At the end of May, Google Authenticator got it first update In a year that hides your 2FA codes until you click to reveal them. An update to Authenticator this week sees Google pull back on the feature.
Google Authenticator version 5.20R4 removes the “Click to reveal PIN” feature so that you can immediately see both two-factor authentication codes in that list after opening the app.
Click to reveal is likely Google’s attempt to add another layer of security by making it a little harder for those in your physical proximity to peek at your phone’s screen and grab something. Still, the codes already change every 30 seconds, so it’s unclear how effective this measure is. An unexpected aspect of this feature was that it helps you focus by displaying only the code you want.
This update never made it to the iOS app, and it might prompt you to authenticate Face/Touch ID It would be a nice option to have on Android before rendering codes and for shared device use cases.
Meanwhile, Google has updated Authenticator Play Store release notes saying that it “adds device encryption to the storage of secret values”. There are no other changes to the app, and this latest version of Google Authenticator was widely released earlier this week.
