by default they require a google account to be able to access the play store on android, but you can use the aurora store app to access it without a google account. you can find it on f-droid.

though be aware that in a year or two google wants to lock out all apps they don’t like, by inserting a check into your phone so that only apps approved by them can be installed from any store. aurora, newpipe and lots of others are not expected to make it.
you are affected if you have google services installed to your phone. this includes if you have the factory operating system on it.
