In general, a passkey is a unique cryptographic key to be used for authentication purposes. It's an added layer of authentication to secure your account in a way that is faster, easier, and more secure than traditional methods.
For Due Web App and Superlite, your passkeys serve as
your authentication to sign-in and link your account across different devices, and
your authorisation to sign and make transactions from your account.
For your passkey, you have the option to use:
your smartphone,
your Google or browser account (e.g. Chrome profile),
a USB key, or
another device you've authenticated previously, if any.
You can add and manage your passkeys anytime from your Settings, by heading to [Credentials] or [Security] → [Wallet keys].
Pro tip: we suggest setting up at least two passkeys, in case you lose access to one of them.
