Account & Wallet Onboarding

First-Time Registration (Passwordless)

• On your first launch, you can create an account without a password.
• The app generates a default, device-only account automatically so you can start using it immediately.
• No data is uploaded to any server during this step.

Using Your Own Account (Import a Wallet)

• If you prefer to use your own account, you can import an existing wallet at any time.
• Open the app and go to: Settings → Account → Import Wallet.
• Follow the on-screen steps to complete the import.
• After import, your wallet becomes your active account.

Notes

• Your keys are stored locally on your device. Make sure you back them up safely.
• You can keep using the default account or switch to your own wallet later—your choice.
• If you import a wallet, ensure you’re in a private, secure environment.
