Kaspersky Password Manager encrypts data using a symmetric key algorithm based on the Advanced Encryption Standard (AES). A key is derived from your master password using Password-Based Key Derivation Function 2 (PBKDF2).
The AES algorithm is used worldwide to protect top-secret data. This algorithm has low RAM requirements, which means your data is encrypted and decrypted within seconds.
The master password is a single password that Kaspersky Password Manager uses to protect all your data, including other passwords. You create the master password during the initial setup of Kaspersky Password Manager. Every time you try to access the data vault, Kaspersky Password Manager prompts you for the master password. If your device is running Android 6.0 or later, supports fingerprint authentication, and fingerprint authentication is enabled in the app settings, you can use it to unlock your vault instead of entering the master password.
It is recommended that you set a master password that is at least eight characters long and contains uppercase and lowercase letters, digits, and special characters.
For security reasons, Kaspersky Password Manager doesn't store the master password on any of your devices or in cloud storage. We recommend that you memorize your master password, or write it down and keep it in a secure place, because it can't be restored or recovered if forgotten.
If you forget your master password, you will no longer be able to access your data. In this case, you will have to create a new vault and protect it with a new master password. Then you will be able to add new data to the vault.
