**(4) What is a valid security certificate?**
**(4) How can I use an invalid security certificate / IMAP STARTTLS / an empty password?**
Valid security certificates are officially signed (not self signed) and have matching a host name.
Invalid security certificate: you should try to fix this by contacting your provider or by getting a valid security certificate
because invalid security certificates are insecure and allow [man-in-the-middle attacks](https://en.wikipedia.org/wiki/Man-in-the-middle_attack).
If money is an obstacle, you can get free security certificates from [Let’s Encrypt](https://letsencrypt.org).
IMAP STARTTLS: the EFF [writes](https://www.eff.org/nl/deeplinks/2018/06/announcing-starttls-everywhere-securing-hop-hop-email-delivery):
"*Additionally, even if you configure STARTTLS perfectly and use a valid certificate, there’s still no guarantee your communication will be encrypted.*"
Empty password: your username is likely easily guessed, so this is very insecure.
If you still want to use an invalid security certificate, IMAP STARTTLS or an empty password,
you'll need to enable insecure connections in the advanced settings and also in the account and/or identity settings.
Additionally, IMAP STARTTLS needs to be enabled in the account settings too.

Encryption is [Autocrypt](https://autocrypt.org/) compatible. For security reasons received messages are not decrypted automatically.
Encryption/decryption is a pro feature.
