Examples of the present disclosure describe systems and methods relating to master password reset in a zero-knowledge architecture. A master password reset may be used to regain access to encrypted user data despite not having access to the master password associated with decrypting the user data. As an example, the user data may be encrypted using a local ciphering key, wherein the key may be encrypted using a master password and stored. A second copy of the key may be stored, wherein the second copy may be encrypted using a recovery key. The recovery key may then be stored by a third party. In a reset scenario in which the master password is forgotten, the recovery key may be retrieved from the third party and used to decrypt the second copy of the local ciphering key, thereby providing access to the encrypted user data without use of the master password.
