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.
You can save a backup copy of your vault before deleting it. You can use it to restore your data if you remember your master password. When creating a backup copy of the vault, Kaspersky Password Manager exports entries to a file stored on your device. The backup copy is protected by the master password used when the backup copy was created. The backup copy is stored in encrypted form in the EDB format. By default, Kaspersky Password Manager creates backup copies in %Documents%\Kaspersky Password Manager\Backup.
