New generation 2FA

Zelf Auth — Decentralized
2FA Protected by HumanAuthn

Why Zelf Auth

2FA should not
depend on fragile secrets

Most authenticator apps still force users into risky tradeoffs: either you keep your 2FA secrets only on one device and risk losing them forever, or you rely on centralized backup and syncing models that expand your attack surface.

Zelf Auth changes that model.

With HumanAuthn, your 2FA secrets can be biometrically encrypted and decrypted, then stored in a decentralized-first architecture designed to reduce dependence on third-party custodians.

How it works

A better way to
secure and recover 2FA

Explore Zelf Auth
Step 1

Create or import your 2FA accounts

Add your OTP-based 2FA accounts like you would in a standard authenticator app.

Step 2

Encrypt them with HumanAuthn

Your 2FA secrets are protected through biometric encryption/decryption, helping bind access to the legitimate user.

Step 3

Store them in a decentralized-first architecture

Encrypted 2FA data can be stored through IPFS, rather than depending only on centralized third-party storage patterns.

Step 4

Recover without the usual backup-key anxiety

Secure a Zelf ID and reduce the pain of lost phones, compromised backup flows, and insecure recovery habits.

Comparison

Compare Zelf Auth vs traditional authenticator apps

Most authenticator apps solve the code-generation problem. Zelf Auth is built to solve the recovery, storage, and resilience problem too.

Footnotes

Google and Microsoft can involve account-linked sync or ecosystem-linked recovery flows depending on setup. Google Authenticator can sync codes to a Google Account, and Microsoft Authenticator supports cloud backup/restore. 2FAS explicitly states it is open-source and anonymous.

Security / Backup / Pixnapping

Built for the threats other
authenticator apps ignore

Zelf Auth is not just about generating codes. It is about protecting the secrets behind them.

2FA secrets encrypted at rest
Human-rooted security

2FA secrets encrypted at rest

If recovery data exists, it should not exist in a fragile or casually exportable form. Zelf Auth keeps 2FA material encrypted at rest and tied to a human-rooted encryption model.

Never lose your backup keys
IPFS backup

Never lose your backup keys

Traditional 2FA setups often fail at the worst moment: lost phone, broken device, reset app, inaccessible backup, or compromised recovery path. Zelf Auth preserves your recovery keys as encrypted QR codes stored on IPFS, eliminating the tradeoff between convenience and permanent loss.

Positioning against Pixnapping
Pixnapping prevention

Positioning against Pixnapping

Researchers have shown that Pixnapping can leak sensitive information displayed on Android screens, including one-time codes from authenticator apps. Zelf Auth positions itself as a stronger model for users who want to reduce exposure around screen-visible secrets, backup leakage, and recovery compromise.

If your 2FA secret can be lost, unrecovered, or stolen via Pixnapping, it is not truly secure.

Upgrade from basic 2FA apps to decentralized 2FA security

Protect your 2FA with HumanAuthn biometric encryption, encrypted storage, offline access, and decentralized recovery architecture.
