Set Passcode
Protects wallets
Passcode protects signing and operations that can alter security parameters. Passcode may be enabled or disabled during card configuration at the factory. Also, it’s possible to prohibit removing the passcode from the card once it’s set.
Passcode can consist of letters, digits or special symbols and can be any length.
Passcode can be set only if
card.settings.isSettingPasscodeAllowedistrue.Request
passcode <String> [optional]
Passcode to set. If empty, user will be prompted to enter code before operation.
cardId <String>
CID, Unique Tangem card ID number.
initialMessage <Message> [optional]
This message will be shown in the NFC session dialog.
Default: "Tap the card to your phone exactly as it shown above".
