Reading the label

What Authenticator App 2FA ◦ MFA's label means for you

Authenticator App 2FA ◦ MFA's label has 1 type under “Data Used to Track You”, 1 type under “Data Not Linked to You”. A data type can appear in more than one section when it is used for different purposes — for example, identifiers used for both analytics and advertising.

Tracking is the declaration that most separates apps. It means purchases from Authenticator App 2FA ◦ MFA can be combined with data from other companies to target or measure ads, or shared with data brokers. On iOS 14.5 and later, the app must ask your permission before tracking you through the advertising identifier; answering “Ask App Not to Track” blocks that identifier and tells the developer you have declined.

None of the data types fall into the categories most people consider sensitive: health, financial information, precise location, contacts, browsing history or the content you create.

Authenticator apps generate the second factor for your logins. The biggest practical risk is not data collection but losing your codes when you lose your phone. Turn on encrypted backup or export your accounts, and save the recovery codes each service gave you.

Among the 173 authenticator apps in our snapshot with a label, 36% declare tracking, 45% collect data linked to you and 40% say they collect nothing. Authenticator App 2FA ◦ MFA lists 1 data type, about the same as the average of 1.8 for this group.

Utilities range from calculators to VPNs, so their labels vary more than any other category. A simple tool that collects identifiers and usage data for tracking is a sign of advertising SDKs.

Read with care

What the label cannot tell you

  • A label is self-reported. Apple publishes the developer's answers and can reject apps that misrepresent them, but it does not independently verify what Authenticator App 2FA ◦ MFA sends.
  • It does not say where data is stored, how long it is kept, whether it is encrypted, or which companies receive it. The privacy policy covers those points.
  • Optional data counts: if a feature lets you add something (a profile photo, a phone number), the type is listed even if you never use the feature.
  • Data handled only on your iPhone is not 'collected', so a no-collection label is compatible with an app that reads your files locally.
  • Third-party sign-in, payment processors and SDKs are supposed to be included, but a label can lag behind a new version.
