Empowering you to choose a better internet where privacy is the default. Protect yourself online with Proton Mail, Proton VPN, Proton Calendar, Proton Drive. Proton Pass and SimpleLogin.
Proton Mail is the world's largest secure email provider. Swiss, end-to-end encrypted, private, and free.
Proton VPN is the world’s only open-source, publicly audited, unlimited and free VPN. Swiss-based, no-ads, and no-logs.
Proton Calendar is the world's first end-to-end encrypted calendar that allows you to keep your life private.
Proton Drive is a free end-to-end encrypted cloud storage that allows you to securely backup and share your files. It's open source, publicly audited, and Swiss-based.
Proton Pass Proton Pass is a free and open-source password manager which brings a higher level of security with rigorous end-to-end encryption of all data (including usernames, URLs, notes, and more) and email alias support.
SimpleLogin lets you send and receive emails anonymously via easily-generated unique email aliases.
I believe it is using SimpleLogin in the background. I tested out simple login integration with bitwarden and found the proton pass implementation, plus integration with proton mail to be far superior. I use a fake email with every new sign up and don't really hesitate to sign up for random shit anymore cuz I can just delete the email address.
I believe proton will also include it in their mail offering. I don't buy proton mail because their free tier is more than sufficient for me. I only subscribe to the proton pass for now which is a good deal because the simplelogin stuff comes free with it. I did quite a bit of research, comparing bitwarden + simplelogin/fastmail, 1password + fastmail, etc. proton pass comes out ahead in terms of value though I'd say it's late stage beta software more than a complete package like bitwarden or 1password. I believe it'll have feature parity soon though.
