Two of the headline changes address pain points that have long made self-hosted Bitcoin payment infrastructure feel out of reach for non-technical merchants. Passkey authentication now lets users log in using Face ID, Touch ID, Windows Hello, Android biometrics, or a hardware security key, removing the need to manage passwords entirely. The guided multisig wallet setup is the other significant security upgrade: merchants can now create a multisig wallet directly inside BTCPay Server by starting a setup, choosing a signing policy, inviting co-signers, and broadcasting the transaction once all required keys have been collected. Previously, coordinating a multisig setup required managing everything externally, which put it out of reach for most small operators.
