If you delete the MetaMask app, you lose immediate access to your wallet and must use your recovery phrase to restore it.
Loss of Access to Your Wallet
Immediate Inaccessibility
Deleting the MetaMask app from your device leads to the immediate loss of access to your wallet:
- Instant Disconnection: As soon as you uninstall the MetaMask app, you will no longer be able to view, manage, or transact with your cryptocurrency assets stored in that wallet through the app.
- Temporary Inconvenience: This disconnection is temporary and can be resolved, but it means you won’t have immediate access to your funds until the app is reinstalled and the wallet is restored.
Need for Recovery Phrase
To regain access to your MetaMask wallet after deleting the app, you will need your recovery phrase:
- Critical Importance: The 12-word recovery phrase is the most crucial piece of information for restoring your MetaMask wallet. Without it, you will not be able to recover your wallet and access your funds.
- Step-by-Step Restoration:
- Reinstallation: Reinstall the MetaMask app from the App Store or Google Play Store.
- Select “Import Wallet”: During the setup process, choose the option to import an existing wallet.
- Enter Recovery Phrase: Carefully enter the 12-word recovery phrase in the correct order.
- Create New Password: Set a new password for your restored wallet to secure it on the new installation.
- Security Precautions: Ensure that your recovery phrase is stored securely and only accessible by you. It should be kept offline in a safe place to prevent unauthorized access and potential loss.
Data and Settings Removal
App Data Deletion
When you delete the MetaMask app from your device, all associated data stored locally on that device is also removed:
- Wallet Information: The deletion process removes your wallet information from the device, including private keys, transaction history, and account balances stored within the app.
- Local Storage: Any data that MetaMask stores locally, such as cache files and temporary data, will be deleted. This ensures that no remnants of your wallet information remain on the device.
- No Cloud Backup: MetaMask does not store your private keys or wallet data on a central server, meaning all crucial data is lost if not backed up properly by the user.
Custom Settings Reset
Deleting the MetaMask app will also reset all custom settings you have configured within the app:
- Preferences Lost: Any custom preferences you set, such as network settings, gas fee preferences, and account labels, will be reset to their default state.
- Security Settings: Security settings, such as biometric authentication and password protection, will need to be reconfigured upon reinstallation.
- Connected DApps: Any DApps you connected to via MetaMask will lose their connection. You will need to reconnect and authorize these DApps again after reinstalling the app.
Recovery of Your Wallet
Using the Recovery Phrase
The recovery phrase, also known as the seed phrase, is essential for restoring your MetaMask wallet:
- Crucial Backup: The 12-word recovery phrase is your primary backup and the only way to restore your MetaMask wallet if the app is deleted or if you switch devices.
- Secure Storage: Ensure that your recovery phrase is stored securely, preferably offline, in a safe location. Avoid storing it digitally to prevent hacking risks.
Importing Wallet on a New Device

- Open the App: Launch MetaMask after installation.
- Select “Import Wallet”:
- Start Setup: On the welcome screen, tap “Get Started.”
- Choose Import Option: Select “Import using seed phrase” to begin the wallet restoration process.

- Access Your Wallet: Once the recovery phrase is validated, your MetaMask wallet will be restored with all your assets and settings.
Impact on Connected DApps
Reconnecting to DApps
When you delete and reinstall the MetaMask app, you will need to reconnect to any decentralized applications (DApps) you were previously using:
- Loss of Connection: Deleting the app removes all existing connections to DApps. This means you will have to manually reconnect each DApp you previously used with MetaMask.
- Restoration Steps:
- Open MetaMask: After reinstalling and restoring your wallet, open the MetaMask app.
- Access the DApp: Navigate to the DApp you wish to reconnect with using the MetaMask browser or your regular mobile/desktop browser.
- Connect Wallet: Look for the option to connect your wallet within the DApp and select MetaMask. Follow the prompts to establish the connection.
- Authorization Required: Reconnecting to a DApp will often require reauthorization. You will need to approve permissions for the DApp to interact with your MetaMask wallet, similar to the initial setup process.
Managing Permissions Again
Reinstalling MetaMask means you need to manage and reapprove permissions for DApps and other integrations:
- Review Permissions:
- Permission Requests: When reconnecting to each DApp, review the permissions being requested. Ensure that you are comfortable with the level of access the DApp requires.
- Limit Access: Where possible, limit permissions to the minimum necessary for the DApp to function. Avoid granting full account access unless absolutely necessary.
- Security Precautions:
- Stay Vigilant: Be cautious of phishing attempts or malicious DApps. Always verify that you are connecting to legitimate and trusted applications.
- Regular Checks: Periodically review the connected DApps and their permissions in the MetaMask settings. Revoke access to any DApps that are no longer needed or appear suspicious.
- Reapproval Process:
- DApp Interaction: Each time you interact with a DApp after reinstalling MetaMask, you will need to approve transactions and sign requests anew.
- Transaction Confirmation: Carefully review transaction details and gas fees before confirming any actions to avoid accidental transactions.
Security Considerations

Safeguarding your recovery phrase is paramount for the security of your MetaMask wallet:
