Passary Extension

Secure autofill and save prompts for an unlocked, paired Passary vault.

Passary Extension fills credentials from a Passary vault that is open and unlocked in the same Chrome profile. It does not require a Passary account or a cloud-hosted vault. Use the popup to choose the exact form and vault item you want to fill. Passary supports login and one-time-code fields, split sign-in steps, multiple forms, supported HTTP(S) frames, open shadow roots, payment cards, identities, addresses, and explicitly configured autofill custom fields. The extension can also: - save a generated password before a sign-up form is submitted - offer save or update actions after a supported login submission - add an exact new site to an existing login when the submitted username and password match - exclude a hostname from autofill and credential capture - explain which fields were filled, skipped, blocked, or unavailable Passary never submits forms automatically. HTTP fills require an explicit warning confirmation, and a credential saved for HTTPS cannot be downgraded to HTTP. Each Chrome installation is paired with a vault using a separate 256-bit key. Credential requests are authenticated, expire quickly, reject replay, and receive encrypted responses. Locking the vault or revoking the pairing removes credential access. The extension stores no master password, decrypted vault copy, analytics, telemetry, or advertising identifier. Current requirement: the matching Passary vault tab must remain open and unlocked while using the extension. Closed shadow roots, opaque frames, and browser-restricted pages require manual copy from the vault.
