Key Vault Credential Helper
Key Vault Credential Helper is a browser extension for Chrome, Edge and Firefox. On a site you have allowed, it signs you in to your own organization's Microsoft Entra ID and reads one secret from your organization's Azure Key Vault. It then hands that secret to the page that asked for it, so the page can fill in a password for you.
The extension talks only to Microsoft: login.microsoftonline.com to sign you
in and *.vault.azure.net to read the secret. It sends nothing to us.
