Answers for private customers

The Knowledge Base for private customers is already largely up to date. A few individual articles are currently being revised and adapted. We thank you for your understanding and look forward to providing you with up-to-date information on using mailbox.

Please note: The knowledge base has changed slightly. Categories have been adapted and URLs stored in the old knowledge base may no longer be valid.

Where can I find the PIN for external users

Note: To use the functions described in this article, you must have the mailbox Guard activated.

When you send an encrypted message to someone who does not have a mailbox account and for whom you have not stored a public key in the key management, a temporary mailbox at mailbox will automatically be created for that person. This ensures secure communication. This mailbox can also be protected with a one-time PIN, since the access link itself is transmitted unencrypted. You should therefore provide the PIN to the recipient via a secure side channel (e.g., phone, SMS, or in person).

Important: In the current interface, the PIN can no longer be viewed after sending. Unlike before, there is no longer a function such as “Check assigned PIN.” The PIN is also not permanently stored in the source text.
Therefore: Be sure to save the one-time PIN before sending the mail. Without this PIN, the recipient cannot access the temporary mailbox.

Please note: Temporary mailboxes are automatically deleted after 90 days of inactivity.
