You can't change the Apple or Google account email linked to your Phantom wallet. Instead, create a new wallet with a different email and transfer your assets.
- Create a new wallet using a different Apple or Google account.
- Send your assets from the old wallet to the new one. See Move assets when you need to start over with a new wallet.
- Sign back in to the old wallet and delete it: Settings → Security & Privacy → Delete Wallet.
Important: Emails used to buy crypto through providers like MoonPay, Coinbase, or Stripe aren't Phantom login emails. These providers use your email only for checkout and receipts. To change that email, contact the provider directly. See Contact information for on-ramp providers.
