This is by far and away the best email masking application on the market right now, and I have used many for over a decade.

Open source, secure, with a plethora of options including multiple inboxes for forwarding, custom domains, and PGP encryption. I have no fear that they are reading my emails for marketing purposes. If you use Proton Mail (highly recommended), the integration is seamless and highly secure.

Highly recommended.

Great service, I use it all the time

Love the service this extension facilitates. It's revolutionizing my email experience. Extension itself is easy to use, and very clear. Great job Simplelogin (and happy it's now part of Proton's product suite).

You'd think having to create a custom address for every website registration would slow you down, but it doesn't with Simplelogin. Quick , easy, efficient. Not sure why I waited so long to start using Simplelogin.

I don't know how I could live without simple login before. Creating aliases and using them couldn't be simpler.

Great product, great integration in Firefox !
