Bulk Import MetaMask Wallets in Omnilogin

This tool automates importing multiple MetaMask wallets into browser profiles using seed phrases from an Excel file. It controls the official MetaMask extension directly, and all data stays local. For creating new wallets, see Create MetaMask Wallet.

How to Import MetaMask Wallets in Bulk

1. Install MetaMask extension from the Chrome Web Store in each target profile.
2. Prepare an .xlsx file with columns for wallet name, seed phrase, and notes.
3. Open the MetaMask import workflow in Omnilogin.
4. Enter the MetaMask Extension ID from your browser.
5. Provide the path to the .xlsx file.
6. Set a single Wallet Password (applied to all wallets in this session).
7. Click Run to start the import.

Security Notes

• Follow the principle: not your keys, not your coins -- keep your seed file encrypted and stored securely.
