I used Bitwarden for a long time and it was easy and convenient. I’ve since switched to KeePassXC which is less convenient, but it’s more private and secure because it’s offline. I wouldn’t recommend it to someone less tech savvy unless they are just going to need access to their passwords on one device as setting it up reliably with a cloud solution isn’t always simple.

I chose Mullvad because they don’t ask for any personal details and you can pay anonymously, which means that their service is privacy protecting by design. You don’t have to rely so much on trust.

Proton seems to be a large and rapidly expanding company which looks like it’s trying to be a more privacy respecting competitor to Google’s many services. While that’s not necessarily a bad thing, I prefer companies that value stability over rapid expansion. I also don’t like relying on a potential single point of failure for everything. I have a Proton e-mail account but I don’t use any of their other services because I don’t want everything in the same place.

Maybe I was lucky, but I had the same issue where I no longer had access to my old e-mail account and they sorted it out for me within a few hours (after a few e-mails back and forth).

It probably helped that I was able to provide them with a screenshot of the game in my Steam library as well as a list of all the games linked to my Rockstar account with dates of purchase. To find the dates of purchase on Steam I went to “account details” and “view purchase history”.
