What is a 2FA Audit and Why Does ARK Include One?
A 2FA audit is a security check that verifies which of your online accounts have two-factor authentication enabled. ARK: Mobile Security Score includes a 2FA audit as part of its Shield tier, letting you see at a glance which accounts need stronger login protection.
What 2FA Audit Does
Two-factor authentication, or 2FA, requires two separate methods to log into an account: something you know (like a password) and something you have (like a phone code or security key). A 2FA audit examines your device and cross-references your online accounts to identify which ones are protected by 2FA and which ones rely on password alone. ARK's 2FA audit, available in the Shield tier (£2.99/month or £29.99/year), scans your phone's stored credentials and authentication apps to report coverage gaps. This helps you prioritise which accounts need stronger protection first.
Why 2FA Matters for Your Security
Passwords alone are no longer sufficient defence against account takeover. Attackers can buy stolen credentials on the dark web or use phishing to steal them. With 2FA enabled, even a compromised password cannot unlock your account without the second factor, which only you possess. Banking, email, and social media accounts are the highest-priority targets for 2FA protection. ARK's audit identifies these gaps so you can add 2FA to the accounts that matter most before a breach occurs.
How ARK's 2FA Audit Works
ARK scans your device to detect installed authentication apps (like Google Authenticator or Microsoft Authenticator) and checks which of your stored passwords are associated with 2FA-enabled services. The audit generates a report showing your 2FA coverage percentage and highlights which major services still need protection. Results include one-tap remediation links that direct you straight to account security settings on each platform. Privacy-first processing means the audit runs on your device; ARK does not store account names or contact details from the scan.
2FA Audit as Part of Broader Mobile Security
A 2FA audit is one scan within ARK's comprehensive mobile security toolkit. Your device also gets a 0-100 security credit score that reflects permission risks, breach exposure, network leaks, and account protection. The Shield tier adds dark-web monitoring, phishing scanner, Wi-Fi analyser, password health check, and DNS leak testing. The Fortress tier goes further with data-broker exposure checks and GDPR automated data-subject requests. Together, these scans give you a complete picture of your mobile security posture.
Who Should Run a 2FA Audit
Anyone who has experienced a data breach, uses public Wi-Fi regularly, or manages sensitive work data on their phone should audit their 2FA coverage. Parents checking family devices and small business owners managing employee phones also benefit from seeing which accounts are properly locked down. As of 2026, 2FA remains one of the strongest defences against account compromise. ARK makes the audit accessible and actionable, not just a report you file away.

Frequently asked questions
Is 2FA audit the same as a password manager?
No. A 2FA audit checks which accounts have two-factor enabled; a password manager stores and encrypts your passwords. ARK audits 2FA but does not store passwords. You need a separate password manager app for that.
Does ARK's 2FA audit work if I don't have authentication apps installed?
ARK will still scan for accounts that use 2FA methods like SMS codes or email verification links, but detection is most accurate if you use an authenticator app. Installing Google Authenticator or Authy gives ARK more visibility into your 2FA setup.
Can I see which specific accounts need 2FA?
Yes. ARK's 2FA audit report lists major services (email, banking, social media) and shows which ones are already protected. One-tap links in the report take you directly to each service's security settings to enable 2FA.
Is my account data safe during a 2FA audit?
Yes. ARK runs the audit on your device using privacy-first processing. Account names and email addresses are stored in iOS SecureStore, not plain text, and are not sent to ARK's servers on the free tier or during Shield scans.
Which ARK tier includes 2FA audit?
2FA audit is part of the Shield tier (£2.99/month or £29.99/year). The free tier includes a basic security score and stalkerware detector; Fortress tier adds even more scans like data-broker exposure and GDPR compliance checks.
How often should I run a 2FA audit?
Run it once to identify gaps, then re-run it every 3-6 months or whenever you sign up for new services. ARK lets you schedule recurring scans so you don't have to remember.
