## Content

## In Short
Cash-in has added a fingerprint app lock feature. The company says it adds an extra layer of protection for accounts that hold earnings and transaction history.

## What Happened
[Cash-in](/cash-in) says users can now lock the app with their fingerprint, which helps prevent unauthorised access.

The company says fingerprint authentication can be more convenient than entering credentials every time the lock is triggered.

To turn it on, users open the Cash-in app, go to the Profile section, tap “Enable Passkeys”, and follow the on-screen prompts to set up fingerprint authentication. After setup, users use their fingerprint when prompted to open up the app.

## Why It Matters
Cash-in frames the feature as added protection for “important financial information”, including earnings and transaction history. It also gives users more control over who can access the app.

For users who share devices or worry about someone opening the app without consent, an app-level fingerprint lock can reduce the risk of account access when a phone is opened up.

Cash-in’s setup path also highlights “Passkeys”, a login method that can use device biometrics like fingerprints to confirm identity.
