Summary: MetaMask, a decentralized wallet, doesn't offer a traditional "Log Out" feature but provides an equivalent "Lock" function that requires re-entry of your password for access and transactions. Locking your account, especially when not in use, is crucial for mitigating risks like unauthorized access, phishing attacks, and malware.
It's your responsibility to maintain your wallet's security, ensuring your password and secret recovery phrase are kept secure and private.
Can you Log Out of your MetaMask Wallet?
Unlike traditional applications, MetaMask doesn't have a typical "Log Out" or "Sign Out" option. Instead, what you do is "Lock" your account. Locking your account in MetaMask makes it so that you need to re-enter your password to see your account and conduct transactions. This is essentially the equivalent of logging out.
How to Log out of MetaMask
Here is how you can lock your account in MetaMask:
- Click on the MetaMask icon in your browser to open the extension.
- On the top right corner, you will see an icon that looks like a circle with an identicon (the colorful geometric representation of your address) or your account image if you set one.
- Click on that icon.
- A drop-down menu will appear. In the menu, there should be an option that says "Lock". Click on that.
Your account is now locked and anyone trying to access it will need to input the password again. Remember, you should always keep your password and secret recovery phrase secure and private to protect your wallet.

What is the Risk of Staying Logged In?
Staying logged into your MetaMask wallet can pose a number of security risks, especially if your device is shared, lost, or compromised. Here are a few potential risks:
- Unauthorized access: If your device falls into the wrong hands while you're still logged into MetaMask, someone could access your wallet and make transactions without your consent.
- Phishing attacks: If you accidentally visit a malicious website while your MetaMask wallet is unlocked, the website might attempt to interact with your wallet in a malicious way, such as trying to initiate unwanted transactions.
- Malware: If your computer is infected with malware, an attacker could potentially access your unlocked wallet.
Given these risks, remember to lock your MetaMask wallet when not in use. Keep your computer secure, don't share your password or recovery phrase, and be careful when browsing online. As a decentralized wallet, MetaMask gives you full control but also makes you responsible for your security.
Final Thoughts
In conclusion, the importance of your security when using MetaMask cannot be overstated. While it may not provide a traditional 'log out' option, locking your account serves a similar purpose, effectively securing your wallet by requiring password re-entry for further use. This feature should be employed regularly, especially when your device is not in use, to mitigate potential risks like unauthorized access, phishing attacks, and malware.
