  • Free Plan
    Yes — 50 accounts, 1,000 API calls/month
  • Simple CLI tool
    2fa is a lightweight command-line two-factor authentication tool that generates TOTP codes directly from the terminal, making it convenient for developers and power users who prefer working in the command line.
  • No phone dependency
    By storing 2FA secrets on your computer, you eliminate the need to pull out your phone every time you need a TOTP code. This is especially useful when working at a desktop and logging into services frequently.
  • Easy integration with workflows
    As a CLI tool, 2fa can be easily scripted and integrated into automated workflows, shell scripts, or combined with other command-line tools for streamlined authentication processes.
  • Minimal and focused
    Written in Go by Russ Cox (a prominent Go team member), the tool is minimal, well-written, and does one thing well — generating time-based one-time passwords. It has very few dependencies and is easy to build and install.
  • Open source and auditable
    The source code is publicly available on GitHub, allowing users to inspect, audit, and verify the security of the tool themselves, which is important for a security-sensitive application.

Possible disadvantages

  • Secrets stored on local machine
    Storing 2FA secrets on your computer means that if your machine is compromised, an attacker could gain access to both your passwords and your 2FA codes, effectively defeating the purpose of two-factor authentication.
  • No encryption by default
    The secrets are stored in a plain text file (in the user's home directory), which means anyone with access to the filesystem can read the 2FA keys without needing to decrypt anything, posing a significant security risk.
  • Limited maintenance and updates
    The repository has minimal recent activity, and as a small personal project, it may not receive timely security updates or new features compared to more actively maintained alternatives.
  • No backup or sync features
    The tool does not provide built-in backup, sync, or export functionality. If you lose your machine or the stored secrets file, you lose access to all your 2FA codes and must reset them with each service individually.
  • Reduces security of 2FA
    Two-factor authentication is designed to require something you know (password) and something you have (a separate device). By putting 2FA on the same computer where you enter passwords, you collapse both factors into a single device, weakening the security model.

Overall verdict

  • I don't have verified information about BlobsVault (blobsvault.com) as it doesn't appear to be a well-known or widely-documented service, so I can't confirm its legitimacy, quality, or safety.

Why this product is good

  • No reliable public information, reviews, or track record found for this site
  • Unable to verify company registration, ownership, or business legitimacy
  • Cannot confirm security practices, data handling, or customer service quality
  • No verifiable user testimonials or independent reviews located

Recommended for

  • Not recommended without independent verification
  • Only for users willing to conduct their own thorough due diligence first
  • Consider checking domain age, WHOIS data, SSL certificates, and third-party review sites like Trustpilot before engaging
  • Avoid entering payment or personal information until legitimacy is confirmed through independent research

Overall verdict

  • GitHub's two-factor authentication (2FA) is a highly recommended security feature that significantly strengthens account protection against unauthorized access, and it's now mandatory for many contributors.

Why this product is good

  • Adds a critical second layer of security beyond just a password, protecting against credential theft and phishing.
  • Supports multiple methods including authenticator apps (TOTP), security keys (WebAuthn/FIDO2), and passkeys for flexibility.
  • Free to enable for all GitHub users at no additional cost.
  • Helps safeguard source code, sensitive repositories, and supply chain integrity.
  • Provides recovery codes so you can regain access if you lose your primary device.

Recommended for

  • Developers and maintainers who host code and projects on GitHub
  • Organizations and teams needing to protect proprietary or sensitive repositories
  • Open source contributors who want to secure their accounts and the software supply chain
  • Anyone concerned about account takeover, phishing, or credential-based attacks

Questions & Answers

As answered by people managing BlobsVault and 2fa.

Why should a person choose your product over its competitors?

BlobsVault's answer

No other 2FA manager offers an MCP server, per-agent scoped keys, or a REST API designed for programmatic access. Google Authenticator, Authy, and 2FAS are all built for humans — none of them can be connected to an AI agent, CI/CD pipeline, or automation script without dangerous workarounds.

BlobsVault is also architecturally zero-knowledge. Unlike most competitors, we cannot decrypt your vault even if we wanted to — the master password never leaves your device.

For teams, per-member encryption means no central point of compromise. For developers, the open-source MCP server and SDKs mean you can audit the implementation before connecting your agents.

How would you describe the primary audience of your product?

BlobsVault's answer

BlobsVault serves three main audiences:

  1. AI builders — developers building agents with Claude, Cursor, or any MCP-compatible tool that need 2FA access without manual intervention or hardcoded secrets.

  2. DevOps and platform engineers — teams running CI/CD pipelines, automation scripts, and infrastructure tools that need programmatic TOTP generation via REST API or CLI.

  3. Security-conscious individuals and small teams — people who want a 2FA manager where the provider genuinely cannot read their secrets, with team sharing and audit logs.

Which are the primary technologies used for building your product?

BlobsVault's answer

Frontend: React, Vite, Tailwind CSS Backend: Node.js, Express Database: PostgreSQL Infrastructure: Docker, Nginx, Let's Encrypt SSL, Contabo VPS Payments: Paddle Email: Zoho SMTP Authentication: Passport.js (Google and GitHub OAuth) MCP Server: open source, MCP protocol SDKs: Python, Node.js — open source on GitHub CLI: blobsvault-cli on npm Encryption: AES-256 client-side, PBKDF2 key derivation

Who are some of the biggest customers of your product?

BlobsVault's answer

BlobsVault is an early-stage product launched in 2026. We are not disclosing specific customers at this time. Our current users include individual developers and AI builders using the MCP server and REST API to give their agents secure 2FA access.

What makes your product unique?

BlobsVault's answer

BlobsVault is the only 2FA manager built specifically for AI agents and programmatic access.

Every other authenticator app is designed for humans tapping phones. BlobsVault is designed for code.

Three things make it unique: a native MCP server (Claude, Cursor, and any MCP-compatible agent generates 2FA codes natively), per-agent scoped identities (each agent gets its own bvagent* key restricted to specific accounts, tracked, and revokable independently), and zero-knowledge encryption (AES-256 client-side — the server only ever stores ciphertext). The MCP server, SDKs, and decoder are open source on GitHub.

What's the story behind your product?

BlobsVault's answer

BlobsVault started from a problem I kept hitting while building AI agents: services protected by 2FA would stop the agent cold. Every authenticator app is designed for humans — there was nothing built for code.

I wanted a solution where each agent gets its own identity, with scoped access, audit trails, and instant revocation. And because 2FA secrets are extremely sensitive, I also wanted zero-knowledge encryption — where the architecture makes it impossible for the provider to read your secrets, not just a promise in a privacy policy.

I built BlobsVault solo from Madagascar. It's my first SaaS product, and the MCP + agent identity model is what I wish had existed when I started building agents.
