ProtonMail

Key Features:

1. End-to-End Encryption:

   • Private Email Communication: ProtonMail uses end-to-end encryption, which means that even ProtonMail itself cannot read your emails. Only the sender and the recipient have the decryption keys, ensuring complete privacy.
   • Zero-Access Encryption: ProtonMail’s servers are designed so that they cannot decrypt or access user messages. This means that even if a hacker gained access to ProtonMail’s servers, they would not be able to read the messages.
   • Encryption for All Emails: ProtonMail encrypts all emails by default, and users can choose to send encrypted messages to non-ProtonMail users as well, using a password that the recipient must enter to decrypt the message.

2. Open-Source Code:

   • Transparency: ProtonMail is open-source, meaning anyone can inspect the code to ensure that it does not have any backdoors or vulnerabilities. This transparency is vital for users who care deeply about privacy and security.
   • Auditability: The open-source nature of ProtonMail allows independent security audits, ensuring that its encryption standards are maintained and that the service remains trustworthy.

3. No Personal Information Required:

   • Anonymous Account Creation: To use ProtonMail, users do not need to provide personal information such as a phone number or alternate email address, enhancing privacy and allowing for anonymous use.
   • Account Recovery Options: Users can create ProtonMail accounts without any personal data, but if they choose to use recovery options, the system will ask for encrypted recovery information that cannot be accessed by ProtonMail.

4. Self-Destructing Messages:

   • Ephemeral Emails: ProtonMail allows users to send self-destructing emails, which automatically delete themselves after a set period of time. This is useful for sending sensitive information that should not be stored indefinitely.
   • Customizable Timers: Users can set a timer for emails to automatically expire after a specified amount of time (from a few minutes to several days), ensuring that sensitive messages are removed from the server after they are read.

5. Secure Communication with Non-Users:

   • Password-Protected Messages: ProtonMail users can send encrypted messages to recipients who don’t use ProtonMail. The recipient is sent a link to access the email, and they must enter a password set by the sender to decrypt the content.
   • No Encryption for External Email Servers: When sending emails to users on other email platforms (like Gmail or Yahoo), ProtonMail encrypts the content between ProtonMail servers and the recipient’s server. However, it is not encrypted when stored on the recipient’s server unless additional encryption is used.

6. Two-Factor Authentication (2FA):

   • Enhanced Security: ProtonMail supports two-factor authentication (2FA), providing an extra layer of security to protect your account from unauthorized access. Users can enable 2FA using either a time-based one-time password (TOTP) or via apps like Google Authenticator or Authy.

7. Custom Domains (ProtonMail for Business):

   • Branding and Customization: ProtonMail allows businesses to use their own custom domain names (e.g., yourcompany.com), providing a professional and secure email experience with ProtonMail’s encryption and privacy features.
   • Business Features: ProtonMail offers plans designed for businesses, which include additional features such as support for multiple users, larger storage capacity, and enhanced administrative controls.

8. ProtonMail for Mobile Devices:

   • Mobile App Support: ProtonMail has mobile applications for both iOS and Android devices, allowing users to send and receive encrypted emails on the go.
   • Push Notifications: Users can enable push notifications for incoming emails on their mobile devices, while maintaining full encryption and security.

9. Secure Contacts and Folders:

   • Encrypted Address Book: ProtonMail offers a secure address book where contact information is also encrypted, ensuring that contact details remain private.
   • Organize Emails: Users can organize emails into folders, labels, and tags while keeping them encrypted for secure storage.
   • Filter and Search: ProtonMail has powerful filtering and search features that help users find emails quickly without compromising privacy.

10. ProtonVPN Integration:

    • VPN Service Integration: ProtonMail is part of the Proton ecosystem, which includes ProtonVPN, a secure VPN service. Using ProtonVPN in conjunction with ProtonMail ensures enhanced security and privacy when browsing the internet and checking emails.
