Particle Connect gives you a unified login modal where users can choose between Web3 wallets or social logins. It includes a built-in viem provider with AA features, making smart account transactions possible without extra setup.
Particle Auth focuses on social logins only, provisioning an EOA wallet for the user and abstracting key management. Unlike Connect, it allows deep UI customization so you can tailor the login flow and embed it directly in your app. Pair it with the AA SDK to enable smart accounts.
