It is very important to keep PUK and Admin PIN of a TSS stored securely.
If the TSS is still in the state
CREATED, an idempotent request to the SIGN DE API endpoint createTss with the corresponding
tss_id as path parameter will return the PUK of the TSS.
In case the TSS already has a different state, unfortunately there is no direct way to access the PUK. In this case, please send us a support ticket with the corresponding
tss_id (email@example.com), so that we can coordinate the further procedure.
