Authentication & Portfolios

On first open (or after logout), you’ll see the Auth page with three tabs:

What You Can Do

Existing – Open an already created local portfolio.

New – Create a brand-new local portfolio.

Restore – Restore a portfolio into the offline environment.

Auto sign in — When enabled, the portfolio reopens automatically on this browser profile after restarts. You’ll still be asked for your password before any sensitive action.

Fields & Validation

Portfolio name

• Minimum 3 alphanumeric characters (A–Z, a–z, 0–9); no symbols
• Leading/trailing spaces trimmed; multiple inner spaces collapsed
• Examples: Main2025 ✅ · treasury01 ✅ · my wallet ❌ · dev#1 ❌

Password

• Minimum 4 characters
• For New and Restore, Confirm password must match

Restore file

• Type: JSON
• Obtain from:
  • Online Wallet → Settings → Backup portfolio, or
  • Offline Wallet → header → open dropdown → Backup icon

Naming & password advice

Use a short, descriptive portfolio name; avoid secrets in names.
Prefer a long passphrase (e.g., 4–6 random words) or 12+ mixed characters; avoid reuse.

After Auth

You’ll land on the Offline Tools page.

What you can do next:

1. Create or import a wallet → Add Wallet
2. Derive addresses → Wallet Expander
3. Protect your phrase as QR → QR Safe Keeper
4. Sign transactions offline → Sign Transaction

Security & Privacy

• All crypto operations run locally.
• Password input and decrypted content are rendered in the separate-origin signer iframe.
• If you lose the portfolio password, we cannot recover it.

Troubleshooting

Issue	Fix
Restore fails	Ensure the file is a valid portfolio JSON from Backup
Wrong portfolio opening	Log out and choose the correct one from Existing
