What an LLM can build

The achievable core

  • Create a local encrypted vault, generate passwords, search entries, and optionally sync the encrypted database with a cloud drive.
  • Prototype the workflow, but rely on audited libraries and established security tools.
  • A responsive interface with real empty, loading, success, and error states.
Where the clone breaks

The parts a prompt cannot buy

  • browser/mobile autofill
  • passkey support
  • secure sharing
  • recovery
  • Trust, audits, and counterparties matter more than feature parity.
  • The last 20 percent is sync, migration fidelity, speed, and edge cases.
Defensibility

Why people still pay

They pay because password managers are one place where reliability and audited security beat saving a few dollars.

Context

**1Password** — Password manager for logins, passkeys, secrets, and secure sharing. It currently costs $2.99/mo.

A basic encrypted vault is buildable, but browser autofill, mobile apps, passkeys, sharing, recovery, audits, and trust make this a dangerous thing to replace casually.

This brief describes a focused, single-operator replacement for the part of 1Password that is genuinely reproducible. It is deliberately narrower than the product it replaces, and it says so in writing. Build the useful core; do not pretend to have rebuilt the rest.

What you are building

Create a local encrypted vault, generate passwords, search entries, and optionally sync the encrypted database with a cloud drive.

Prototype the workflow, but rely on audited libraries and established security tools.

A responsive interface with real empty, loading, success, and error states.

Requirements

Functional

Strong encryption library.

Browser extension if autofill matters.

Mobile/desktop storage.

Backup plan.

Data and integrations

Secure key derivation.

Each of these needs a real account, credential, or quota. Set them up before writing feature code.

Non-functional

Accessibility: semantic markup, labelled controls, visible focus, and reduced-motion support.

Security: server-side secrets, validated input, and no credentials in the client bundle.

Reliability: retries with backoff on external calls, and a clear failure state when a provider is down.

Portability: the operator can export their data and leave without losing it.

Implementation brief

Build me a local encrypted password vault to replace 1Password, CLI-first. Requirements:

A single-binary CLI in Go using filippo.io/age for encryption and Argon2id

(golang.org/x/crypto) to derive the key from my master passphrase. Use the

library primitives exactly as documented, invent no crypto.

The vault is one encrypted file at ~/.vault/vault.age holding JSON entries:

name, username, password, URL, notes, updated timestamp.

Commands: add, get <name> (copies to clipboard, clears it after 20 seconds),

ls, gen (32-char random password), edit, rm.

Fuzzy name matching on get; never print a password to stdout unless --show

is passed.

vault backup writes a date-suffixed copy of the encrypted file to a folder

set in .env; it is already encrypted, so any cloud drive can sync it.

Import from a 1Password CSV export so I can migrate in one command.

Everything local: no server, no accounts, no telemetry.

Out of scope: browser autofill, passkeys, and secure sharing. Those are why

people pay 1Password; if I need them the honest move is KeePassXC or

Bitwarden, say exactly that in the README.

README: a five-line threat model, how key derivation works, and a warning

that losing the master passphrase loses everything, there is no recovery.

Delivery standard

Inspect the repository first, then write a short implementation plan before writing code.

Deliver the smallest complete end-to-end workflow first; every primary control must work against persisted data.

Use real validation and storage; never substitute fake dashboards, decorative controls, hard-coded success states, or mock integrations.

Include responsive layouts plus genuine empty, loading, success, validation, and failure states.

Keep secrets server-side in environment variables, provide .env.example, and never commit credentials or user data.

Add structured logs around every external call and return actionable errors without leaking sensitive details.

Write unit tests for the core logic and one automated test of the main user journey.

Finish with a README covering setup, architecture, data location, backups, tests, deployment, and known limitations.

Acceptance criteria

A clean install starts the app using only the README and .env.example.

The primary journey works from first visit through saved result, reload, edit, export, and deletion where applicable.

Invalid input, missing configuration, provider failure, and an empty database each have a usable state.

The interface works at 390px and 1440px, is keyboard navigable, and shows visible focus on every control.

Tests, type checking, linting, and a production build all pass with no ignored failures.

No part of the interface implies a live integration, security guarantee, or scale capability that was not actually built and verified.

Non-goals

Do not build these, and do not claim to have replaced them:

Browser/mobile autofill.

Passkey support.

Secure sharing.

Recovery.

Trust, audits, and counterparties matter more than feature parity.

The last 20 percent is sync, migration fidelity, speed, and edge cases.

What you still own after launch

Secure credentials, rotate secrets, and handle provider rate limits.

Run migrations, backups, restores, and dependency updates.

Test the critical journey after every model, API, or hosting change.

Monitor failures and fix the edge cases a first prompt will miss.

Risk

**High consequence.** Use this as a prototype or personal aid. Keep a qualified human and an established provider in the loop for consequential decisions.

Editorial confidence in this assessment: high. No independent one-shot implementation is linked yet.

Practical questions

Before you start

Can 1Password be vibe coded?

Partly, if you narrow it. A basic encrypted vault is buildable, but browser autofill, mobile apps, passkeys, sharing, recovery, audits, and trust make this a dangerous thing to replace casually.

What can an AI coding agent reproduce from 1Password?

Create a local encrypted vault, generate passwords, search entries, and optionally sync the encrypted database with a cloud drive. Prototype the workflow, but rely on audited libraries and established security tools. A responsive interface with real empty, loading, success, and error states.

What will a DIY 1Password replacement still be missing?

browser/mobile autofill; passkey support; secure sharing; recovery; Trust, audits, and counterparties matter more than feature parity.; The last 20 percent is sync, migration fidelity, speed, and edge cases.

What do I still own after building a 1Password alternative?

Secure credentials, rotate secrets, and handle provider rate limits. Run migrations, backups, restores, and dependency updates. Test the critical journey after every model, API, or hosting change. Monitor failures and fix the edge cases a first prompt will miss.
