Aurora Store allows you to install applications anonymously from the Google Play store without needing to login. You will need to login to install paid apps tied to your google account.

The simple way to install applications is to open Aurora and search.

Sometimes search does not find the application you are looking for. Have no fear, there's an alternative way to install apps through aurora.

Open a chrome based browser. (Chromium, Bromite, UnGoogled Chromium, or Vanadium)

Search for the App's Google Play Store page & Click the link

Open with Aurora Store, Voila.
