Creating a backup of your PGP key

Emails that have been encrypted by your communication partners using your public key and then transmitted to our servers can only be converted back into plain text with the matching private key and the corresponding password. The same applies if you have activated the encrypted mailbox.

We, the team at mailbox, do not have any replacement or secondary key. Even if you have stored your private key in Guard, we cannot decrypt your encrypted emails because the key itself is protected by a password. We have no way whatsoever to restore the plain text of your emails. If we could do that, encryption would be pointless and would not provide any real security benefit to you.

Therefore, please always keep a backup of your private key in a safe place, for example in an encrypted container file. For the associated passwords, we recommend keeping a backup in an encrypted password database such as KeePass or KeePassX.
