Tested on Microsoft Surface Pro 2017 with KeePass 2.39.1 and 2.42.1.

How to Install

Place KeePassWinHelloPlugin.plgx into Plugins folder in your KeePass installation (by default is C:\Program Files (x86)\KeePass Password Safe 2).

Or you can use Chocolatey to install it in a more automated manner:

choco install keepass-plugin-winhello

Key storage

By default this plugin holds an encrypted master password in memory and removes it upon KeePass closing. In order to be able to unlock your database via Windows Hello authentication in between KeePass launches you may check "Store keys in the Windows Credential Manager" on in the Options dialog. This will prompts you for creating a persistent key signed with your biometry via Windows Hello. The key is used to encrypt master passwords for securely storing them in the Windows Credential Manager.

Options

The plugin integrates itself into the KeePass settings dialog.

Available settings:

Valid time period (default: 24 hours): Choose how long a saved key will be available. Once this period has expired you need to provide your full password to unlock the database again.
Storage location: Choose where to hold encrypted master passwords - in the KeePass process memory (by default) or in the Windows Credential Manager.
Revoke all: Allows you to delete all stored keys.

Notes

No sensitive information including master passwords for databases are stored by the plugin in a plain text. A database key is encrypted and decrypted using Windows Hello API in order to unlock the database.
