Darwin Security от Darwin

Darwin is your privacy layer for the web. Every time you sign up for something, Darwin is right there. A small button next to the email field lets you use a private alias instead of your real address.

What Darwin does:

Detects email and username fields on any website
Lets you pick an existing identity or generate a new alias with one click
Fills the field for you so your real email never touches the site
Shows all emails received on your aliases, right in the popup

Why it matters

Every data breach starts with an email address. Darwin breaks that chain. Each service gets a unique alias, so a breach at one site cannot be used to attack you elsewhere.
