View and change ESPL’s security settings.

  1. Tap “Security”.

  1. The settings page opens. (1) Change PIN

    Change the 6-digit PIN used for transaction confirmation and similar moments.

    (2) Require PIN at launch

    Choose whether to require the 6-digit PIN when the app launches.

    (3) Use Face ID (or Touch ID)

    Choose whether to use Face ID when logging in. When enabled, a quick glance is enough to unlock iPhone / iPad, authorize purchases, and sign in to apps.

    (4) Enable two-factor authentication

    Two-factor authentication adds a second verification step that strengthens security. Even if your password leaks, no one else can access your account. Enable two-factor authentication.

    (5) Show private key

    • Use this when exporting wallet information to MetaMask and similar.

    • The private key is the wallet’s cryptographically secure 256-bit random number, expressed as 64 hex characters. After entering your PIN, you can display the wallet’s private key. The private key is used to sign every blockchain transaction — sending crypto-assets or tokens, sending challenges, sending step data, and so on.

    • Do not save the private key on a PC or in cloud storage, and do not share it with anyone.

    • One effective approach is to paste the private key into a note, print it, save the data to a USB stick, and keep both the printout and the USB stick in a secure place.
