# Setup

### How can I set this up for my deposits?

Setting up Blink takes less than a minute, and happens right inside the app you want to deposit into.

Steps:

1. **Secure your Blink spending account with a passkey.** Save it to iCloud Keychain or Google Password Manager so you can access it across all your devices.

**2. Link to your existing wallet.** MetaMask, Phantom, Rabby, or wherever you hold your funds.

**3. Approve a spending limit.** This is the total amount your passkey can move across all apps where Blink is supported.

That's it. You're set up.

### After setup, how do deposits work?

Whenever you want to deposit, present your passkey, confirm the amount, and you’re done. You wont need to open your wallet and think through tokens, chains, and gas.

Once you confirm the amount and present your passkey, the funds move from your wallet and are routed into the app you want to deposit into.
