Start with account access

Compromised credentials remain the primary entry point for AI-driven identity theft. Attackers use automated tools to test stolen logins across thousands of accounts, making your authentication methods the first line of defense. Before auditing specific data, you must lock down the doors.

Audit your password manager

Verify that your primary password manager is active and synchronized. Check for duplicate passwords, reused credentials, and weak entries. If you are not using a dedicated password manager, migrate to one immediately. A password manager generates unique, complex passwords for every service, eliminating the risk of a single breach compromising multiple accounts.

Enable multi-factor authentication (MFA)

Turn on MFA for every account that supports it, prioritizing email, banking, and social media. Prefer hardware keys (FIDO2/WebAuthn) or authenticator apps over SMS-based codes, as SIM swapping is a common vector for bypassing text-based verification. Review the list of connected devices and revoke access for any unfamiliar or old hardware.

Review third-party app permissions

Audit the third-party applications connected to your major accounts (Google, Apple, Microsoft, Facebook). Revoke access for apps you no longer use or do not recognize. Many of these apps retain permissions to read your data or post on your behalf, creating hidden vulnerabilities that AI agents can exploit to impersonate you or extract sensitive information.

Secure your recovery options

Ensure your account recovery emails and phone numbers are current and secure. If a hacker gains access to your recovery email, they can reset your password and bypass MFA. Consider using a dedicated, secure email address solely for account recovery purposes, isolated from your primary communication inbox.

Check for existing breaches

Visit Have I Been Pwned or similar reputable breach notification services to see if your email addresses or phone numbers have appeared in known data breaches. If you find compromised credentials, change those passwords immediately and ensure MFA is enabled on those specific accounts.

Lock down biometric data

Voice cloning and facial recognition spoofing are no longer theoretical threats. According to the International AI Safety Report 2026, general-purpose AI systems can now generate convincing biometric templates from minimal data, making your digital identity vulnerable to impersonation attacks. Unlike passwords, you cannot reset your face or your voice if they are compromised.

To mitigate this risk, you must audit where your biometric templates are stored and shared. Most apps and services do not store raw images or audio files; they store mathematical representations called templates. However, these templates can still be reverse-engineered or intercepted if the provider’s security is weak.

Start by reviewing your active biometric permissions on your device. Disable facial recognition and voice matching for any app that does not strictly require it for security purposes. For example, social media apps often use facial data for tagging, which is a convenience, not a necessity. Turn off these features in your system settings to reduce the surface area for attacks.

Next, audit your accounts for biometric login options. Many services offer face ID or voice print authentication as an alternative to passwords. While convenient, this creates a centralized point of failure. If a service provider suffers a breach, your biometric template may be exposed. Prefer traditional multi-factor authentication (MFA) using authenticator apps or hardware keys for high-value accounts like email and banking.

Finally, check your privacy settings on social platforms. Many platforms allow users to opt out of facial recognition tagging. This prevents your face from being used to train models or build profiles without your explicit consent. By limiting the collection and storage of your biometric data, you significantly reduce the risk of spoofing and identity theft.

Audit third-party integrations

Unused or legacy third-party applications are often the weakest link in your digital identity. AI agents can exploit these open permissions to harvest personal data without your immediate knowledge. A 2026 analysis by Cisco highlights that as AI adoption accelerates, the attack surface expands through these very integrations, making regular permission audits a critical defense layer.

To secure your accounts, you need to identify every application connected to your primary digital identities. Focus on social logins, email providers, and cloud storage services where you have granted "read" or "write" access.

1
Locate connected apps

Navigate to the security or privacy settings of your major accounts (Google, Apple, Microsoft, Facebook). Look for sections labeled "Third-party apps," "Connected accounts," or "OAuth permissions."

2
Review access levels

For each listed application, check the specific data permissions granted. Note whether the app has access to your email, contacts, calendar, or photo library. High-risk apps are those with broad data access that you no longer actively use.

3
Revoke unnecessary access

Remove permissions for any application you do not recognize or no longer use. Prioritize revoking access to apps that have not been used in the last 12 months. This action cuts off potential data pipelines for AI agents.

This process is not a one-time task. As you adopt new AI tools and services, new permissions will be granted. Schedule a quarterly review to ensure your digital perimeter remains tight. Regular audits prevent the accumulation of "permission debt" that security experts warn can lead to significant data breaches.

Verify identity proofs

When a high-stakes request arrives via voice or video, assume the medium is compromised until proven otherwise. AI-generated impersonations are now sophisticated enough to bypass casual observation. You must implement technical verification methods to distinguish between real human interactions and synthetic fraud.

Confirm with a secondary channel

Never rely solely on the communication channel where the request originated. If a CEO calls asking for an urgent wire transfer, hang up and call their verified office number. If a vendor emails a change of banking details, verify the new account via a phone call using a number found on their official invoice, not the email signature. This out-of-band verification breaks the AI’s ability to maintain real-time conversation.

Request specific biometric challenges

AI voice and video models often struggle with complex, spontaneous physical actions. During a video call, ask the individual to perform a specific, random action that requires physical presence. Ask them to hold up a handwritten note with today’s date and a unique phrase you provide. Request them to turn their head slowly or wave a specific object. Synthetic media often fails to maintain consistent lighting, background depth, or the physical coherence of these real-time interactions.

Use cryptographic identity tokens

For digital communications, rely on cryptographic proof rather than visual or auditory cues. Use platforms that support end-to-end encryption and identity verification, such as Signal’s safety numbers or enterprise SSO tokens. If sharing sensitive documents, use digital signatures that verify the sender’s private key. This ensures the message came from the claimed identity and hasn’t been altered in transit.

Verify with a pre-agreed code word

Establish a pre-agreed code word or phrase with key stakeholders for high-risk situations. Share this code through a secure, offline channel (like in person or via a secure internal messaging app) well in advance. If someone claims to be in an emergency and requests action, ask for the code word. AI systems cannot access these pre-shared secrets unless they have already compromised the secure channel, which is a separate and more difficult attack vector.
