The most important MetaMask screen is not the portfolio view. It is the confirmation window that asks a user to approve a transaction, signature or token permission. MetaMask is the browser-extension and mobile interface that manages those blockchain accounts and presents those requests. This tutorial was checked against MetaMask’s official extension and mobile guidance on September 3, 2026. Interface labels can change, so use the sequence and security checks as the durable guide rather than expecting every button to remain in the same position. Before installing MetaMask Decide what the wallet will be used for and which device will hold it. Update the operating system and browser first. Avoid a shared or remotely managed device for an account that will control valuable assets. Navigate from MetaMask’s official download page to the relevant browser store or mobile marketplace. Check the destination and publisher instead of installing from a search advertisement, direct message or copied download site. MetaMask is self-custodial in the sense that transactions require authority associated with the user’s account. Recovery and login options now differ, however, so read the setup screen carefully rather than following an old tutorial mechanically. Create a new wallet Open the installed application and choose Create a new wallet. Review the available setup methods. The extension may offer a traditional Secret Recovery Phrase route or supported social-login options. Create a strong, unique password. A device password protects local access; it is not automatically the recovery mechanism for every setup type. Follow the recovery instructions for the method selected and confirm that you understand what must be retained. Before receiving meaningful funds, close and reopen the wallet and verify that you understand how access would be restored on another device. With the traditional route, MetaMask generates a Secret Recovery Phrase, commonly abbreviated SRP. Anyone who obtains it can normally control every account derived from it. Record it accurately and keep it offline. Do not photograph it, paste it into cloud notes or send it to “support.” MetaMask says its staff will never ask for the phrase. MetaMask’s current wallet-creation documentation also describes supported social-login setup. That route still creates key material but changes how recovery works: access depends on the linked account and password, while encrypted components are handled differently. Do not assume advice written only for a manually stored SRP describes the social-login route. Import an existing wallet safely Importing a wallet does not move assets. It gives this MetaMask installation the authority needed to display and control accounts derived from an existing phrase or private key. Install MetaMask from the official source on a trusted device. Choose the option for an existing wallet. Select the appropriate recovery method. Enter an SRP only inside the genuine MetaMask application and only when restoration is necessary. After restoration, verify expected public addresses before initiating a transaction. An SRP can restore a group of derived accounts. Importing one private key normally imports only the corresponding account. MetaMask’s current import guide explains the distinction and the behaviour of supported login methods. Receive assets without exposing secrets A public account address is intended to be shared. A private key or SRP is not. Copy the receiving address from MetaMask, confirm the selected network and compare the complete address at the sending service. A token sent on an unsupported or unintended network may not appear where expected even if the address format looks familiar. For a first transfer, use a small test amount and confirm it on a reputable block explorer. Then repeat the address and network checks for the main transfer. The explanation of public keys, private keys, wallets and addresses shows why these objects are not interchangeable. Connect to a dApp and read the request A connect request usually reveals an address to the site; it does not by itself transfer tokens. The next prompt may be an offchain signature, token approval or blockchain transaction. Those actions have different consequences. Reach the application through a verified official domain. Select the intended MetaMask account and network. Read the action, destination contract, token, amount and fee. For approvals, inspect which contract becomes the spender and whether the amount is limited or unlimited. Reject an unexplained request. A failed connection is safer than an authorised malicious action. A polished website can construct a harmful request, and a legitimate protocol can be copied at a look-alike domain. Our dApp architecture guide explains why the frontend and smart contracts must be evaluated separately. Add networks and tokens carefully MetaMask can display accounts and assets across supported networks. When adding a custom network, obtain the chain identifier and RPC details from that network’s official documentation. A malicious RPC can misreport information or censor what the interface sees, although it cannot sign transactions without account authority. When a token is missing, verify its contract address from the project and a recognised explorer. Tickers and names are not unique. Adding a token changes what the wallet displays; it does not validate the asset. Backup and recovery checks Recovery should be planned before a device fails. Confirm which setup method controls the wallet, what credentials are necessary and whether separately imported accounts require their own private-key backup. Never test recovery by deleting the only working installation. If using an SRP, make at least one durable offline copy protected from theft, fire, water and accidental disposal. Do not type the phrase into a website that claims the wallet must be “validated” or “synchronised.” If the phrase has been exposed, create a new wallet through a clean official installation and move remaining assets after verifying every destination. For larger holdings, a hardware wallet can keep signing keys separate from the browser, but the user must still verify the transaction on the hardware display. See our hardware-wallet security practices. Maintenance checklist Keep MetaMask, the browser and operating system updated. Use a unique password and lock the wallet when it is not in use. Review connected sites and token approvals periodically. Separate everyday interactions from long-term storage where practical. Verify the network, contract and human-readable action before signing. Treat unsolicited support, urgent recovery prompts and requests for an SRP as hostile. A safer MetaMask routine is deliberately uneventful: install from the verified source, document the recovery method, test addresses, read every permission and reject unexplained urgency. Most irreversible mistakes enter through one of those five moments. Editorial note: this tutorial was fully reviewed and rewritten on September 3, 2026 using MetaMask’s official help material. It does not request or require a real recovery phrase or funded account.
