Authenticating apps is an annoying but seemingly necessary feature of modern life. Lots of apps now require it and various apps are trying to get us to use their authenticator services. All except Facebook (sorry, Meta), who recently told us that users can no longer authenticate via its own app (which didn't work anyway) and that we'll need a third-party authenticator. That's where Google's Authenticator comes in.
The Google Authenticator app was previously grey (see above, left), showed Google's 'G' with a lock, and was, let's face it, on the dull side. Although it was an outlier when compared to Google's other apps, which many have complained are too similar looking (see below).
