Install Noir Wallet, create or restore a wallet, and back up your recovery phrase.
Install Noir Wallet from the Chrome Web Store.
Confirm that the listing is Noir Wallet and that the extension ID is mfoghjbpfanobmnoemoepenjjcmfpmdn.
Open Chrome's extensions menu and pin Noir Wallet so it stays available in the toolbar.
Avoid unofficial downloads
Do not install wallet packages sent through direct messages or download an unpacked extension from an unknown source.
Set a strong local password. This password encrypts wallet data on this device.
Write the words down in order and keep the backup offline. Do not store it in chat, email, screenshots, or cloud notes.
Complete the recovery phrase check, then wait for the wallet to initialize and sync.
Choose Import Wallet, enter the recovery phrase in the original order, and create a local password for this installation. Restoring can take time because the wallet must scan Zcash history.
