Accessing ProtonMail Through Tor

ProtonMail maintains an official Tor hidden service at protonmailrmez3lotccipshtkleegetolb73fuirgj7r4o4vfu7ozyd.onion. This .onion address provides a direct encrypted connection to ProtonMail's servers through the Tor network, without relying on exit nodes that could potentially be monitored.

Using the .onion address is more secure than accessing proton.me through Tor with a regular URL, because .onion connections never leave the Tor network. There is no DNS resolution that could be intercepted, no exit node that could perform a man-in-the-middle attack, and no TLS certificate authority that could be coerced into issuing a fraudulent certificate.

Bookmark the .onion address in Tor Browser and always verify you are on the correct site. ProtonMail's .onion address is also listed on their official clearnet website for verification purposes.

Navigate to ProtonMail's .onion address in Tor Browser and click Create Account. ProtonMail's free tier requires no phone number or recovery email — you can create a fully anonymous account using only a username and password. For verification, ProtonMail may present a CAPTCHA or request an email verification, but phone verification can usually be avoided over Tor.

Choose a username that does not relate to your real identity or any other online handles. Use a strong, unique password generated by a password manager like KeePassXC (which works offline and stores no data in the cloud). Do not add a recovery email or phone number, as these create identity links.

ProtonMail's free tier includes 500 MB of storage and limited sending. For higher limits, you can upgrade with Bitcoin or cash payments. ProtonMail's paid plans accept cryptocurrency, which allows you to maintain anonymity even when paying for premium features.

Even with ProtonMail and Tor, email has inherent metadata limitations. Email headers include timestamps, subject lines, and recipient addresses that ProtonMail can see (though they are encrypted at rest on ProtonMail's servers). For communications where metadata is as sensitive as content, consider using Briar or Ricochet instead of email.

When sending emails to non-ProtonMail users, end-to-end encryption is only available if you set a shared password for the message. Otherwise, the email is encrypted in transit (TLS) but decrypted on the recipient's server. For sensitive communications, ensure your recipient also uses ProtonMail or PGP encryption.

Never access your anonymous ProtonMail account from both Tor and clearnet. If you log in once without Tor, your real IP is logged and your anonymity is permanently compromised for that account. Use Tor Browser exclusively for anonymous email accounts, and combine it with a VPN for defense-in-depth.
