Partial The vault UI and import flows are vibe-codeable, but a password manager needs correct encryption, secure key handling, and platform autofill and passkey integration, where mistakes are severe.
What it would actually take: The stack needs an audited cryptographic design (e.g., a vetted library with a sound key-derivation and encryption scheme), Android Autofill and iOS credential-provider extensions, and WebAuthn/passkey support. A real product needs independent security review and a threat model. The hard part is security correctness and platform integration, which go beyond vibe coding alone.
