# Other password managers

> Resolve a credential from another supported vault just in time.

An external-vault connection lets Darwin resolve an opaque item reference during authorized execution. The secret remains controlled by the external vault and is not imported into Darwin Vault.

## Resolve just in time

```text theme={null}
bounded connection interaction -> external item reference
                               -> authorized runtime resolution
                               -> transient use -> discard
```

Darwin stores connection metadata and the item reference needed for future resolution. Secret values are excluded from model context, Action results, logs, traces, analytics, and webhooks.

## Prefer a provider-specific adapter

Use the dedicated [1Password](/docs/act/connections/1password) or [Dashlane](/docs/act/connections/dashlane) guide when possible. Other password managers must provide a documented, scoped machine-access mechanism. A browser extension, copied export, screen scrape, or user master password is not an acceptable integration boundary.

The user can revoke the external-vault connection without deleting prior content-free Action receipts. Copying a secret into [Darwin Vault](/docs/act/darwin-vault) is a separate, explicit migration—not a side effect of resolution.
