Zero-Click Auth For Your Apps

Replit launched Repl Identity, a new authentication system that provides a PASETO token via the REPL_IDENTITY environment variable.

This token allows developers to verify users who run apps from a repl's cover page without requiring passwords or additional login steps, enabling features like high score tables and chat.

The system uses a chain of trust with public keys and supports custom verification in any language with a PASETO implementation.
