Last May, Google introduced the relatively minor “Click to reveal PIN” feature, which hides all two-factor authentication codes from view, allowing users to reveal only the codes they want to use.
It seemed like a fairly innocuous inclusion, considering that 2FA codes change every 30 seconds anyway. But Google apparently doesn’t see it that way, as the feature has disappeared from the Authenticator app following an update last week.
This removal is part of the Google Authenticator version 5.20R4 update (available via APK Mirror), which doesn’t contain any other notable additions, 9to5Google reports. As per the release notes on the app’s Play Store listing, it includes device encryption for the “storage of secret values.”
