How to Get Started With ProtonMail
Setting up a ProtonMail account is easy, and you don’t have to share any personal information at all, although the service may log the IP address of your location when you sign up. To set up a new account at ProtonMail:
Securely Access ProtonMail
When you use a browser to access ProtonMail, log in at https://mail.protonmail.com/login and make sure the browser shows a verified and validated security certificate for the site. Look for a lock symbol in the address bar.
ProtonMail and POP, IMAP, and SMTP
ProtonMail does not offer IMAP or POP access, and you cannot send email using your ProtonMail address via SMTP. You cannot set up ProtonMail in Microsoft Outlook, macOS Mail, Mozilla Thunderbird, iOS Mail, or other email clients. Similarly, you cannot forward your ProtonMail to another address.
Download Your Public ProtonMail PGP Key
Others can send you encrypted emails at ProtonMail as long as their email service provider uses inline OpenPGP, and they have your public PGP key. To share your public PGP key, upload it to a key server such as the MIT PGP public key server. From there, email programs can fetch the key automatically. To get a copy of the public PGP key for your ProtonMail email address:
Turn on Authentication Logs in ProtonMail
To have ProtonMail log all attempts to access your account and the IP address of each log-in attempt, turn on authentication logs.
