ProtonMail Security for a Safer Email Experience

With ProtonMail's two-factor authentication, you can add an extra layer of security to your account by requiring a verification code sent to your phone or authenticator app in addition to your password. This makes it much harder for attackers to gain access to your account.

ProtonMail's secure servers are located in Switzerland, a country known for its strong data protection laws.
