This article explores how passkeys—a secure, user-friendly authentication method already adopted in Web2—are being integrated into Stellar's blockchain to improve user experience and drive adoption. Stellar gained a significant advantage by implementing native secp256r1 support in Protocol 21, enabling passkey functionality directly at the protocol level rather than through third-party solutions.
The article addresses blockchain's adoption challenge, noting that despite its potential, only ~300 million people use blockchain compared to 5+ billion Web2 users. A primary barrier is poor user experience, particularly around managing private keys and passphrases in non-custodial wallets. Passkeys—cryptographic keypairs secured on user devices and accessed via biometrics—offer a solution already proven in Web2 services like Amazon and PayPal. Stellar has a unique advantage: its recent smart contract platform (Soroban, launched February 2024) allowed passkey support to be built directly into the protocol via Protocol 21 (June 2024), which added native secp256r1 verification. This native implementation is faster, more efficient, and inherently compatible with the ecosystem compared to layer 2 solutions. The article details how passkeys work in practice and highlights emerging Stellar projects like Passkey Kit, Launchtube, and KALE that leverage this capability.
