Sign in with wallet
You can use an external wallet with PZERO. Open sign in and choose Use a wallet instead. Connect that wallet and continue. You have now created an account in PZERO with your external wallet attached.
One Privy user still maps to one account. Email and wallet are different ways in, not different products.
Most users should start with an email on How to use Studio in 30 seconds. That path also gets an embedded wallet via Privy for settlement. This page is only for people who want to bring their own wallet.
Studio uses the session cookie. Inference still needs a Bearer pzero_… key. See Agents overview.
