I use GrapheneOS ony phone and a Mac with the security options as optimized as possible. For most of my emailing etc, I use Tuta and Proton. There are instances however, where having a Google account is beneficial (some apps for example won’t download from Aurora store in anonymous mode).
Is it advisable/possible to create a dummy Google account with minimal ID/credentials? And if so, what are some best practices for doing so?
Or, do I resign myself to the fact that with more control over my data, I have to sacrifice more?
Possibly, but other than that there aren’t any real verification steps when entering info to create an account (you can just add bogus info).
If there is a phone number required, I have used burner numbers in the past which may work.
