Opportunities — the stories that would move this product's scores, from its own judged verdictsOpportunitiestop 8 of 40 stories with headroom

What would move 2FAS’s scores — derived from its own judged verdicts, biggest headroom first. Each line quotes what the judge found missing; shipping it (or evidencing it publicly) is the fix.

  1. Agenticness — how well agents can access and operate the productConnect an agent via an official MCP server

    nonemoves agent-readyimpact 45

    2FAS is a password/2FA manager, not an agent, so an MCP server axis could plausibly apply to its ecosystem; however evidence explicitly states 'Public API: None' and no OpenAPI/MCP endpoint exists, with probes confirming no API surface for agents to connect to.

  2. Agenticness — how well agents can access and operate the productDrive the product through a documented public API

    nonemoves agent-readyimpact 45

    2FAS explicitly states 'Public API: None' in its own llms.txt, and OpenAPI/swagger probes all return 404, confirming there is no documented public API to drive the product programmatically — it is local-first by design.

  3. Passkey support — passkeys in the vault — storage, sign-in, cross-ecosystem syncThe app stores passkeys and signs me into websites and apps with them, not just TOTP codes

    nonemoves PA Scoreimpact 30

    2FAS is a TOTP authenticator (2FAS Auth) and separately a password manager (2FAS Pass); evidence covers token/2FA codes, vault items, and password autofill, but nothing describes passkey (WebAuthn/FIDO2) storage or passkey-based sign-in to websites/apps.

  4. Agenticness — how well agents can access and operate the productSet up automations that run autonomously in the background

    nonemoves Built-in AIimpact 30

    The axis applies to this product kind (peer products hold positive or none verdicts on this story), so lack of evidence for an applicable capability is "none", never "na".

  5. Agenticness — how well agents can access and operate the productRun the product headlessly / in CI for automation

    nonemoves agent-readyimpact 30

    2FAS is a mobile authenticator/password manager with no CLI, headless mode, or API for CI/automation; the product's own llms.txt explicitly declares 'Public API: None' and is local-first by design, meaning it cannot be run headlessly or scripted in CI.

  6. Agenticness — how well agents can access and operate the productOperate the product with natural-language commands

    nonemoves Built-in AIimpact 30

    The axis applies to this product kind (peer products hold positive or none verdicts on this story), so lack of evidence for an applicable capability is "none", never "na".

  7. Agenticness — how well agents can access and operate the productUse an official CLI

    nonemoves agent-readyimpact 30

    2FAS is a mobile/browser 2FA and password-manager app with no evidence of an official CLI; docs explicitly note 'Public API: None' and no CLI tool is mentioned anywhere in the evidence pack.

  8. Agenticness — how well agents can access and operate the productIssue scoped/least-privilege API credentials for an agent

    nonemoves agent-readyimpact 30

    2FAS is a local-first authenticator/password manager with no public API; its own llms.txt explicitly states 'Public API: None' and no agent-callable endpoint for token generation, so there is no mechanism to issue scoped/least-privilege API credentials for an agent.
