Errr I might not be the best person to ask since I’m still learning 😅 Seems like it’s a unique address for the nym you’re using. And then if you switch to your real profile, it also has an address. Think that’s how it works? 🤔 Each profile has a unique address allowing you to keep privacy amongst profiles. And ya, I think it’s permanent, unless you use incognito mode. That generates a new nym every time. Hope that helps 🙏
