Coinbase Extension | Getting Started: Secure Device & Setup

Getting started with the Coinbase Extension is a simple way to access your self-custody wallet from a desktop browser. The extension lets you manage supported digital assets and connect your wallet with compatible decentralized applications. Because a self-custody wallet gives you direct control over your assets, setting up your device securely and protecting your recovery information should be your first priority.

Install the Coinbase Extension Safely

Begin by downloading the Coinbase Extension only from an official Coinbase source or a verified browser extension store. Avoid links shared through unsolicited emails, pop-ups, social media messages, or unknown websites. Fake wallet extensions can be designed to steal passwords or recovery phrases.

Before installing, check the publisher information and make sure the extension is the genuine Coinbase product. Once installed, open the extension and follow the on-screen setup instructions.

Create or Import a Wallet

When you open the extension for the first time, you can generally choose to create a new self-custody wallet or import an existing wallet.

If you create a new wallet, you will receive a recovery phrase. This phrase is one of the most important pieces of information associated with your wallet. Anyone who obtains it may be able to access the assets controlled by that wallet. Never share your recovery phrase with customer support, websites, friends, or anyone claiming to represent Coinbase.

If you already have a compatible self-custody wallet, you may be able to import it using its recovery information. Make sure you are entering the phrase only into the legitimate wallet application.

Secure Your Device Before Using Your Wallet

Your wallet security also depends on the security of your computer. Keep your operating system, browser, and security software updated. Use a strong device password or PIN, and avoid installing unnecessary or unfamiliar browser extensions.

When using the Coinbase Extension, be cautious with websites that request wallet connections. Check the website address carefully and avoid clicking suspicious links. A legitimate-looking website can still be designed to trick users into approving an unwanted transaction.

Protect Your Recovery Phrase

Your recovery phrase should be stored somewhere private and secure. Avoid posting it online or saving it in easily accessible locations such as social media messages, email drafts, or unprotected documents.

Do not take a screenshot of your recovery phrase if you can avoid it. Instead, consider keeping a secure offline copy in a location protected from unauthorized access, loss, or damage. Most importantly, never type your recovery phrase into a website simply because someone says it is required to verify or unlock your wallet.

Choose a Strong Password

During setup, create a strong and unique password for the extension. Do not reuse a password from your email, banking account, or another online service. A long, unique password can make unauthorized access more difficult.

Remember that your extension password and recovery phrase serve different purposes. Your password helps protect access to the wallet on your device, while the recovery phrase can be used to restore access to the wallet.

Connect to Decentralized Applications Carefully

After completing setup, you can use the Coinbase Extension to connect with supported decentralized applications. Before connecting, verify that you are visiting the correct website. When a transaction or permission request appears, read the details carefully before approving it.

Never approve a transaction simply because a website claims it is necessary to receive rewards, verify your wallet, or fix an account problem. If a request looks unfamiliar, stop and investigate it first.

Final Setup Checklist

A secure Coinbase Extension setup starts with a genuine installation, a protected device, a strong password, and careful handling of your recovery phrase. Take time to verify websites and transaction requests before approving them.

By following these basic precautions, you can use the Coinbase Extension more safely while maintaining control of your self-custody wallet and digital assets.
