This episode discusses the vulnerabilities of using a single email address for multiple online services, which can lead to spam, phishing, and relentless tracking. It introduces Simple Login, an open-source solution that uses email aliases to protect users’ real email addresses. These aliases act as forwarding addresses, hiding the user’s actual email from websites and preventing cross-site tracking. Simple Login offers features like custom domain names, catch-all aliases, support for multiple email accounts, and robust security measures, including PGP encryption and two-factor authentication. The document also explores the option of self-hosting Simple Login for ultimate control over one’s email aliases, detailing the necessary components and setup process.
