I read the website, but I couldn’t see how the account syncing occurs between the mobile apps and the browser extensions. I installed the browser extension but didn’t see a way to make an account. Do I have to self-host the data for syncing?

I moved my TOTP’s from Authy to Bitwarden, where you can have access to your seeds and export if you want. But I believe this requires paying the $10 per year for Bitwarden premium (which I already had).

I don’t really have questions about OF beyond getting context for the billboard. In the US I don’t see porn stars advertising in such everyday places. I have certainly seen billboards that are similar to the one shown in this article, but those are from companies with a big advertising budget like Victoria’s Secret, as you mention. I think porn stars are generally not wealthy enough to have a big advertising budget for billboards.

I’m ignorant about what content OnlyFans has. Is the woman on the billboard a porn star?
