Privy

Privy is a simple toolkit for progressive authentication in web3. Privy builds authentication, authorization and data control tooling so developers can deliver amazing products that keep users safe.

Privy allows you to meet your users where they are. What does that mean?

• Onboard users across traditional and web3 authentication methods. Users can sign in to your app with a crypto wallet, an email address, their phone number, or even a social profile (e.g., Twitter or Discord). Users don't need to have a wallet to explore your product.
• Enable progressive onboarding to boost user conversion. Require a wallet from your user only once it’s needed. With fine-grained control over when to trigger authentication flows and wallet connections, you can improve conversion and craft better UX.
• All auth methods create a common user object for your app. A user is a user, regardless of whether they've connected with a wallet, email or Discord account. No endless branching in your code logic to support more users. Allow users to link as many identifiers as they'd like to one underlying account.
