Aliasing
Email & Card Aliasing Services (2025)
Aliasing tools help protect your identity by generating unique email addresses, phone numbers, or payment cards for each service you use. These privacy tools reduce digital exposure, limit tracking, and prevent spam — letting you keep your real information private.
Proton Pass
Proton Pass is a secure, open-source password manager from Proton. It includes built-in integration with SimpleLogin for creating email aliases directly from your vault — protecting both your credentials and identity in one place.
SimpleLogin
SimpleLogin makes it effortless to create and manage private email aliases. Fully open-source and privacy-first, it can be self-hosted or used via Proton Pass. SimpleLogin keeps your real inbox hidden while maintaining easy forwarding and replies.
addy.io
addy.io (formerly AnonAddy) is an open-source, privacy-focused aliasing service. It offers generous free options for creating and managing email aliases, making it an excellent alternative to SimpleLogin and Proton Pass.
MySudo
MySudo provides phone number aliasing and private communication features. Users can create multiple virtual phone numbers and email identities, allowing for compartmentalized communication without revealing personal information.
Privacy.com
Privacy.com allows users to generate unique virtual payment cards for online shopping. It helps prevent fraud and data leaks by isolating transactions — keeping your real credit card details private and secure. (Currently available in the U.S. only.)
Guerrilla Mail
Guerrilla Mail offers quick and disposable temporary email addresses. Ideal for one-time registrations or verification codes, it provides a simple and fast way to stay anonymous and avoid spam in your main inbox.
Aliasing protects your personal data by minimizing how often your real identity is exposed online. Whether for email, phone, or payment data — these tools are essential for reducing your digital footprint and staying private in today’s connected world.
