To strengthen defenses across the identity surface, we have added millions of breached phone credentials to our detection capabilities within Credential Guard
This enhancement allows organizations using Phone as an Identifier to proactively identify compromised credentials and trigger automated security responses, such as login blocks or password resets.
This expansion ensures that phone-based authentication is as secure as traditional email-based methods without impacting system performance.
