A 6-digit PIN is required to secure your wallet on your device. It’s also required to confirm each transaction you make on the blockchain, such as:
Registering an asset
Creating an agreement
Sending payments
Cash out
We recommended you use a unique PIN that does not include consecutive numeral inputs (e.g. 000000). If you forget your PIN, you can regain access to your wallet using your unique 12-word Passphrase.
See How to recover your wallet? for details.
