Read this before any login, signup, password change, or checkout so the right credential source is used in the right order without ever exposing a secret.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Credential manager
Use metadata to choose an account, then let the password manager detect and
fill the form. Never fetch, inspect, transform, or print a stored secret.
## Source order
Work down this ladder; stop at the first source that works.
1. **A configured external manager.** If the operator prompt explicitly names
1Password or Bitwarden, use its inline menu and read the matching provider
pack first (`../1password/SKILL.md`, `../bitwarden/SKILL.md`).
2. **BetterWright's built-in vault.** `credentials.list()` returns matching
metadata only: id, username, label, category, saved URL, and match mode.
Filter with `credentials.list({text, category})`. If one account clearly
fits the task, call `credentials.fill({id, submit: true})`. BetterWright
detects the visible form and resolves/types the secret internally. MCP/Pi's
`browser_login` and the SDK's `fillCredential` use the same path.
3. **The page itself.** Focus the username field with `human.click` and
re-snapshot; a session may already exist, an SSO button may be present, or
the user's own password manager may surface.
4. **Ask the user** through the host's question mechanism, offering the

How to install
mdr add betterwright/betterwright/credential-manager@sha256:f751c8b4e6f2b70dThe line at the top of this page pins the label git:20260719.dbff053, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
