Verdict

A basic encrypted vault is buildable, but browser autofill, mobile apps, and recovery make replacing a password manager casually a genuinely risky idea.

Core job

Store, generate, and autofill passwords across devices and browsers.

DIY replacement scope

A local encrypted vault with a CLI or simple UI; no autofill or mobile sync.

Requirements

  • a strong encryption library
  • secure key derivation
  • a backup plan

Technical dependencies

  • strong encryption library
  • key derivation
  • browser extension for autofill

What you lose

Moat

Why people still pay

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

Build prompt

Build me a local encrypted password vault, CLI-first (fictional example — development fixture, not researched). Requirements:

- A single-binary CLI using a well-audited encryption library and a proper
  key-derivation function; invent no cryptography of your own.
- One encrypted file holding entries: name, username, password, URL, notes.
- Commands: add, get <name> (copies to clipboard, clears after 20s), ls, gen
  (random password), edit, rm.
- vault backup writes a dated copy of the encrypted file to a configured folder.
- Out of scope: browser autofill, mobile apps, secure sharing, recovery.
- README: a short threat model and a clear warning that losing the master
  passphrase loses everything, with no recovery.

Recommended stack: Go or Rust CLI, a vetted encryption library
