The master seed is a list of words that in combination represent the encrypted version of your private key or ‘secret key’. In a sense, the master seed is the key that unlocks your cryptographic secrets, and it is not just a common password or pin. It is a collection of randomly selected words generated by your device at the initial setup. If you lose access to your device, then you can unlock access to your assets on another device of the same type with this set of words.
