Digital authentication verifies the identity of a user or system component attempting to access a digital resource or perform an action. This process typically involves cryptographic proofs, such as private keys for signing transactions, or multi-factor verification methods. It confirms that the entity is who or what it claims to be, preventing unauthorized access and fraudulent activities. In blockchain, digital authentication secures wallet access and transaction authorization.
