As part of our effort to provide the highest level of security and privacy to
Proton Mail users, we have upgraded every single SSL certificate that we use.
A lot of good has certainly resulted from the Internet revolution, but one
important freedom that has been threatened in the process is our right
to privacy
We have upgraded our SSL certificate! The new fingerprint can be found in our
knowledge base: https://pme.protonblog.tech/support/protonmails-ssl-certificate
