🔐 Introducing TOTP Support in CroVault

April 20, 2025

Secure Your 2FA Secrets On-Chain

We’re excited to announce a powerful new upgrade to CroVault: support for TOTP (Time-Based One-Time Passwords)! You can now store your 2FA keys securely and privately—right inside your encrypted blockchain vault.

What is TOTP?

TOTP is the most widely used method for two-factor authentication (2FA). Services like Google Authenticator, Microsoft Authenticator, and Authy rely on TOTP keys to generate time-based 6-digit codes that verify your identity.

Now, with CroVault, you can store those sensitive keys directly on-chain, encrypted using your own password and wallet signature.

🧱 Why Store TOTP in CroVault?

✅ Bulletproof Backup

Lose your phone? As long as you remember your CroVault password and still own your wallet, you can recover your TOTP secrets instantly.

🔒 Privacy-First

Your data is encrypted before it ever touches the blockchain. Not even we can see your keys.

💡 All-in-One Vault

Store your credentials, notes, wallet addresses, and now—your 2FA keys. Everything in one decentralized, non-custodial vault.

🛠️ What You Can Do

Each TOTP entry includes:

• Name – Describe the account (e.g., “Binance”, “ProtonMail”).
• Key – The base32-encoded TOTP secret.
• Algorithm – Choose between SHA1, SHA256, or SHA512.
• Interval – The time window in seconds (usually 30).

The interface lets you:

• Add and batch-save new TOTP keys
• Edit or delete existing ones
• Expand entries to view or manage them
• Export raw decrypted TOTP keys when needed (e.g., to import into your authenticator app)
