Apparatus and passwords for providing double-sided estate password authentication via physical tokens and a distributed ledger

A system for providing double-sided estate authentication via a distributed ledger, the system comprising:

• a first physical electronic token, the first physical token configured to periodically generate a first random password in response to receipt of a periodic biometric signal from a first human;
• a second physical electronic token, the second physical token configured to periodically generate a second random password;
• and
• a distributed ledger, whereby each time the first random password is generated it is stored in the distributed ledger and each time the second random password is generated it is stored in the distributed ledger;
• wherein the first random password and the second random password comprise a dual-knowledge password for providing electronic access to an estate digital file;
• and
• wherein, following a cessation of the periodic biometric signal, the first token is configured to transmit the first random password to the second token for display thereon such that the second token is configured to receive and display the first random password substantially simultaneously to generating the second random password, and the distributed ledger is configured to store a date and time of the cessation of the periodic biometric signal.

A method for providing double-sided estate authentication via a distributed ledger, the method comprising:

• periodically generating, for display by a first physical token, a first random password, the periodically generating being in response to periodic receipt of a biometric signal from a first human;
• periodically generating, for display by a second physical token, a second random password;
• following each generation of the first random password, receiving and storing the first random password at a distributed ledger;
• following each generation of the second random password, receiving and storing the second random password at the distributed ledger;
• and
• following a cessation of the periodic receipt of the biometric signal, the first physical token is configured to stop generating the first random password, and the second physical token is configured to start generating the first random password in addition to generating the second random password;
• wherein the first random password and the second random password comprise a dual-knowledge password for providing electronic access to an estate digital file.
