There is a phishing attack happening now in which people are falsely being told to change their passwords for this forum, using links to “ietsencrypt.org” (letter “i”) which is written with a capital I to look visually like “letsencrypt.org”.
If you followed such a link to the false forum site and “changed your password”, please log in directly to this forum site and change your password again. If you received such a false password-change e-mail message, please ignore it.
