the same respect as your banking password. Would you share that? NO. Not even if a “customer service representative” asked for it.
⚠️ NEVER share your secret seed phrase with anyone. ESPECIALLY people claiming to be “MetaMask Support” and wanting to help with an issue. This is a common example of phishing and it occurs all the time.
