How can I recover my encryption key?
If you're part of an organization, contact your administrator. While the old encryption key will be lost forever, he will be able to create and provide you with a new one which will give you back access to your account.
Warning: if you're the company administrator or a single user, the encryption key is neither recoverable by you, Bernstein or anyone else.
If you forget or lose it, it is gone.
We therefore highly recommend creating a backup, be it written on a piece of paper safely stored away or in a password manager such as Clipperz.
