Mullvad, (the vpn, I have not tried the browser) uses a single account number as both name and password, no emails. It allows for multiple anonymous payment methods and it’s open source.

Sliiiiightly more trustworthy than Google imo.

If you don’t trust anyone the internet (or any net you don’t fully control yourself) is not something you will use.

Practical security is a matter of threat-modeling and calculated risks.

Mullvad has a good track record, but if you know of better alternatives that don’t require building it yourself, please share!

And Mullvad is not in business if selling user profiles to advertisers, at least as far as we know
